material
L (length of toothed belt in mm) = Multiplier “A” × ( 2 × stroke r value “B”)
L = 1,0× (600 + 2 × 20 + 405) mm
L = 1.045 mm
rounded down to an integer multiple of the pitch “C” (in this example: 5)
L = 1.044 mm
5.1 Replacing the toothed belt
On replacing the toothed belt due to long operation, it is useful to replace the toothed belt pulley module including deep-
groove ball bearings at the same time (
 Chapter 5.2 on page 32 and  Chapter 5.3 on page 33 ).
Ideally, the new toothed belt can be threaded in, without dismantling the roller and toothed belt pulley module first.
5.1.1 Removing the toothed belt
1. Loosen the socket head screws of the clamps  toothed belt is
tension-free.
– In the case of ELCC-TB-KF-60 / 70, the clamping plate is pressed into the
clamping component module by one grub screw.
– In the case of ELCC-TB-KF-90 / 110, the clamping plate is pressed into the
clamping component module by two grub screws.
2. Unscrew the grub screws (2x) or (4x) from the clamping component
modules (2x).
