FAQ

When fitting SFERAX ball bearings, extreme care should be taken (just as for radial bearings).
For best results and to ensure precise fitting, the bearing should be pressed into the housing using a mandrel 0,1 mm smaller than the housing bore. It should be square to the bearing and in contact with the outer housing only (see illustration 1). The ball bearing can be held in place by being slightly tightened without hold or left to slide freely and fastened by screw nut, circlips, end cover, etc. It can also be bonded (see product sheet).

Where two ball bearings are to be used in tandem, it is recommended that the shaft be inserted into the ball bearings prior to bonding in place.
