Technical Specifications - 6200 2RS C3 FG KOYO

The load ratings, speed, chamfer dimension and weight are based on the catalogue specification for KOYO 6200 2RS. For the specific 6200 2RS C3 FG version, the FG cage specification and any associated operating limitations should be confirmed against the documentation for the supplied bearing.

What Does 6200 2RS C3 FG KOYO Mean?

6200 - Single-Row Deep Groove Ball Bearing

The designation 6200 identifies a deep groove ball bearing from the 62 dimensional series.

The designation consists of:

• 6 - deep groove ball bearing.

• 2 - dimensional series 62.

• 00 - bore diameter code corresponding to 10 mm.

The bearing has dimensions of 10x30x9 mm.

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

2RS - Contact Seals on Both Sides

The designation 2RS indicates contact seals installed on both sides of the bearing.

The seals separate the balls and raceways from the surrounding environment.

Their functions include:

• Reducing the entry of dust and contaminants.

• Retaining grease inside the bearing.

• Protecting the rolling elements.

• Limiting moisture ingress under suitable conditions.

• Reducing the need for external lubrication maintenance.

Contact seals generate additional friction compared with open bearings or bearings fitted with non-contact metal shields.

They do not provide complete waterproofing.

C3 - Greater Than Normal Radial Internal Clearance

The C3 designation identifies increased radial internal clearance.

C3 clearance is greater than standard CN clearance.

It may be required when:

• The bearing is installed with an interference fit.

• The inner ring operates at a higher temperature than the outer ring.

• Differences in thermal expansion occur.

• Mounting conditions reduce the operating internal clearance.

C3 does not indicate a higher precision class or automatically increased load-carrying capacity.

The appropriate clearance must be selected according to mounting conditions and operating temperature.

FG - Cage Design

In commercial listings for KOYO 6200 2RS C3 FG, the FG designation is associated with a polyamide cage.

The cage maintains the correct spacing between the balls and reduces direct contact between adjacent rolling elements.

Compared with certain metal cage designs, a polymer cage may provide different friction, vibration and noise characteristics.

However, this does not mean that every bearing with a polyamide cage will operate more quietly under all conditions.

The exact cage material, permissible operating temperature and performance characteristics should be confirmed for the specific bearing version.

Alternative Designations and Reference Numbers

The product may be searched for using the following variations:

• 6200 2RS C3 FG KOYO

• KOYO 6200 2RS C3 FG

• 6200-2RS-C3-FG KOYO

• KOYO 6200 2RS C3

• 6200 2RS FG KOYO

• 6200 2RS C3 FG 10x30x9

• KOYO 6200 C3 2RS bearing

• KOYO 10x30x9 C3 deep groove ball bearing

Shortened designations can be useful when identifying a product.

However, the complete specification should be considered when ordering, particularly C3 clearance, 2RS seals and the FG cage design.

Construction of 6200 2RS C3 FG KOYO

Single-Row Ball Arrangement

The bearing uses a single row of balls positioned between the inner and outer rings.

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

Inner Ring - 10 mm Bore

The bore diameter is 10 mm.

The inner ring operates with a shaft having an appropriately selected mounting fit.

Excessive interference may reduce internal clearance beyond the intended operating range.

Outer Ring - 30 mm Outside Diameter

The outside diameter is 30 mm.

The outer ring should be installed in a housing with suitable dimensional tolerances and geometry.

Bearing Width - 9 mm

The bearing width is 9 mm.

This dimension is important when designing axial shoulders, spacers and locating components.

FG Polyamide Cage

The cage maintains the correct spacing between the balls and guides them during operation.

Its operating characteristics depend on the material used and the application conditions.

2RS Contact Seals

Two contact seals help retain grease and limit the entry of contaminants.

The condition of the seals directly affects the protection of the balls and raceways.

Load Ratings and Rotational Speed

Basic Dynamic Load Rating Cr - 6.40 kN

The basic dynamic load rating is 6.40 kN, equivalent to 6,400 N.

