Heavy duty roller bearing

Overview:Heavy-duty needle roller bearings consist of a machined and ground channel-shaped outer ring with a complement of needle rollers retained and guided by a cage.

The high-strength cage retains and guides the rollers.An optional lubrication groove and hole in the outer ring facilitate relubrication.These bearings can be used with or without a machined and ground inner ring,depending on the suitability of the shaft as a raceway surface.

S izes:Metric:5 mm -175 mm bore (0.19685 in.-6.88976 in.).

Markets:Gear pumps,sheaves,automotive transmissions and two-cycle engines.

Features:Thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross section. Benefits:Optimum speed and lubrication-retention capability. Entity needle roller bearing(Heavy duty roller bearing) .NK,NKI,NA,NAV,NAO,HJ,BR,BRI
