Needle roller bearings with an outer ring of precision stamping of sheet steel, and cage and needle the entire group, whose radial cross-sectional thickness is very small, and has a large load capacity, especially suitable for the requirements of the economy high-volume products.
Kind of needle bearing outer ring and bearing housing interference fit, no axial fixtures. Even at high speed, high load conditions, but also to ensure their effective performance. In addition, due to the volume of seal fat, can ensure long lubrication intervals. Typically, single row Needle roller bearings without lubrication hole and then double row bearings with lubrication holes.
This class generally do not have an inner ring needle roller bearings. If you need to use the inner ring, the choice of IR-type inner.
Needle roller bearings into the bearing ends of perforation (HK-type) and closed end bearings (BK-type). Compared with perforation drawn cup needle roller bearings, bearing the seal one end of the closed type, suitable for shaft end and can withstand small axial travel power.
