Needle roller bearings are radially low-bearing, very viable rolling bearings, which are used as a floating bearing and belong to the group of radial needle roller bearings. These bearings consist of solid outer rings, needle rings and removable inner rings; that is, they can be supplied according to the application with or without inner ring. The bearing rings are not like the outer sleeves of the needle sleeves and needle bushes pulled without cutting, but machined. Due to their non-locating function, the bearings can not guide the shaft axially in any direction.
