Closed end drawn cup needle roller bearing BK3512
Needle roller bearings have a high load carrying capacity in addition to their low corss-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited. Because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.
