SKF 608 Bearing Dimensions

The principal dimensions of the SKF 608-2RSH are:

d = 8 mm - bore diameter
D = 22 mm - outside diameter
B = 7 mm - bearing width

The 8x22x7 mm size is widely used in compact rotating mechanisms.

When selecting a replacement, however, dimensions alone are not sufficient. The seal design, internal clearance, speed, load and operating environment should also be verified.

What Does SKF 608-2RSH Mean?

The designation contains important information about the bearing.

608 identifies the deep groove ball bearing size with principal dimensions of 8x22x7 mm.

2RSH indicates contact seals on both sides of the bearing.

The seals help:

• reduce the ingress of contaminants
• protect the raceways and rolling elements
• retain lubricant inside the bearing
• reduce maintenance requirements

SKF identifies this product as a single-row deep groove ball bearing with contact seals on both sides.

SKF 608 2RS or SKF 608-2RSH?

608 2RS is a widely used generic commercial description for a 608 bearing sealed on both sides.

For this specific SKF product, the proper manufacturer designation is:

SKF 608-2RSH

Customers may therefore search for the same type of product using phrases such as SKF 608 2RS, 608 2RS SKF, SKF 608 2RS 8x22x7 or sealed 608 bearing, while the SKF designation should be used when precise product identification is required.

SKF 608 Deep Groove Ball Bearing Design

The SKF 608-2RSH belongs to the family of single-row deep groove ball bearings.

Deep raceway grooves enable this bearing design to accommodate primarily radial loads, while also allowing appropriate axial loads in both directions.

Deep groove ball bearings are among the most widely used rolling bearing designs because they combine:

• relatively low friction
• compact construction
• suitability for high rotational speeds
• radial load capability
• axial load capability in both directions
• broad application versatility

SKF 608-2RSH vs SKF 608-2Z

Both versions have the same principal dimensions of 8x22x7 mm, but the closure design is different.

SKF 608-2RSH uses contact seals on both sides. This design provides enhanced protection against contamination.

SKF 608-2Z uses metal shields on both sides. Shielded designs generally provide lower friction but a different level of protection against external contamination.

The choice between 608-2RSH and 608-2Z should therefore be based on operating speed, contamination, moisture and the required level of protection.

Applications of SKF 608-2RSH 8x22x7

The SKF 608-2RSH can be used in appropriately designed:

• electric motors
• rollers and guide rollers
• small drive systems
• industrial automation
• power tools
• fans
• technical equipment
• industrial machinery
• compact rotating mechanisms

Actual suitability should always be verified according to load, speed, temperature, fits and other operating conditions.

SKF 608-2RSH Load Ratings

For the 608 bearing size, SKF specifies:

Basic Dynamic Load Rating C: 3.45 kN

Basic Static Load Rating C0: 1.37 kN

The basic dynamic load rating is an important parameter used in bearing life calculations under rotating load conditions.

The basic static load rating relates to bearing performance under static or very slowly rotating loading conditions.

SKF 608-2RSH Speed

For the sealed SKF 608-2RSH, SKF specifies a limiting speed of 22,000 r/min.

This does not mean that 22,000 r/min is automatically suitable for every application. Actual permissible operating speed also depends on load, temperature, fits, lubrication and the design of the complete bearing arrangement.

Factory Lubricated Sealed Bearing

SKF 608-2RSH is supplied as a grease-lubricated sealed bearing.

The seals help retain lubricant within the bearing while protecting the internal components against external contamination.

This makes sealed deep groove ball bearings particularly practical in applications where frequent relubrication would be inconvenient or unnecessary.

How to Select a 608 8x22x7 Bearing

Before replacing a bearing, verify:

Designation: 608
Dimensions: 8x22x7 mm
Bore: 8 mm
Outside Diameter: 22 mm
Width: 7 mm
Closure: 2RSH contact seals
Internal Clearance: CN / Normal
Load: suitable for the application
Speed: suitable for operating conditions
Temperature: within the permitted operating range

Two bearings with identical 8x22x7 mm dimensions are not necessarily fully interchangeable if their seals, internal clearance or other design characteristics differ.

Operational Advantages

• Original SKF bearing.
• Standard 8x22x7 mm dimensions.
• Contact seals on both sides.
• Factory grease lubrication.
• Normal CN internal clearance.
• Compact single-row deep groove design.

SKF 608-2RSH for Industry and MRO

The SKF 608-2RSH is suitable for both original machine construction and replacement requirements.

Typical customers include:

• industrial maintenance departments
• MRO organizations
• manufacturing plants
• machine manufacturers
• technical service companies
• repair workshops
• industrial distributors
• B2B customers

Its compact dimensions and standardized 608 design make it particularly relevant for maintenance and replacement applications involving smaller rotating equipment.
