SKF 6000/C3 10x26x8 mm - Deep Groove Ball Bearing

SKF 6000/C3 10x26x8 mm - Single Row Deep Groove Ball Bearing

SKF 6000/C3 is a single row deep groove ball bearing from the SKF 6000 series, measuring 10x26x8 mm. It features an open design without integrated seals or shields and increased C3 radial internal clearance. The bearing has a pressed steel cage and deep raceway grooves that accommodate radial loads and axial loads in both directions. The /C3 suffix distinguishes this execution from the standard SKF 6000 bearing with normal internal clearance.

Technical Specifications - SKF 6000/C3

The specifications refer to the open SKF 6000/C3 bearing. Values for shielded, sealed or other clearance executions should not automatically be applied to this product.

What Does SKF 6000/C3 Mean?

6000 - Basic Bearing Designation

The designation 6000 identifies a single row deep groove ball bearing with a 10 mm bore diameter, 26 mm outside diameter and 8 mm width.

It belongs to the SKF 6000 series, which has a smaller cross-section than the 6200 and 6300 series with the same bore diameter.

/C3 - Increased Radial Internal Clearance

The SKF suffix /C3 indicates radial internal clearance greater than normal CN clearance.

Increased clearance is important in bearing arrangements where interference fits or temperature differences between the inner and outer rings can reduce internal clearance during operation.

C3 does not indicate a higher accuracy class, greater load capacity or automatically higher permissible operating speed.

Open Bearing Design

SKF 6000/C3 has no integrated metal shields or elastomer contact seals.

The open construction allows grease or oil to reach the raceways and rolling elements through the machine's lubrication system.

It also requires suitable protection against contamination.

Alternative Designations and Search References

Common written variations include:

• SKF 6000/C3

• 6000/C3 SKF

• SKF6000/C3

• 6000 C3 SKF

• SKF 6000 C3

These refer to the same basic bearing designation. The manufacturer designation 6000/C3 should be preserved when ordering.

Construction and Operating Principle

SKF 6000/C3 consists of an inner ring, an outer ring, a single row of steel balls and a pressed steel cage that maintains the correct spacing between the rolling elements.

The deep raceway grooves allow the bearing to accommodate radial loads and axial loads acting in both directions.

However, permissible axial loading depends on operating conditions and must not be assumed to equal the basic dynamic load rating.

The open design permits grease or oil lubrication supplied by the machine's bearing arrangement.

Why Is C3 Clearance Important?

When a bearing ring is installed with an interference fit, elastic deformation can reduce the available radial internal clearance.

Additional changes can occur during operation when the inner and outer rings reach different temperatures.

C3 clearance provides a greater initial clearance than normal CN clearance, helping accommodate these effects in appropriately designed applications.

However, increased clearance does not automatically improve bearing performance.

Insufficient operating clearance can increase friction, temperature and internal stresses. Excessive operating clearance may contribute to vibration, noise and unfavorable rolling element loading.

The correct clearance must therefore be selected according to the complete bearing arrangement.

SKF 6000/C3 Load Ratings and Operating Speeds

Basic Dynamic Load Rating C - 4.75 kN

The basic dynamic load rating is used to calculate rolling bearing fatigue life under dynamic loading conditions.

It is not a universal maximum permissible operating load.

Actual bearing life depends on equivalent dynamic load, lubrication, contamination and operating conditions.

Basic Static Load Rating C0 - 1.96 kN

The basic static load rating is used to assess permanent deformation at rolling element and raceway contacts.

It is particularly relevant for stationary bearings, low-speed operation and high static loading.

Fatigue Load Limit Pu - 0.083 kN

The fatigue load limit is used in SKF bearing life calculation methods.

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

Reference Speed - 67,000 rpm

The reference speed is a thermal reference value determined under standardized operating assumptions.

It does not represent an unconditional permissible continuous operating speed.

Limiting Speed - 40,000 rpm

The limiting speed reflects mechanical and other practical restrictions affecting bearing operation.

The actual permissible operating speed must be evaluated using the bearing arrangement, load, lubrication method and operating temperature.

The reference speed and limiting speed describe different technical criteria and must not be treated as interchangeable.

SKF 6000/C3 vs Other SKF 6000 Variants

All these variants share the same basic dimensions of 10x26x8 mm, but they differ in radial internal clearance, sealing arrangement or lubrication requirements.

SKF 6000 vs SKF 6000/C3

The main difference is radial internal clearance.

SKF 6000 has normal CN clearance, while SKF 6000/C3 has increased C3 clearance.

These versions should not be substituted without checking the required operating clearance, shaft and housing fits and temperature conditions.

SKF 6000/C3 vs SKF 6000-2Z/C3

Both bearings have increased C3 radial internal clearance.

SKF 6000/C3 is open, while SKF 6000-2Z/C3 has two non-contact metal shields.

The shields help retain lubricant and reduce the entry of contaminants.

This difference affects lubrication requirements and the bearing arrangement's contamination protection.

SKF 6000/C3 vs SKF 6000-2RSH/C3

Both variants have the same basic dimensions and increased C3 clearance.

SKF 6000-2RSH/C3 incorporates two contact seals, whereas SKF 6000/C3 is open.

Contact seals provide a different level of contamination protection but introduce additional friction.

The two executions are not automatically interchangeable.

Bearing Selection and Interchangeability

Before ordering SKF 6000/C3, verify the following technical requirements:

• Exact SKF designation 6000/C3.

• Bore diameter of 10 mm.

• Outside diameter of 26 mm.

• Bearing width of 8 mm.

• Required increased C3 radial internal clearance.

• Open bearing construction.

• Shaft and housing fits.

• Radial and axial operating loads.

• Rotational speed.

• Operating temperature and thermal expansion.

• Lubrication method and lubricant compatibility.

• Protection against contamination.

• Cage and tolerance requirements, where applicable.

A bearing from another manufacturer with dimensions of 10x26x8 mm is not automatically equivalent to SKF 6000/C3.

At minimum, the internal clearance, bearing design, load ratings and operating requirements must be compared.

Applications of SKF 6000/C3

SKF 6000/C3 can be considered for compact rotating shaft arrangements requiring a 10 mm bore and increased radial internal clearance.

Its deep groove ball bearing design supports radial loads and axial loads in both directions.

The C3 clearance execution may be relevant where interference fits or operating temperature differences reduce internal clearance after mounting.

Because the bearing is open, the machine must provide appropriate lubrication and contamination protection.

Specific motor models, gearboxes, machinery references or OEM applications should not be attributed to SKF 6000/C3 without supporting manufacturer documentation.

Installation and Operating Recommendations

Cleanliness Before Installation

Clean the shaft, housing and mating surfaces before mounting.

Protect the raceways and rolling elements from dust, moisture and mechanical damage.

Correct Mounting Force

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

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

Never transmit mounting force through the balls.

Shaft and Housing Fits

Select the appropriate fits according to the load direction, operating conditions and required internal clearance.

Interference fits can reduce radial internal clearance and must be considered when selecting the C3 execution.

Lubrication

SKF 6000/C3 is an open bearing without a factory grease filling intended for service operation.

The bearing arrangement must provide suitable grease or oil lubrication.

Lubricant selection and quantity depend on rotational speed, load, operating temperature and the machine's lubrication system.

Storage

Store the bearing in its original packaging in a clean, dry environment.

Do not remove the factory-applied corrosion protection unnecessarily.
