The U40 from SITI is a light-duty worm reducer built on the 40 mm centre-distance worm gear frame and supplied with a standard input shaft for coupling to a separately sourced motor, belt drive or handwheel.
- Suits slow-turn conveyors, coolant pumps and rotary indexing tables
- Compact 40 mm aluminium housing with bronze worm wheel and case-hardened steel worm for quiet, self-lubricated running
- Universal mounting: foot, flange (B5/B14) or combined — output hollow bore to suit your driven shaft
- Self-locking behaviour is fully established at this ratio, making it a popular pick for safety-critical lifting and hold applications
- 15/1 reduction — strong torque gain while keeping output speed practical for most low-speed conveying tasks
- Made in Italy by SITI S.p.A.
