3.7.2 Hollow shaft with shrink disc element (option: S)
NOTICE!
Risk of damage to the gear unit if the shrink disk is installed incorrectly
• To avoid tension or rubbing between the hollow shaft and the shoulder, hollow shafts with shrink
discs must not be mounted on solid machine shafts with shoulders.
• If the tensioning bolts of the shrink disc are tightened without the solid shaft inserted, the hollow
shaft may be permanently deformed. Do not tighten the bolts if the solid shaft is not inserted!
• When re-assembling the shrink disc, the thread and head surfaces of the tensioning bolts must be
treated with grease which does not contain Molycote.
• The separate manufacturer’s documentation for the shrink disc must be observed for installation.
Unless otherwise stated in the specific dimension sheet for the order, the external diameter of the
customer's shaft must have a fit of h6 if the diameter is up to and including 160 mm or g6 for larger
diameters. The fit must be according to DIN EN ISO 286.
The material of the customer's shaft must have a minimum yield strength of 360 N/mm

. This ensures
that no permanent deformation occurs due to the clamping force.
