Based around precision cut and ground helical gears, SPH Flange (SPH-F) offers quiet and smooth torque transmission with standard backlash of <3 arcmin for single-stage ratios. Reduced backlash, at <1 arcmin, is available for applications requiring increased precision. Able to be used within confined spaces, gearbox also features ISO 9409-compatible output flange that facilitates mounting of various machine elements. Ratings reach up to 450 Nm (nominal) and 675 Nm (acceleration torque).
