Overview

Drawn cup needle roller bearing with a closed end

Drawn cup needle roller bearings are typically used in applications where the housing bore cannot be used as a raceway for a needle roller and cage assembly, but where a very compact and economical bearing arrangement is required. Owing to the large number of rollers, the bearings have a high load carrying capacity and stiffness. The closed end makes them suitable for bearing arrangements where they are situated at the end of a shaft.

Key features

High radial load carrying capacity
Accommodate small axial guidance forces
High stiffness
Very low cross-sectional height

Typical applications

Automotive transmissions
Industrial gearboxes
Compressors and pumps
Links, pivots, and rocker arms

Selection guidance

Check mounting envelope, inner ring requirement, shaft surface hardness, lubrication, load, and speed range.
