Roemheld (UK) has introduced the B 1.8270, a compact hydraulically operated workholding clamp designed to secure workpieces and fixtures in tight spaces with high, consistent clamping force.
The product is particularly suitable for clamping castings, dies, moulds, and fixtures before metal cutting, especially when narrow grooves, recesses, or pockets restrict access. Its patented kinematic design sets it apart from conventional swing or rotating clamps: the clamping lever initially moves horizontally towards the target point, then shifts vertically downward to complete the process — allowing for precise, space-efficient clamping that was previously difficult or very complex to achieve.
At a maximum operating pressure of 220 bar, the unit delivers 6.5kN of clamping force over a horizontal stroke of 8mm, with a vertical clamping stroke of up to 4mm. The latter accommodates slight dimensional variation across a batch of workpieces. The low-profile, plug-in design eliminates the need for external piping, and optional pneumatic position monitoring confirms whether it is clamped or unclamped for automated production environments.
Constructed from hardened stainless steel with nitrile butadiene rubber and polyurethane seals, the clamp is rated to 80°C. Multiple lever configurations are available, with a quick-change mechanism allowing easy adaptation between workholding tasks.
