ROEMHELD PCC Concentric Hydraulic Vise, H4400

ROEMHELD Precision Vises

Product Information

The housings of the concentric PCC vises are square in design, which allows for the installation of a large-diameter clamping piston. This design provides exceptionally high clamping force in the pneumatic version. The piston force is transmitted without backlash to both base jaws, moving them synchronously and concentrically. All concentric vises include an internal flow-rate limiter.

Here’s a few additional things you need to know about the PCC

It’s compact & powerful – It’s low profile and wide base results in ultimate rigidity & clamping force up to 4000 lbs.

It’s extremely precise – Confidently position parts to center with ±5 microns repeatability.

It’s very accessible – With its high clamping point and sloped base you get great access to all 5 sides and excellent chip flow.

It’s ideal for automation – With features like ID/OD clamping, automatic lubrication, part and position sensing and quick-change jaws, giving you a worry-free process.

Application Information

These pneumatic or hydraulic operated concentric vises position and clamp workpieces with an accuracy of ±0.005 mm. They are ideal for high-volume production of precision parts in both single- and multi-clamp fixtures. The double-acting cylinder allows for both internal and external clamping of workpieces.
