machined needle roller bearings

Product Description

Machined needle roller bearings have a machined and ground channel-shaped outer ring with a complement of needle rollers retained and guided by a cage. The thick outer ring provides maximum load capacity and shock resistance with a relatively small radial cross section. With the high-strength cage retaining and guiding the rollers, this design provides high speed and lubrication retention capability. A lubrication groove and hole in the O.D. facilitate lubrication through the outer ring. 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. Size range: 5 mm - **0 mm (0.**5 in. - 9.*5 in.) bore Design Attributes： High-strength cage retains and guides rollers High speed and lubrication-retention capability. A lubrication groove and hole in the O.D. facilitate lubrication through the outer ring. Bearings can be used with or without a machined and ground inner ring depending on the suitability of the shaft as a raceway surface. Applications： Gear pumps Sheaves Automotive transmissions Two-cycle engines
