The outer ring of BYB stamping outer ring needle roller bearing is precisely formed from thin steel plate, with small structural space and large load capacity. Suitable for occasions where installation space is limited and housing holes are not suitable as raceways. Further axial positioning is not necessary after pressing into the seat hole. This type of needle roller bearing generally does not use an inner ring. If an inner ring is required, it can be selected from a sample. Compared to the perforated stamped outer ring needle roller bearing, the sealed stamped outer ring needle roller bearing is extremely effective in sealing the shaft end bearing area. The long-term use temperature of grease lubricated needle roller bearings is - 20 ℃~120 ℃.
