Deep Groove Ball Bearings FAG 62204 -2RSR

The FAG 62204 -2RSR deep-groove ball bearing, measuring 20x47x18 mm, offers a spacious internal chamber and protection against dirt particles on both sides.

The 62204 -2RSR deep groove ball bearing is a single-row rolling bearing designed for combined radial and axial loads. Compared to standard bearings with the same bore, this version has an increased width of 18 mm. Manufactured from standard rolling-element bearing steel 100Cr6, the design features a sheet steel cage and standard radial clearance. The bearing operates reliably within a temperature range of -20 to +100 degrees Celsius. It is manufactured to tolerance class P0 or ABEC 1.

What is the 62204-2RSR deep groove ball bearing suitable for in operation?

Design engineers and maintenance technicians prefer to use this design where, in addition to radial load-bearing capacity, reliable protection against environmental influences is required. Typical applications include shaft bearings in general mechanical engineering subject to combined loads. Thanks to the seals that seal on both sides, the lubricant remains trapped inside the bearing, whilst dirt particles and moisture are prevented from reaching the raceways. The cylindrical outer ring, without a flange or groove, fits precisely into standardised housing bores.

What advantages does the 2RSR seal offer over open variants?

The designation 2RSR stands for two sealing discs that make contact on both sides. These sealing lips make contact with the inner ring and help to reduce the ingress of particles and moisture. Unlike open bearings, there is no need for additional external sealing elements. When designing the bearing, the circumferential speed of the sealing lip and the permissible temperature range must be taken into account. In conjunction with the standard radial bearing clearance, the bearing runs stably on shafts with a diameter of 20 mm.
