1) Insert eccentric nyt into nut hole. The eccentric nut can be easily inserted if fastened in the bearing bolt.

2) Frirst, gently fasten bearing bold and nut and fit the block into the rail. Then tentatively tighten eccentric part on the
    block

3) Take block out of the rail.

4) Tightten eccentric nut and bolt with the torque specified in the catalogue.

5) Try to fit the block in the rail

6) If any pressurem itert a tool into the eccentric nut and twist it counter-clockwise more than 90 degrees.

7) After fixing the eccentric part on the eccentric nut, tighten the nut and bolt again with the torque specified in the
    catalogue.

8) Fit the block on the rail.

9) Insert a tool into the eccentric nut and twist it clockwise adjusting the pressure. If the pressure adjusted overly,
    try step6) again. In case of block with more than 4 bearings, adjust 4th bearing as step^) above and adjust
    5th bearing in the same way.

10) Check that all the bearings run on the shaft faces.
