Sprocket Friction Torque Limiters

The table lists 10 sizes with trip torque from 2.9 to 1080 N·m, bores up to Ø90 mm, maximum speed 1200 rpm. The slip torque is set on the machine within each size's range; other bores and combined sprocket / pulley / coupling versions are made to drawing.

CTL sprocket friction safety couplings (torque-limiting) slip on overload while providing shaft-to-shaft drive; combine with steel disc couplings, tolerate temperatures up to 280 ℃, and use spacers of different lengths to suit shaft spacing. Torque range 2.9–1080 N·m. Choose the CTL where a chain drive needs overload protection built into the sprocket itself: on overload the friction plates slip while the shaft keeps its drive, protecting the chain, gearbox and motor — typical on conveyors, packaging lines and machine tools. It tolerates up to 280 °C and comes with spacers of different lengths to suit shaft ends.

Yes. Everything on this page is made to drawing, and the table is only the standard-size subset of the catalogue. Minimum order quantity is one piece — we routinely make single replacement parts for OEMs whose original supplier has discontinued the item. Send a DWG, STEP or PDF drawing (or a sample part): you get a formal quotation within 24 hours after the information is complete, and the first article ships within 30 days of drawing approval, with inspection records.

Send: the torque at which the drive should slip (or motor power and speed so we can calculate it), bore diameters and keyways, speed, duty (how often overloads occur), space available, operating temperature, and whether you want a sprocket, pulley, gear or coupling built onto the limiter. We will confirm size and pre-set the trip torque before shipping.
