Technical Specifications - SKF 6200-2RSH/C3GJN

Important: The 2RSH, C3 and GJN suffixes are essential parts of this bearing's technical specification. Bearings with identical dimensions but different seals, internal clearance or grease may not provide equivalent operating performance.

What Does SKF 6200-2RSH/C3GJN Mean?

6200 - Single-Row Deep Groove Ball Bearing

The designation 6200 identifies a single-row deep groove ball bearing belonging to the 62 dimensional series.

Its principal dimensions are:

• Bore diameter d: 10 mm.

• Outside diameter D: 30 mm.

• Width B: 9 mm.

The bearing contains balls running between the deep raceways of the inner and outer rings.

This construction is primarily designed to support radial loads while also accommodating appropriate axial loads in both directions.

2RSH - SKF Contact Seals on Both Sides

The 2RSH suffix indicates contact seals installed on both sides of the bearing.

SKF RSH seals are designed to protect the bearing interior against contamination and reduce lubricant loss.

Their functions include:

• Limiting the entry of dust and fine contaminants.

• Protecting the balls and raceways.

• Helping retain grease inside the bearing.

• Reducing the risk of premature wear caused by contamination.

• Allowing operation without an external relubrication system under suitable conditions.

Contact seals may generate greater frictional torque than metal shields or non-contact seals.

They do not make the bearing completely waterproof.

C3 - Radial Internal Clearance Greater Than Normal

The C3 suffix indicates radial internal clearance greater than normal.

Internal clearance describes the possible relative displacement between the bearing rings before installation, resulting from the bearing's internal geometry.

After installation, the operating clearance may change due to:

• The fit of the inner ring on the shaft.

• The fit of the outer ring in the housing.

• Thermal expansion of components.

• Temperature differences between the bearing rings.

• Operating load conditions.

C3 clearance may be required in applications where mounting fits and operating temperatures significantly reduce internal clearance during operation.

C3 does not automatically mean greater load capacity or higher bearing quality. It is a specific internal clearance class that must be selected according to the machinery design.

GJN - SKF Grease Specification

The GJN suffix identifies a specific grease specification used by SKF.

It is not a designation for internal clearance, sealing arrangement or precision class.

It indicates that the manufacturer has specified a particular lubricant for this bearing version.

When selecting a replacement, the following factors should be considered:

• Grease type.

• Thickener type.

• Base oil properties.

• Operating temperature range.

• Compatibility with the sealing materials.

• Load and speed conditions.

• Compatibility with other lubricants, where relevant.

The exact properties of GJN grease, including its composition, base oil viscosity and permissible operating temperature range, should be confirmed using SKF documentation for this particular bearing version.

A bearing with the same dimensions but a different lubricant must not automatically be considered equivalent.

Alternative Designations and Search References

The bearing may appear in technical catalogues, distributor listings and purchasing enquiries under the following written variations:

• SKF 6200-2RSH/C3GJN

Construction of SKF 6200-2RSH/C3GJN

Single-Row Deep Groove Construction

The bearing consists of an inner ring, an outer ring, balls, a cage and seals on both sides.

The balls roll along precisely formed raceways, allowing the shaft to rotate relative to the housing.

The deep groove construction is suitable for supporting radial loads and appropriate axial loads.

Inner Ring - 10 mm Bore

The nominal bore diameter is 10 mm.

The inner ring is designed to fit onto a shaft with an appropriate tolerance.

The mounting fit is particularly important for C3 bearings because an interference fit may reduce radial internal clearance.

Outer Ring - 30 mm Outside Diameter

The nominal outside diameter is 30 mm.

The outer ring is designed for installation in a compatible housing bore.

An incorrect mounting fit may cause ring movement, excessive stress or changes in operating clearance.

Bearing Width - 9 mm

The bearing has a nominal width of 9 mm.

This dimension is important when mounting the bearing between shaft shoulders, retaining rings and spacing components.

Double 2RSH Contact Seals

The seals help prevent external contaminants from reaching the rolling elements.

They are particularly useful in mechanisms where additional external sealing arrangements are difficult to incorporate.

Understanding C3 Internal Clearance

Why Is C3 Clearance Used?

During installation and operation, the bearing's internal clearance may decrease.

This can result from interference fits and temperature differences between the bearing rings.

A greater initial clearance may allow the bearing to achieve the required operating clearance after these effects are taken into account.

Is C3 Better Than Normal Clearance?

Not in every application.

C3 clearance is appropriate when required by the machinery design.

Excessive operating clearance may negatively affect noise, vibration and shaft positioning accuracy.

Insufficient operating clearance may increase friction, operating temperature and the risk of bearing damage.

Can a C3 Bearing Be Replaced with Normal Clearance?

Only after confirming that the change is technically acceptable.

If the equipment manufacturer specifies C3 clearance, this requirement should be maintained unless an engineering assessment supports a different selection.

Understanding SKF GJN Grease

Why Is the Grease Designation Important?

Lubricant properties influence friction, operating temperature, protection of rolling contact surfaces and bearing service life.

