Bimba Ultra Slide Rodless Cylinder - Manual (Page 3)

Note: The Ultran guide shaft bearings were upgraded in the second half of
2000. All new repair kits shipped after September 2000 will contain the new
style shaft bearings, which utilize internal press rings. If the Ultran assembly
being repaired does not have internal press rings, be sure to add them before
pressing the bearings in place.

Refer to Figure 4 for Steps 18–21
18. Remove the piston from the body.
19. Using cutters, cut the seal and pull it out of the groove. Be careful not to scratch
the surfaces of the groove.
20. The new piston bearing configuration is non–repairable. If the Ultran being
repaired has split piston bearings, it should be sent to the factory for new style
piston bearings, or a new piston assembly should be ordered. Contact your
distributor for details.
21. Using the same insertion tool as Step 13, slip the seal into its groove. Be sure
the seal is oriented so the lip faces away from the bearing.
Refer to Figure 5 for Step 22
22. Place the piston on top of the carriage and note its position. The ends of the
piston should extend beyond the ends of the carriage equally. If they do not,
turn the piston end for end. This orientation of the piston and carriage must be
maintained for the rest of the assembly.
