Deep Groove Ball Bearings FAG 63004 -2RSR

The FAG 63004 -2RSR deep-groove ball bearing, measuring 20x42x16 mm and featuring contact seals on both sides, offers effective protection against dust and moisture.

The 63004 -2RSR deep groove ball bearing is a single-row rolling bearing made from standard bearing steel (100Cr6) with a cylindrical bore. This FAG design primarily accommodates radial loads and supports shafts with a 20 mm diameter within the housing. Thanks to its sealed construction, the bearing is suitable for applications where dirt particles or splash water need to be kept out. The integrated sheet steel cage guides the rolling elements in an orderly manner within the raceway system.

In which applications is the 63004-2RSR deep groove ball bearing used?

This radial ball bearing is used to support rotating shafts subjected to predominantly radial forces and low axial loads. As the RSR sealing lips bear against the inner ring on both sides with a sliding fit, the ingress of dirt and moisture into the bearing interior is reduced. The design is intended for bearing locations where low-maintenance operation at stable speeds is required and no external relubrication takes place.

What features does the 2RSR seal offer on this rolling bearing?

The designator 2RSR denotes two sliding seal discs that shield the internal space on both sides against dust and moisture. Compared with non-contacting cover plates, the sliding sealing lip generates low frictional resistance whilst protecting the raceways from premature wear caused by foreign particles. In conjunction with the standard radial bearing clearance, the design covers a thermal operating range from -20 to +100 degrees Celsius.
