Live centers

Drop-forged shank made of hardened steel. Rotating point made of through-hardened, alloy steel. Four-point support for high axial and radial loads. Concentricity 0.005 mm or better. High speeds of 10 000 RPMs. Double labyrinth seal design. No maintenance up to 2000 hours and longer service life due to lifetime lubrication of the roller bearings. These live centers are designed for CNC machine tools and copying lathes with hydraulic tail -stocks as well as for machining workpieces with small center holes, and precision machining at ultrahigh speeds.

The drop-forged hardened steel shank, tapered at the front, is highly practical and accessible for all lathe work. The heavy-duty center made of high-tensile, wear-resistant alloy steel is through-hardened and can be reground as required. To achieve greater stability and maximum rigidity the rotating center is supported by front and rear bearings. Because of the large number of rollers with low relative velocity, these precision bearings are equally suited to both high-speed operations and heavy duty applications. The pressure relief automatically compensates any thermal expansion of the workpiece during the machining process. This feature protects the bearings in the live center as well as the machine bearings.

GF-type centers are special designed with fixed point and a bearing-mounted
rotating head. The radial and axial loads are absorbed by several heavyduty, adjustable roller bearings. They supplement the DA-series for workpieces with even larger bores. Unlike the other types, the GF center is only supplied with an angle of 75°
