The U40 from SITI is a light-duty 100:1 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.
- Ideal for very slow drives, winding equipment and rotating sculptures/displays
- 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
- Output around 14 rpm from a 4-pole motor; strongly self-locking
- 100/1 reduction — the deepest ratio available in the U40 frame, giving a 100× torque multiplication
- Made in Italy by SITI S.p.A.
