motorizedhydrostaticISO

Product description
Unlike motor-driven grinding spindles, the DYFJM-125(065)15/5.5-X is a driven hydrostatic tailstock spindle engineered to provide reliable secondary support and high-precision alignment of workpieces on machine tools. It supports bidirectional rotation, features very low radial and axial runout, and is rated at 1300 rpm (maximum 1500 rpm). Installation diameter is 125 mm and journal diameter is Φ65 mm.
