Such needle roller bearings in general do not have the inner ring. If the need to use the inner ring, the choice of IR-type inner circle.
HT ram into the outer ring bearing needle roller bearings at both ends of piercing (HK-type) and bearing one end closed (BK-type). Stamping and perforation of the outer ring needle roller bearings compared to the sealed-bearing for the closed end, apply to shaft and affordable small Axial momentum.

Sealed with a needle roller bearings stamping outer ring Sealing, in the general working conditions, to protect the bearings and grease from the debris penetrated leakage. Therefore, using the temperature of -20 ℃ -120 ℃ within the scope of the long-term operation. If the appropriate time to add grease or short-term use, can be used to +130 ℃.
A ring made of synthetic rubber, lip good elasticity, and lined with steel-core, mechanical rigidity strong addition, the ring set up to maintain the axial guiding role.

If there is any question of stamped cup needle roller bearings. Welcome to contact us in details.
