Description
This combined needle roller bearing carries radial load through the needle roller set and axial load in one direction through the integrated axial ball bearing component, built to DIN 5429 with an end cap. Bore diameter is 40.0 mm, outside diameter 52.0 mm, height 32.0 mm, net mass 218.89 g, and the limiting speed reaches 4000 1/min. The cage is of standard design. The Z sealing on both sides retains grease inside the bearing and keeps out contamination, making it suitable for grease lubrication without additional external sealing elements. Combining radial and single-direction axial support in one compact unit allows shaft length and housing bore to be reduced compared to using separate bearings, provided axial load acts only in the supported direction.
