In the ELGA-BS-KF-150, two buffers each are inserted into the slide module on
each front side.
4.5.2.1 Replacing the buffers which touch the bearing block
1. Do not push the slide module up to the stop in the direction of the bearing
block, leave approx. 5 cm space.
2. Undo the cover band in the bearing block and in the bearing cap
(  Chapter 4.3.1 on page 21 ).


Chapter 4.3.2 on page 22 ).
4. Unscrew the socket head screws from the bearing block (  Chapter 4.3.2

Note
The recirculating ball bearing guide system of the roller carriages is
preloaded. Therefore, if the roller carriages are not pushed off the roller track
carefully, individual balls can easily spring out and be lost.
Any ball bearings that spring out of the roller carriages must be re-inserted.
5. Push the spindle assembly with slide module and bearing block onto the
roller track at the front end of the cylinder barrel – the roller carriages must
remain on the roller track.
