■Oldham coupling ・Coupling that transmits power through a spacer in the center ・Especially excellent in correction effect for eccentricity/declination -Simple structure, easy to assemble and maintain ・Because the spacer has a slip structure, even if there is eccentricity, the reaction force is small and the load on the shaft and system is reduced. ・Provide various spacers that can be used in special environments (vacuum or high temperature) ■Structure and materials ・Hub (Material: High strength aluminum alloy/Surface treatment: Anodizing) ・Spacer (Material: Polyacetal) ・Fastening bolt (Material: SCM435/Surface treatment: Black oxide film) *Product numbers SOH-70C, 90C, and 120C (clamps) have electroless nickel plating as the standard specification, so the fastening bolts also have electroless nickel plating. *Product numbers SOH-6,8,10,12 (set screw) and SOHM-12C (clamp) have unprocessed surfaces as standard.
