   ZGU-ZSU heavy Geared scroll chucks


The spiral ring chuck - a proven and universal
suitable clamping system - finds it´s application
wherever a high Clamping force, high runout
accuracy and very high repeatability are
required.  (e.g. lathes, turntables, circular indexing tables, etc.).

Cross tenon to ISO 3442 and ASA B 5.8.

The jaws can be moved across the entire clamping range by turning a key.  Due to
this, workpieces with different diameters can be clamped without changing or shifting
the jaws.  Heavy design with large through-hole.

Technical features:
•  with base jaws and reversible top jaws, with scroll
•  self-centering
•  lathe chucks must be lubricated regularly to maintain their grippng force

Delivery includes:
1 set of base jaws (GB),
1 set of reversible top jaws (UB),
1 operating key, mounting bolts
