Product Overview
Built to meet the demanding requirements of European-standard motion control, the VRS Right Angle Planetary Gearbox provides low backlash performance (≤3 arcmin), making it ideal for high-precision CNC positioning and closed-loop servo applications. The internal helical gear train enables quiet and vibration-free transmission, significantly reducing noise while improving rotational smoothness.
The gearbox utilizes an integrated ball-bearing support structure that boosts rigidity, increases radial and axial load tolerance, and ensures long-term durability under dynamic shock loads. With a service life exceeding 20,000 operating hours, the VRS Right Angle Planetary Gearbox series delivers exceptional performance with no need for lubrication replacement throughout its operational lifespan.
Whether the application requires high-speed input (up to 10,000 rpm depending on ratio), heavy-duty torque output, or ultra-consistent positioning performance, the VRS Right Angle Planetary Gearbox provides a reliable solution for industrial and automation environments.
The VRS Right Angle Planetary Gearbox series includes multiple frame sizes—VRS060, VRS075, VRS100, VRS140, VRS180, VRS210, VRS240—each available in single-stage and two-stage configurations with a broad range of reduction ratios. The uploaded technical specification sheet provides detailed data such as torque ratings, input speed limits, backlash levels, torsional rigidity, radial/axial load capacity, and rotary inertia.
