Product Details

Needle roller one way bearing NKIB5904 / Angular Contact Combination Bearing

Notes:

Combined needle roller bearings consist of a radial needle roller bearing combined with a thrust bearing and are consequently able to accommodate both radial and axial loads. Combined needle roller bearings provide the means to produce locating bearing arrangements where radial space is limited"
