Bearing and Bearing Cart Replacement
If a cartridge bearing is found to be damaged or defective, it will need to be replaced.
This section deals with replacement of any bearing in the X or Y axis bearing carts.
There are 12 sealed cartridge bearings, 4 in each cart. The 4 bearings in the Y-axis
(vertical movement) bearing cart are all accessible without removing the entire cart from
the machine. The 2 rear bearings in each of the X-axis bearing carts are not readily
accessible, however. Removal of the carts, along with other components, is required in
order to replace any of the 4 rear bearings. Please make sure you read and understand
the procedure thoroughly before attempting this repair.
Y- Axis Bearing Replacement
1) Shut down the F-6100 computer
normally. Remove the P201 and P203
cables from the rear of the electronics
controller. This will prevent accidental
damage to electronic components from
manual movement of the gantry and
cutting head. Disconnect the main air
hose from the rear of the machine.
2) Remove 3 button-head Allen screws to
remove the cutting head cover plate
(1/8” Allen wrench). Disconnect the
motor cable and C-axis sensor cable
plugs, as shown. Remove the black and clear air hoses from their quick disconnect
couplings as well.
