UDL/UD Mechanical Speed Variators two

Achieve precise mechanical speed control with Raydafon’s UDL/UD variators—the reliable alternative to electronic drives. These robust units use planetary gearing to deliver stepless speed adjustment from 1:4 to 1:7 ratios, ideal for mixers, conveyors, and rotary tables. Featuring splash-proof construction and overload protection, they thrive in harsh industrial settings. Raydafon’s VariLock™ system prevents speed drift, ensuring consistent output even under varying loads. With minimal maintenance requirements and a 10-year lifespan, UDL/UD variators are the cost-effective choice for simple, durable speed control.
