Lathe chucks, hand operated

Key bar chucks with quick-acting jaw change system

The RÖHM key bar chucks with quick jaw change system convince in two ways. On the one hand the jaws can be quickly and easily turned, changed or offset over the entire clamping range within a few seconds. On the other the key bar chucks convince with maximum clamping forces and maximum accurancy thanks to direct force transfer via the key bar system. Large, straight surfaces transmitting the force from the key bar to the jaw teeth guarantee long life and produce a very high clamping force combined with an accurancy which is twice high as required by DIN 6386. The high clamping force is achieved without much physical effort by manually turning the key.

ADVANTAGES AT A GLANCE
- Maximum clamping forces thanks to direct force transfer via the key bar system
- Maximum concentricity and axial run-out tolerance
- High user-friendliness thanks to quick jaw change system

DURO-T key bar chucks are successfully used wherever extremely high tension forces, high concentric accuracy and reliable continuous repeatability are needed.
For lathes. Suitable for milling machines, dividing attachments and machining centres in connection with a base plate, non rotating.


The jaws can be quickly and easily reversed, exchanged or relocated over the entire gripping range.
The jaws retain their accuracy if they are always used on the same chuck and when base jaws and top jaws are kept screwed together as a matched set for recurring work. It is therefore advisable to stock several jaw sets.

Geared scroll chucks
Proven chuck with spiral ring
The RÖHM geared scroll chucks have already been in use for decades and have proven themselves a thousand times
over. The jaws can be quickly adjusted over the entire clamping range by means of the spiral ring. Using the radially
arranged drive, the force is transferred to the hardened spiral ring via a bevel gearing and further conducted to the
clamping jaws via the spiral.

The RÖHM geared scroll chucks have proven themselves a thousand times over and have already
been used successfully on lathes, rotary tables and dividing attachments for decades. The jaws can
be adjusted over the entire clamping range in order to be able to very quickly clamp workpieces with
a wide clamping diameter range without offsetting the jaws.

Advantage at a glance
•Quick jaw adjustment over the entire clamping range
•Proven chuck with optimal price/performance ratio
•Protection of the machine spindle by means of splash-water edge
