SKF 6008-2RSH 40x68x15 Deep Groove Ball Bearing

SKF 6008-2RSH is a single row deep groove ball bearing with dimensions 40x68x15 mm. It has a 40 mm bore diameter, 68 mm outside diameter and 15 mm width. The 2RSH configuration uses contact seals on both sides, providing a sealed bearing arrangement with the lubricant retained inside the bearing.

SKF 6008-2RSH - Product Characteristics

The 6008 series belongs to the SKF single row deep groove ball bearing family. Its deep raceway geometry allows the bearing to support primarily radial loads together with axial loads acting in both directions.

The technical identification of this variant is:

SKF -> 6008-2RSH -> single row deep groove ball bearing -> 40x68x15 mm -> contact seals on both sides

The sealing configuration is important when distinguishing this bearing from open 6008 bearings and shielded versions such as 6008-2Z.

Dimensions

The catalog dimensions are:

d - Bore Diameter: 40 mm
D - Outside Diameter: 68 mm
B - Width: 15 mm
Dimensions: 40x68x15 mm

For this bearing, the third dimension is correctly identified as the bearing width B = 15 mm.

Deep Groove Ball Bearing Construction

SKF 6008 is a single row deep groove ball bearing. The rolling elements are balls running between deep raceways in the inner and outer rings.

The raceway geometry enables the bearing to accommodate radial loading while also supporting axial load components in both directions.

This does not make the 6008 equivalent to an angular contact ball bearing. Its fundamental construction remains a deep groove ball bearing, and bearing selection should be based on the complete load conditions of the application.

2RSH Sealing Configuration

The suffix 2RSH identifies an SKF bearing with RSH contact seals on both sides.

These seals close both sides of the bearing and help retain the lubricant while limiting contamination entering the rolling contact area.

This construction should be distinguished from:

6008 - open bearing
6008-2Z - shields on both sides
6008-2RSH - contact seals on both sides

The different closure arrangements can affect friction, permissible speed and protection against contamination, so they should not be treated as identical variants.

Load Carrying Capacity

Catalog data for the SKF 6008 bearing family specify:

Basic Dynamic Load Rating C: 17.8 kN
Basic Static Load Rating C0: 11 kN
Fatigue Load Limit Pu: 0.49 kN

These are standardized bearing load ratings and should not be interpreted as the maximum permissible load of a complete bearing arrangement.

Actual bearing life and suitability depend on factors including load magnitude and direction, rotational speed, lubrication, fits, operating temperature and required service life.

Radial and Axial Loads

The primary function of the SKF 6008-2RSH is to accommodate radial loading.

Because of its deep groove raceway geometry, the bearing can also support axial loads in both directions. This makes deep groove ball bearings suitable for bearing arrangements where radial loading is accompanied by moderate axial components.

The actual permissible axial load must be evaluated according to SKF bearing calculation procedures rather than inferred solely from the bearing type.

6008-2RSH vs 6008-2Z

Both variants share the nominal 40x68x15 mm dimensions, but their closure systems differ.

6008-2RSH uses contact seals.
6008-2Z uses metal shields.

Contact seals provide a different balance between contamination protection, friction and speed capability than non-contact shields.

Therefore, identical dimensions do not mean that 6008-2RSH and 6008-2Z should automatically be substituted for one another.

6008 2RS, 6008-2RS1 and 6008-2RSH

The commercial term 6008 2RS is widely used to describe a 6008 bearing sealed on both sides, but SKF uses more specific suffixes.

SKF documentation includes designations such as 6008-2RS1 and 6008-2RSH, depending on the seal design and product generation.

For an industrial product listing, the exact designation printed on the SKF bearing or its original packaging should take priority over the generic abbreviation 2RS.

If the bearing being sold is marked 6008-2RS1, the product page should retain 6008-2RS1 rather than changing it to 6008-2RSH.

Internal Clearance

No internal-clearance suffix was provided with the original product identification.

A bearing marked 6008-2RSH/C3 represents a different internal-clearance variant from a standard-clearance 6008-2RSH.

For this reason, C3 should never be added or removed from the product designation for SEO purposes. The exact marking on the supplied SKF bearing must be retained.

Selection and Interchangeability

When selecting an equivalent for SKF 6008-2RSH, verify:

• 40 mm bore diameter
• 68 mm outside diameter
• 15 mm width
• single row deep groove ball bearing construction
• sealing configuration on both sides
• internal clearance
• load ratings
• speed requirements
• lubrication arrangement
• fits and operating conditions

A bearing from another manufacturer with the same 6008 and 40x68x15 mm dimensional designation should not automatically be considered fully interchangeable without checking its complete technical specification.

FAQ

What are the dimensions of SKF 6008-2RSH?

The bearing measures 40x68x15 mm: 40 mm bore diameter, 68 mm outside diameter and 15 mm width.

What type of bearing is SKF 6008-2RSH?

It is a single row deep groove ball bearing, one of the most widely used radial ball bearing constructions.

What does 2RSH mean on an SKF bearing?

2RSH means that the bearing has RSH contact seals on both sides.

Is SKF 6008-2RSH the same as 6008-2Z?

No. They have the same nominal dimensions, but 2RSH uses contact seals, while 2Z uses shields. Their operating characteristics therefore differ.

Can SKF 6008-2RSH carry axial loads?

Yes. Its deep groove construction allows it to support radial loads and axial loads acting in both directions.

What are the load ratings of SKF 6008?

The catalog values are C = 17.8 kN for the basic dynamic load rating and C0 = 11 kN for the basic static load rating.

Is 6008 2RS the official SKF designation?

2RS is commonly used as a generic commercial description. For SKF products, the exact suffix printed on the bearing or packaging, such as 2RSH or 2RS1, should be used for precise product identification.

Is SKF 6008-2RSH/C3 the same as 6008-2RSH?

No. C3 identifies increased internal radial clearance. If C3 is present on the bearing, it forms part of the technical designation and should not be omitted.
