SKF 629-2RSH 9x26x8 mm - Deep Groove Ball Bearing

SKF 629-2RSH 9x26x8 mm - Single Row Deep Groove Ball Bearing

SKF 629-2RSH is a single row deep groove ball bearing with dimensions of 9x26x8 mm, equipped with two RSH contact seals. According to SKF catalogue specifications, it has a basic dynamic load rating of 4.75 kN, a basic static load rating of 1.96 kN and a limiting speed of 19,000 rpm. The bearing accommodates radial loads and axial loads in both directions. The commercial designation 629 2RS requires confirmation of the exact SKF seal execution.

Technical Specifications - SKF 629-2RSH

These technical specifications apply specifically to SKF 629-2RSH. They should not automatically be assigned to other bearings marketed under the general designation 629 2RS.

What Does SKF 629-2RSH Mean?

629 - Basic Bearing Designation

The designation 629 identifies a single row deep groove ball bearing with a 9 mm bore diameter, 26 mm outside diameter and 8 mm width.

The bearing consists of an inner ring, an outer ring, a single row of balls and a cage that maintains the spacing between the rolling elements.

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

2RSH - Two SKF Contact Seals

The suffix 2RSH identifies two RSH-type contact seals, one on each side of the bearing.

These seals help retain lubricant inside the bearing and reduce the entry of contaminants into the raceways and rolling elements.

Because the sealing lips operate in contact with the mating ring surface, they generate additional friction compared with non-contact shields or low-friction sealing arrangements.

This difference is particularly important when selecting bearings for high-speed applications.

Alternative Designations and Search References

Common commercial written variations include:

• SKF 629-2RSH

• 629-2RSH SKF

• SKF629-2RSH

• SKF 629 2RS

• 629 2RS SKF

The designation 629 2RS is a general commercial description. SKF 629-2RSH identifies a specific manufacturer execution.

The exact suffix should be verified from the bearing marking or original SKF packaging before ordering a replacement.

SKF 629-2RSH vs SKF 629-2RSL

Both bearings have identical dimensions of 9x26x8 mm and the same basic dynamic and static load ratings.

However, they use different sealing arrangements.

SKF 629-2RSL uses a low-friction sealing arrangement and has a higher catalogue limiting speed.

SKF 629-2RSH uses contact seals designed to provide a different level of contamination protection.

The two versions are not automatically interchangeable. Selection must consider the required sealing performance, rotational speed and operating environment.

Bearing Selection and Interchangeability

Before ordering SKF 629-2RSH, verify:

• Exact SKF bearing designation.

• Bore diameter of 9 mm.

• Outside diameter of 26 mm.

• Bearing width of 8 mm.

• Required RSH contact seal design.

• Radial internal clearance requirements.

• Radial and axial operating loads.

• Rotational speed.

• Operating temperature.

• Shaft and housing fits.

• Lubrication conditions.

• Exposure to dust, moisture or other contaminants.

Identical dimensions do not guarantee complete technical interchangeability.

Bearings with different seal designs may have different friction characteristics, operating speed limits and contamination resistance.

Applications of SKF 629-2RSH

SKF 629-2RSH is suitable for consideration in compact rotating shaft arrangements requiring a 9 mm bore, 26 mm outside diameter, 8 mm width and contact seals on both sides.

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

The sealed design is relevant where lubricant retention and protection against contamination are important.

Specific machinery models, equipment applications or OEM references should not be assigned to this part number without supporting manufacturer documentation.

Installation and Operating Recommendations

Cleanliness

Clean the shaft, housing and mating surfaces before installation. Protect the seals against contamination 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.

Mounting force must not be transmitted through the balls.

Bearing Fits

Select the appropriate shaft and housing fits according to the load direction, operating conditions and internal clearance requirements.

Lubrication and Storage

SKF 629-2RSH is supplied with factory-applied grease. The seals should not be removed for routine lubrication.

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

Frequently Asked Questions - SKF 629-2RSH

What are the dimensions of SKF 629-2RSH?

The bearing has a 9 mm bore diameter, 26 mm outside diameter and 8 mm width. Its dimensions are 9x26x8 mm.

What does 2RSH mean in SKF bearing designations?

2RSH indicates two RSH-type contact seals, one fitted on each side of the bearing.

Are SKF 629 2RS and SKF 629-2RSH the same bearing?

Not necessarily. The designation 629 2RS is a general commercial description, while 629-2RSH identifies a specific SKF seal execution.

What is the dynamic load rating of SKF 629-2RSH?

The basic dynamic load rating is 4.75 kN. The basic static load rating is 1.96 kN.

What is the limiting speed of SKF 629-2RSH?

The SKF catalogue limiting speed is 19,000 rpm. Actual operating speed must also account for load, temperature, lubrication and application conditions.

Can SKF 629-2RSL replace SKF 629-2RSH?

Not automatically. Although both bearings have the same dimensions, their seal designs and limiting speeds differ.

Is SKF 629-2RSH factory lubricated?

Yes. The bearing is supplied with factory-applied grease and contact seals on both sides.
