Deep Groove Ball Bearings FAG 608 -2RSR
The FAG 608-2RSR single-row deep-groove ball bearing, with dimensions of 8x22x7 mm and contact seals on both sides, offers reliable protection for compact shaft guides.
The 608-2RSR deep groove ball bearing from FAG is a single-row miniature radial deep groove ball bearing made from standard 100Cr6 bearing steel. With a bore of 8 mm, an outside diameter of 22 mm and a width of 7 mm, this roller bearing primarily accommodates radial loads, but also handles axial forces in both directions. Featuring a dimensionally stable sheet steel cage and standard radial clearance, this design has proven its worth in compact mechanical assemblies as well as for quick repair work.
In which applications is the 608-2RSR deep groove ball bearing used?
Compact devices and precision mechanical units with limited installation space favour this bearing size for precise shaft guidance. The design accommodates radial forces and light axial guidance loads, such as those encountered in small drive units or rotating mechanisms. The operating temperature range is from –20 to +100 degrees Celsius, meaning this design is suitable for fluctuating ambient temperatures in both workshop and industrial environments. Manufacture to tolerance class P0/PN or ABEC 1 ensures a precise fit when replacing components.
What are the advantages of the double-sided 2RSR seal?
The designation 2RSR stands for double-sided abiding sealing discs that sit tightly against the inner ring. This design protects the interior from ingress of dust particles and splash water, whilst simultaneously retaining the grease fill within the bearing chamber. Unlike open bearings, there is no need for relubrication during operation, as the lubricant remains sealed inside. Thanks to the integrated sealing action, additional external covers are not required in most installation scenarios.
What are the key features of the 608-2RSR deep-groove ball bearing?
A single-row radial ball bearing from FAG with compact main dimensions: 8 mm internal width, 22 mm external width and 7 mm overall width. It is made from hardened 100Cr6 bearing steel and features a guided sheet steel cage. Two sliding seal discs protect the rolling elements from environmental influences, whilst the standard radial bearing clearance ensures smooth running.
What are the dimensions of the 608-2RSR deep-groove ball bearing?
The dimensions are exactly 8 mm for the internal diameter (shaft bore), 22 mm for the external diameter and 7 mm for the bearing width. The outer ring is cylindrical, with no flange or groove. These dimensions correspond to the globally standardised size 608 and facilitate a good fit in replacement and new designs.
What does the seal designation 2RSR mean in the context of FAG?
The abbreviation 2RSR denotes abiding contact seals fitted on both sides. The sealing lips rest against the inner ring with light pressure, forming a mechanical barrier against the ingress of dirt and splash water. At the same time, they prevent the grease from leaking out, which significantly extends the bearing’s service life in dusty environments.
What does the tolerance class P0 / ABEC 1 mean?
P0 refers to the standard tolerance for rolling bearings, which corresponds to ABEC Class 1 in the Anglo-American region. It defines the permissible deviations for bore diameter, outer diameter and concentricity. For standard requirements in mechanical engineering and drive technology, this tolerance class offers reliable precision at cost-effective manufacturing costs.
What is the operating temperature range of the bearing?
The bearing is designed for operating temperatures between -20 and +100 degrees Celsius. This temperature range is limited by the seal materials and the grease used. Within these limits, the sliding sealing lips retain their elasticity and the roller bearing steel retains its microstructural stability during continuous operation.
How does standard bearing clearance differ from C3?
Normal radial bearing clearance (often referred to as CN) describes the standard amount of movement between the balls and raceways when the bearing is unmounted. An increased bearing clearance, such as C3, is usually selected when significant temperature differences between the inner and outer rings occur during operation, or when tight press fits restrict the operating clearance. For standard applications, the standard clearance is sufficient.
