Detailed Product Description

For the universal joints of commercial vehicle propeller shafts, we has developed specific cold forged cup needle roller bearings with a closed end. Their main advantages include:

The thin-walled, case-hardened cup enables the use of relatively large diameter rollers to provide high load carrying capacity while still maintaining a compact bearing arrangement. An optimum load distribution over the rollers is achieved by a special contact profile and ground raceways. The integral polymer thrust washer and the special design of the cup bottom enable good damping of axial shock loads and axial load carrying capacity without the risk of rupturing the closed cup end.

The spring washer between the roller ends and seal reduces the risk of false brinelling as it aligns the rollers in the unloaded zone and causes the roller complement to continue rotating.

Each universal joint bearing is efficiently protected by two seals made of acrylonitrile-butadiene rubber (NBR). A steel reinforced outer seal protects against coarse contaminants. A modified radial shaft seal prevents the ingress of dirt and water while retaining the grease in the bearing. All universal joint bearings are lubricated for life. However, relubrication is possible. For extremely harsh operating conditions, recommends using Shell Retinax LX2 grease for relubrication.

Universal joint bearings are suitable for temperatures ranging from 25
