Duro-T key bar chuck Only quality is cost-effective in the long run

Highest clamping force, absolute precision, high user-friendliness and a completely surface-hardened, extraordinarily rigid chuck body: They are the characteristics of the Duro-T key bar chuck from the clamping experts of RÖHM. The Duro-T can be used universally thanks to its through-hole. Hence, not only can flange-like workpieces be clamped and machined, but also bars. The perfect all-rounder for industry and trade.

Like always, RÖHM has its focus on practical everyday use. Turning, replacing and moving the clamping jaws only takes a few seconds thanks to the RÖHM jaws quick-change system. Clear economic advantage: the minimal tooling times lead to time and hence cost savings. Due to the visible markings for the jaws quick adjustment, the right position can be seen quickly during a change.

To make sure that as little coolant as possible gets into the machine spindle area from the front side, the external shape including the water spray edge was redesigned thereby also meeting the needs in practice. Other well thought out details ensure longevity. For example, the corrosion protection was improved, the greasing possibilities of heavily used sliding surfaces were modified, and the safety lock valve was revised. The key bar principle provides a constantly high clamping force and very good centrifugal force behaviour, The radial and axial run-out tolerance is twice as accurate as specified by DIN accuracy class 1. Specifically for size 250, this means that where the DIN standard calls for accuracy of 0.06mm, the Duro-T provides 0.03 mm.

With the sealed version, Duro-TA, the clamping device specialist has a key bar chuck in a sealed design in its product range, which is specifically suited for use on grinding machines.

In short, The Duro-T comes with everything that is needed in practice: easy jaw quickchange, very high clamping forces, above-average accuracy and longevity.
