Mounting

Alignment needle roller bearings should be pressed into the housing bore using a mounting dolly (fig. 1). An O-ring provides a simple means of retaining the bearing on the mounting dolly. The stamped side (side face with the designation) should abut the flange of the mounting dolly.
Special care should be taken to prevent the sleeve from skewing or tilting when it is being pressed into the housing. Otherwise the rollers and raceways could easily be damaged.
For grease lubricated bearings, the bearing should be lubricated prior to mounting.
