VRB-090-010-K5-19FB19 low-backlash servo gearboxes

The VRB series from Nidec-Shimpo is a family of high-precision planetary gearboxes for servo motors. According to the model code, this unit has a 90 mm frame size (090) and a single-stage 10:1 ratio (010), with a K5 backlash grade and a motor input adaptation designated 19FB19, indicating a 19 mm input bore and flange arrangement. Backlash for the standard grade is a few arcminutes, and the gearbox has helical gearing for low noise and high torque density, with output flange and a keyed or smooth shaft. The housing is steel or aluminium with permanent grease lubrication and the unit is suitable for continuous servo duty at high input speeds. Efficiency is high, typically about 95 percent for a single stage. Typical applications include robotics, semiconductor equipment, packaging machines, machine tools, and automated assembly stations where precision and compactness are required.