Two bearings with identical dimensions and seals may perform differently if they contain different lubricants.

Can GJN Grease Be Replaced with Another Grease?

Full interchangeability should not be assumed without verifying lubricant properties.

Important factors include operating temperature, speed, load and grease compatibility.

Does the Bearing Require Relubrication?

Deep groove ball bearings sealed on both sides are generally supplied with factory-applied grease.

However, this does not mean that the lubricant has an unlimited service life.

Grease life depends on temperature, speed, loading and environmental conditions.

The seals should not be removed and another grease should not be introduced without a valid technical reason.

SKF 6200-2RSH/C3GJN vs Other 6200 Bearing Versions

6200-2RSH/C3GJN vs 6200-2RSH

Both bearings have the same principal dimensions of 10x30x9 mm and use 2RSH seals.

However, the C3GJN version includes additional specifications for internal clearance and grease.

The absence of these suffixes in another product designation does not confirm identical technical characteristics.

6200-2RSH/C3GJN vs 6200-2RSH/C3

Both designations indicate 2RSH contact seals and C3 radial internal clearance.

The GJN suffix additionally identifies a specific grease specification.

When selecting a replacement, it is necessary to confirm whether the lubricant used in the alternative bearing meets the application requirements.

6200-2RSH/C3GJN vs 6200-2Z/C3

The 2RSH version uses contact seals, while the 2Z version uses metal shields.

This difference affects contamination protection and friction characteristics.

6200 vs 6000

The 6200 and 6000 bearings have the same nominal bore diameter but different outside dimensions.

They are not directly interchangeable in terms of dimensions.

Load-Carrying Capability and Operating Conditions

Radial Loads

The 6200 bearing is primarily designed to support radial loads.

Radial loads act perpendicular to the shaft axis.

The exact basic dynamic and static load ratings for the specific bearing version should be verified using the SKF catalogue.

Axial Loads

The deep groove construction allows the bearing to accommodate appropriate axial loads in both directions.

Permissible values depend on radial loading, internal geometry and operating conditions.

Rotational Speed

The permissible operating speed depends on bearing construction, seals, grease, loading and temperature.

The limiting speed of an open or 2Z bearing must not automatically be applied to the 2RSH/C3GJN version.

Operating Temperature

The permissible operating temperature depends on the bearing materials, seals and properties of GJN grease.

The exact temperature range of this bearing version requires confirmation from SKF documentation.

Applications of SKF 6200-2RSH/C3GJN

The bearing can be used in mechanisms requiring support for a 10 mm shaft, double contact sealing, greater-than-normal radial internal clearance and a specified grease formulation.

Potential applications include:

• Compact drive assemblies.

• Electromechanical equipment.

• Selected electric motor designs.

• Roller and pulley mechanisms.

• Industrial machinery.

• Equipment with limited bearing access.

• Assemblies requiring contact seals.

• Mechanisms requiring C3 clearance and a specified lubricant.

These are potential applications based on the bearing's construction, not a confirmed list of specific machinery models.

The equipment manufacturer's requirements must be checked before installation.

Can a Standard 6200 2RS Replace SKF 6200-2RSH/C3GJN?

Such interchangeability must not be assumed automatically.

Although both bearings have dimensions of 10x30x9 mm, they may differ in seal design, internal clearance and grease specification.

If the equipment manufacturer requires C3GJN, these specifications should be maintained or technically verified before substitution.

Can a Bearing from Another Manufacturer Be Used as a Replacement?

An alternative bearing may be considered if it meets the dimensional, sealing, internal clearance, lubrication and operating requirements.

Identical dimensions alone do not guarantee full technical equivalence.

Why Is the Complete Designation Important?

The complete designation identifies technical features beyond the basic dimensions.

For this bearing, the 2RSH, C3 and GJN suffixes describe important aspects of sealing, internal clearance and lubrication.

Ignoring these specifications may result in an unsuitable replacement even when the bearing fits into the existing housing.

Installation of SKF 6200-2RSH/C3GJN

Shaft and Housing Preparation

Before installation, inspect the shaft and housing bore.

The mating surfaces should be clean and free from burrs, corrosion and mechanical damage.

Selecting the Correct Mounting Fit

The mounting fit should be selected according to loading conditions, operating temperature and required operating clearance.

For a C3 bearing, the effect of interference fits on radial internal clearance is particularly important.

Correct Application of Mounting Force

When mounting the bearing onto a shaft, apply the installation force directly to the inner ring.

When pressing the bearing into a housing, apply the installation force directly to the outer ring.

Mounting forces must not be transmitted through the balls.

Protecting the 2RSH Seals

Do not damage or remove the 2RSH seals during normal installation.

Seal damage may result in grease loss or increased contamination of the bearing interior.

Operating Inspection

During operation, monitor the bearing for:

• Unusual noise.

• Excessive vibration.

• Abnormal temperature rise.

• Increased rotational resistance.

• Seal damage.

• Signs of grease loss.

• Wear-related changes in clearance.
