RM Resin Lead Screw typerm / Resin MoBo MRH Features A -phase Stepping Motor is mounted directly onto the shaft end of a Resin Lead Screw, which is multi-use product. Lead Screw Shaft is ideally constructed to form the Motor Rotor Shaft. Since combining the Motor Shaft and Lead Screw Shaft, Coupling-less, saving total length, and reducing labor cost can be achieved. MRH Nut of polyamide type Resin with good sliding properties is employed. It can be used without Oiling. The Shaft is manufactured from Stainless Steel JIS SUS34, which gives excellent corrosion resistance. Preload type back lash free typeis also available by Double Nuts wit a Spring in between. Recommended Driver for -phase Stepping Motor is available. / Specifications Shaft Nominal Dia.
