Description
This combined needle roller bearing carries radial load through a needle roller set and axial load in a single direction through an integrated axial ball bearing component, built to DIN 5429 without an end cap. Bore diameter is 12.0 mm, outside diameter 21.0 mm, height 23.0 mm, net mass 39.54 g, and the limiting speed reaches 11000 1/min. The cage is of standard design. The unit is designed for oil lubrication and has no sealing, so an external sealing arrangement in the housing is required to keep the lubricant in and contaminants out. Combining radial and single-direction axial support in one compact design allows a shorter axial installation length compared to using separate bearings for each load direction, suitable where both radial and one-way axial loads act on the same shaft position.
