Needle Bearings

Needle Bearings are roller bearings with cylindrical rollers which are thin and long in relation to their diameter. They are referred to as Needle Rollers. In spite of their low cross section, the bearings have a high load carrying capacity and are thus eminently suitable for bearing arrangements where radial space is limited.

The needle rollers have a profile which is slightle relieved towards the roller ends. The resultant modified line contact between needle rollers and raceways means that damaging edge stresses are avoided.
