Torque limiters
Mechanical torque limiters that protect a drivetrain by slipping or disengaging when torque exceeds a set point, saving the gearbox, chain and driven machine from a jam or shock overload. STM offers them as an accessory into its worm and reducer ranges as well as standalone. SES holds the range as an authorised STM Team distributor, covering types Friction-slip and ball/roller-detent; trip torque Adjustable via spring pre-load; mount On input or output; into worm reducers; reset Automatic (friction) or manual (detent). Executions include friction-plate limiter, ball-detent limiter, reducer-integrated accessory, with trip switch. It is specified most often into conveyors and indexing drives and packaging machinery. Every part is genuine STM Team through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Torque limiters in the parts of a plant where this particular duty actually occurs. In practice that means conveyors and indexing drives, packaging machinery, mixers and augers, and equally machine-tool drives, any jam-prone driven load. What links them is the duty rather than the machine name — function: Overload / jam protection. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the STM Team range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Continuous slip acceptable on overload — Friction-plate torque limiter Positive disengage-and-signal on trip — Ball-detent limiter with proximity switch Integrate into the reducer — STM worm/reducer torque-limiter accessory Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Set the trip torque above running peak but below the weakest driveline component — a limiter set too high protects nothing. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
