Support roller bearings generally consist of four major components: 1. a machined thick-walled outer ring; 2. needle rollers or cylindrical rollers; 3. a cage raceway; and 4. an inner ring or bolts and seals.
The support roller bearings (NA22 series) are double-sealed on both sides but do not include an inner ring.
