Varvel’s RS/RS Series 2-Stage Worm Gearboxes are engineered to deliver reliable performance in applications requiring very low output speeds and high reduction ratios in a compact form. By combining two worm gear stages, this series effectively enhances torque output while maintaining a small footprint, making it well-suited to installations with limited space. The RS/RS configuration is a dependable choice for general industrial systems where space efficiency, smooth operation, and ease of integration are essential.

Features of The RS/RS Series

This two-stage worm gearbox series offers a straightforward solution for achieving high reduction ratios up to 10,000:1 without the complexity of larger gear systems. Its compact, dual-stage design provides increased torque at reduced speeds, ensuring steady, vibration-free motion even in continuous-duty applications. Housing materials vary by size, with smaller units constructed from lightweight yet durable aluminium, and larger sizes manufactured in cast iron for added strength.

Designed with versatility in mind, the RS/RS Series supports a range of configurations thanks to its modular layout, including flexible motor mounting options and output shafts. The gearboxes are factory-lubricated and sealed for life, helping to reduce downtime and maintenance requirements. Their quiet operation, robust construction, and ability to handle demanding reduction needs make them a solid fit for precision-driven setups across multiple sectors.
