Needle roller bearings RNA4822

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.

Detailed Description:
1. Series: HK, BK, NK, RNA, RNAO, RPNA and so on
2. The bearings are available in different design and a wide range of sizes, which are appropriate for different applications
3. Design: With open ends or closed ends, with or without inner ring, with or without flanges, full complement and so on
4. Types: Needle roller cage cage assemblies, drawn cup needle roller bearings, needle roller bearings with machined rings, alignment needle roller bearings, combined needle roller bearings, and so on
5. Typical Applications: Automotive transmissions, air-conditioner compressors, bulldozer blades, overhead traveling cranes, gearboxes, machine tool spindles, copying machines and so on.

Bearing Features:
* Rollers that are three to ten times longer than their diameter
* Low cross section
* relatively large radial load capability
* Different design and a wide range of size
* Widespread use.
