We recommend the following specialist combined roller bearing units are only used for replacement parts.


This JC unit offers the ability to pre-load the bearings and hence reduce the play between the bearings and the rails. The combined roller bearing should be positioned so that is carrying the main force and the smaller adjustable bearing should located against the opposite flange with a clearance of 0.1mm. Whilst the Hertzian pressure remains the same as the 4.061, it is best to avoid high loads to minimise wear on the profile. When the bearing is adjusted, it is important to ensure the unit runs smoothly along the whole length of the rail. Click the technical drawing to enlarge.
