Product Description

Hydraulic self-centering steady rest, not only can ensure automatic centering, but also can make the roundness and coaxiality of the turned or ground workpiece reach higher precision, so that the machine tool can achieve more reliable, stable, efficient, and high-efficiency Precision machining.

Internal centralized lubrication: lubricating interval is 2 to 5 minutes

Lubricating pressure range: 10-45 bar

Lubricating oil: HLP 46 DIN51502
