Introduction
The shaft end of the driven machine shaft (material C60+N or higher strength) should con-
tain a hole centred in its end face as defined by DIN 332, form DS (with thread). The connec-
tion dimensions for the driven machine shaft can be found in the dimension drawing in the

WARNING
Risk of injury due to falling shrink disk or parts of the shrink disk
Injuries can be caused by the shrink disk falling or by flying fragments of the shrink disk.
Do not disassemble the shrink disk before you install it for the first time. Prevent the shrink
disk from slipping off the hollow shaft. If necessary, use suitable hoisting gear to lift and
transport the shrink disk. Arrange for qualified specialists to carry out the installation and
commissioning work.
