The Bosch Rexroth R151241012 (type ZEM-E-S 40x5Rx3,5-5) is a genuine ball screw nut with 40 mm, 5 mm right-hand, 34,900 N. RendatSP supplies it new and original, ready to ship worldwide.
Rexroth ball screw assemblies convert rotary motion into precise linear motion on CNC machines, injection moulding machines and automation axes. When a nut wears or loses preload, positioning accuracy drops; an identical replacement nut by material number restores the original diameter, lead, ball size and flange pattern.
