We are a factory specializing in the production of high-quality NKIB 5908 Combined needle roller bearings. Contact us for reliable and durable bearings.
These combined bearings: consist of a radial needle roller bearing and an angular contact ball bearing accommodate heavy radial loads, carried exclusively by the needle roller bearing accommodate light axial loads, carried exclusively by the angular contact ball bearing are low cross section bearings can operate at high speeds are separable, i.e. the inner ring can be mounted separately from the outer ring and rolling element and cage assemblies can be grease or oil lubricated, depending on the application In the case of grease lubrication, both the needle roller and angular contact ball bearings should be filled with the same lubricant prior to mounting. NKIB series bearings: can locate the shaft in both directions have axial clearance, between 0,08 and 0,25 mm have a two-piece inner ring to facilitate mounting When mounting the inner ring, it is important that the two pieces are axially clamped to one another have inner rings, which are not interchangeable with those from another seemingly identical bearing
