SKF 6000-2Z/C3 10x26x8 - Deep Groove Ball Bearing

SKF 6000-2Z/C3 10x26x8 mm - Single Row Deep Groove Ball Bearing

SKF 6000-2Z/C3 is a single row deep groove ball bearing from the SKF 6000 series, measuring 10x26x8 mm. It features two non-contact metal shields, increased C3 radial internal clearance, a pressed steel cage and factory grease lubrication. Its deep raceway grooves enable it to accommodate radial loads and axial loads in both directions. The commercial designation SKF 6000 ZZ C3 corresponds to the 2Z/C3 configuration, although the manufacturer's full designation should be confirmed on the product or packaging.

Technical Specifications - SKF 6000-2Z/C3

The specifications refer to SKF 6000-2Z/C3. Values for open bearings or versions with contact seals should not automatically be applied to this execution.

What Does SKF 6000 ZZ C3 Mean?

6000 - Basic Bearing Designation

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

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

ZZ / 2Z - Two Metal Shields

ZZ is a commonly used commercial designation for a bearing with two metal shields. SKF uses the suffix 2Z.

The shields are fitted on both sides of the bearing.

Unlike contact seals, metal shields do not normally contact the rotating ring, avoiding the friction associated with contact sealing lips.

Their main functions are to:

• Reduce the entry of contaminants into the bearing.

• Help retain grease inside the bearing.

• Provide protection for the raceways and rolling elements.

• Support operation where low sealing friction is important.

However, non-contact metal shields do not provide the same level of protection against moisture and fine contaminants as appropriately selected contact seals.

C3 - Increased Radial Internal Clearance

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

Increased clearance may be required where interference fits or operating temperature differences reduce the available internal clearance.

C3 does not indicate increased load capacity, a higher tolerance class or automatically better performance.

These written variations refer to the same basic bearing configuration.

The manufacturer's designation 6000-2Z/C3 should be used when ordering.

Construction and Operating Principle

SKF 6000-2Z/C3 consists of an inner ring, an outer ring, a single row of balls and a pressed steel cage that maintains the spacing between the rolling elements.

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

Permissible axial loading depends on operating conditions and must be evaluated separately from the basic dynamic load rating.

Two non-contact metal shields help retain the factory-applied grease and reduce contamination of the bearing interior.

Because the shields do not generate the same contact friction as elastomer sealing lips, this design is suitable for consideration in applications requiring relatively high rotational speeds.

Why Is C3 Clearance Important?

During installation, interference fits can reduce radial internal clearance through elastic deformation of the bearing rings.

Additional clearance changes may occur during operation because of temperature differences between the inner and outer rings.

C3 clearance provides greater initial radial internal clearance than the normal CN execution.

However, increased clearance is not automatically preferable.

Insufficient operating clearance can increase friction and operating temperature, while excessive clearance may contribute to vibration, noise and unfavorable rolling element loading.

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

SKF 6000-2Z/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 does not represent 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 the risk of permanent deformation at the rolling element and raceway contacts.

It is relevant for stationary bearings, very low rotational speeds and high static loads.

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 force acting on the bearing.

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 - 34,000 rpm

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

Actual permissible operating speed must also account for load, temperature, lubrication and the bearing arrangement.

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

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

All these variants share the same basic dimensions of 10x26x8 mm, but they are not automatically interchangeable.

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

Both bearings have dimensions of 10x26x8 mm and two metal shields.

The difference is radial internal clearance:

• SKF 6000-2Z has normal CN clearance.

• SKF 6000-2Z/C3 has increased C3 clearance.

The correct execution depends on shaft and housing fits, operating temperature and the required operating clearance.

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

Both bearings have increased C3 radial internal clearance, but their protective arrangements differ.

SKF 6000-2Z/C3 uses two non-contact metal shields, while SKF 6000-2RSH/C3 incorporates two contact seals.

The SKF catalogue limiting speed for 6000-2Z/C3 is 34,000 rpm, compared with 19,000 rpm for 6000-2RSH/C3.

Selection depends on rotational speed, contamination protection and operating conditions.

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

Both bearings have increased C3 radial internal clearance and identical boundary dimensions.

SKF 6000/C3 is open and requires lubrication from the machine's bearing arrangement.

SKF 6000-2Z/C3 has two metal shields and is supplied with factory-applied grease.

The lubrication and contamination protection requirements are therefore different.

Bearing Selection and Interchangeability

Before ordering SKF 6000-2Z/C3, verify the following requirements:

• Exact SKF designation 6000-2Z/C3.

• Bore diameter of 10 mm.

• Outside diameter of 26 mm.

• Bearing width of 8 mm.

• Increased C3 radial internal clearance.

• Two non-contact metal shields.

• Rotational speed.

• Radial and axial operating loads.

• Shaft and housing fits.

• Operating temperature.

• Exposure to dust, moisture and other contaminants.

• Lubrication requirements.

• Cage and tolerance requirements, where applicable.

Identical dimensions do not guarantee complete technical interchangeability.

A bearing from another manufacturer with dimensions of 10x26x8 mm may have different internal clearance, shield geometry, grease or operating characteristics.

Applications of SKF 6000-2Z/C3

SKF 6000-2Z/C3 can be considered for compact rotating shaft arrangements requiring a 10 mm bore, increased radial internal clearance and two metal shields.

Its design is relevant where relatively low sealing friction, high rotational speed and grease retention are important.

The deep groove ball bearing construction supports radial loads and axial loads in both directions, subject to appropriate bearing load calculations.

Final selection must account for operating loads, speed, temperature, fits and environmental conditions.

Specific machinery models or OEM applications should not be attributed to SKF 6000-2Z/C3 without supporting manufacturer documentation.

Installation and Operating Recommendations

Cleanliness Before Installation

Clean the shaft, housing and mating surfaces before mounting.

Protect the bearing against 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.

Protection of Metal Shields

The metal shields must be protected against deformation during installation.

Do not apply mounting tools directly to the shields.

Shaft and Housing Fits

Select the appropriate fits according to loading conditions, operating temperature and required internal clearance.

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

Lubrication

SKF 6000-2Z/C3 is supplied with factory-applied grease.

The standard shielded execution is not intended for routine relubrication.

Storage

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

Protect it against moisture, corrosion and mechanical damage.
