Product Parameters

Drawn Cup Needle Roller Bearings
Drawn cup needle roller bearings are needle roller bearings with a deep drawn, thin-walled outer ring with either open ends
or a closed end.
They are characterized by a very low sectional height and high load carrying capacity. 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.
