Hainbuch clamping cylinders

Energy-efficient clamping cylinders are the latest addition to the Hainbuch range.
The range takes in normal pressure, high pressure, and bearingless high pressure clamping cylinders.

They feature a patented rotary feed, with self-regulating flat-gap seal, that ensures approximately 50 per cent less leakage, compared to conventional clamping cylinders. Due to the low leakage, a small hydraulic aggregate is all that is required, while less energy is wasted.

With the high-pressure cylinders, users profit from shorter cycle times, higher productivity, and lower energy costs. The reduced oil volume ensures fast clamping strokes, the reduced mass allows the spindles to accelerate and brake faster, and th machine drives have a longer life-span.

The standard cylinders, with up to 80 bar, are ideal for machines with a small overall size. They offer a greater clamping pressure regulating range and thus enable more sensitive clamping. Differential pressure clamping is even available as an option.

The highlight of the clamping cylinder product line is the slim-line, high pressure clamping cylinder without ball bearings, says the company.

Maximum spindle concentricity, higher machine accuracy, long life time, and higher RPM are the claimed benefit.
