Deep Groove Ball Bearings FAG 6008 -2RSR-C3

The FAG 6008 -2RSR-C3 deep groove ball bearing, measuring 40x68x15 mm, with contact seals on both sides and a C3 radial clearance, offers protection against dirt at elevated operating temperatures.

This single-row deep-groove ball bearing 6008 -2RSR-C3 is manufactured by FAG Wälzlager and is made from standard rolling-element bearing steel (100Cr6). As a versatile rolling bearing, the design primarily absorbs radial forces, whilst also guiding shafts stably under axial loads in both directions. This version features a cylindrical outer ring without a groove or flange. Thanks to the factory-fitted sliding seals, the lubricant remains protected inside the bearing.

What is the 6008-2RSR-C3 deep groove ball bearing suitable for in operation?

Design engineers and maintenance personnel use this design in machine components where foreign particles and moisture must be kept away from the raceways. The bearing is suitable for rotating shafts in mechanical and plant engineering at normal to elevated temperatures. Thanks to the C3 clearance, the component can accommodate thermal expansion, whilst the sliding seals retain the grease within the rolling chamber.

The specified operating temperature range is from -20 to +100 degrees. The integrated sheet steel cage maintains an even spacing between the rolling elements and guides them securely within the raceway. The sealed design reduces maintenance requirements, as no external relubrication is necessary.

What do the designations 2RSR and C3 mean for your bearing selection?

The designation 2RSR stands for grinding seal lips fitted on both sides, which come into direct contact with the inner ring and make it difficult for dirt to penetrate. The suffix C3 indicates a slightly increased radial clearance. This combination is recommended when the shaft and inner ring heat up more than the housing during operation, or when tight fits are used.

The expansion of the inner ring reduces the radial operating clearance without causing the balls to become stressed. At the same time, the contact seals provide an effective barrier against environmental influences.
