Machined Needle Roller Bearing w/o Inner Ring Poly Cage (NK.TN)

• NK, needle roller bearing without inner ring, lube hole in outer ring.
• TN, molded cage of reinforced polymer.

About Heavy-Duty Needle Roller Bearings

• Heavy-duty needle roller bearings consist of a machined and ground channel-shaped outer ring with a complement of needle rollers, and a cage.
• The high-strength cage retains and guides the rollers. An optional lubrication groove and hole in the outer ring facilitates re-lubrication.
• 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.

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.