This parameter is used in nominal bearing fatigue life calculations.

It must not be interpreted as the maximum permissible operating load.

Basic Static Load Rating C0r - 2.40 kN

The basic static load rating is 2.40 kN, equivalent to 2,400 N.

This parameter is used to evaluate loads that may cause permanent deformation at the contact points between the balls and raceways.

Fatigue Load Limit Cu - 0.120 kN

The catalogue fatigue load limit is 0.120 kN, equivalent to 120 N.

It is used in bearing life calculation methods.

It is not the maximum permissible operating load.

Limiting Speed - 16,000 r/min

The catalogue limiting speed for KOYO 6200 2RS with grease lubrication is 16,000 r/min.

The actual permissible rotational speed depends on loading, temperature, lubrication, mounting fits, seal construction and cage design.

For the special FG version, any operating limitations associated with the cage material must also be considered.

6200 2RS C3 FG KOYO vs Other Bearing Variants

6200 2RS C3 FG vs KOYO 6200 2RS C3

Both designations refer to bearings with dimensions of 10x30x9 mm, contact seals on both sides and C3 radial internal clearance.

The FG designation additionally identifies a cage version in commercial listings.

A bearing without the FG designation must not automatically be assumed to have an identical cage construction.

6200 2RS C3 FG vs KOYO 6200 2RS

The main differences concern radial internal clearance and potentially the cage construction.

A standard 6200 2RS bearing does not necessarily have C3 clearance.

Replacement requires verification of the required operating internal clearance.

6200 2RS C3 FG vs KOYO 6200 ZZ C3 FG

The 2RS version uses contact seals.

The ZZ version uses metal shields and has different contamination protection and friction characteristics.

6200 2RS C3 FG KOYO vs SKF 6200-2RSH/C3

Both products have nominal dimensions of 10x30x9 mm and increased C3 radial internal clearance.

Potential differences include:

• Seal construction.

• Cage material and design.

• Catalogue load ratings.

• Limiting speed.

• Factory-applied lubricant.

SKF technical parameters must not be automatically transferred to the KOYO bearing.

Can 6200 2RS C3 FG Be Replaced with a Standard 6200 2RS?

Not without checking the operating conditions.

The standard version may have normal radial internal clearance and a different cage.

If the equipment requires C3 clearance, installing a CN version may result in unsuitable operating conditions after mounting.

Is an FG Polyamide Cage Better Than a Steel Cage?

There is no single answer for every application.

Polymer and steel cages differ in their mechanical, thermal and tribological properties.

The appropriate choice depends on rotational speed, temperature, lubrication and loading.

Is KOYO 6200 2RS C3 FG Interchangeable with 6200 2RS C3 from Another Brand?

It may be interchangeable after confirming the complete technical specification.

Dimensions, internal clearance, seals, cage, load ratings and operating conditions should be compared.

Identical dimensions do not automatically guarantee full technical equivalence.

Applications of 6200 2RS C3 FG KOYO

The bearing may be used in appropriately designed rotating mechanisms requiring support for a 10 mm shaft, contact seals on both sides and increased C3 radial internal clearance.

Potential application areas include:

• Small electric motors.

• Fans.

• Compact drive assemblies.

• Industrial machine mechanisms.

• Electromechanical equipment.

• Assemblies requiring reduced contamination of rolling elements.

• Systems where mounting or thermal conditions require C3 clearance.

These are general applications based on bearing construction, not confirmed OEM applications for specific equipment models.

Final bearing selection must account for the equipment manufacturer's requirements.

Installation and Operating Recommendations

Surface Preparation

Before installation, inspect the shaft and housing.

Mounting surfaces should be clean and free from burrs and mechanical damage.

Correct Mounting Fits

Mounting fits should be selected according to loading, rotational speed and temperature.

Interference fits may reduce radial internal clearance.

Application of Mounting Force
