NA4905 thrust needle roller bearing

The needle roller bearings are roller bearings with cylindrical rollers that are long and thin in relation to their diameter. In spite of their low cross section, needle roller bearings have a high load carrying capacity and are therefore extremely suitable for bearing arrangements where radial space is limited.

Feature

Drawn cup needle roller bearing for applications with high dynamic loads

• Drawn steel outer shell (cup) has a reduced cross-section for use in restricted spaces
• Steel cage guides and evenly spaces rollers for reduced friction, vibration, and noise
• Through-hardened, high-carbon chromium steel rollers for heat tolerance and durability under heavy loads

Application

Automotive transmissions, air-conditioner compressors, bulldozer blades, overhead traveling cranes, gearboxes, machine tool spindles, copying machines and so on.
