Live centers

For counter-clamping workpieces on turning and grinding machines with max. 0.005 mm concentricity deviation

The requirement for high cutting capacities and high working precision demands additional support by a live center for many workpieces due to their shape and length. Thanks to their precision bearings, RÖHM live centers offer optimal force absorption and a maximum concentricity deviation of up to 0.005 mm. The center points are maintenance-free thanks to the lifetime lubrication.

 

1: Shank hole for easy exchange of the center point

2: Precision roller and needle bearings for maximum concentricity with long service life

3: Center point with wear-resistant, hard-metal insert, can be reground multiple times, and shank mounted

4: Lip seal and additional water spray groove as protection against penetration of cooling lubricants

5: Solid supporting surface on the axial bearing for full loading capacity

6: Ground shank, true to gauge according to DIN 228 AT5 for tight tolerance and maximum concentricity
