NAXR15 KOYO NEEDLE ROLLER BEARINGS

KOYO Combined bearings consist of a radial bearing (needle roller bearing) and a thrust bearing (ball, roller or needle bearing). The thrust roller bearing is usually a cylindrical roller thrust bearing.
Combined bearings make an effective alternative in place of two separate bearings – in terms of cost, handling and packaging. Combined bearings can be used with or without matching inner rings and thrust washers – though these are listed opposite the bearing part numbers, where possible, on the following pages of tables for convenience.
