Parallel-shaft reducers
Parallel-shaft helical reducers where output runs parallel to input, available foot-mounted or shaft-mounted onto the driven shaft. They pack a long reduction into a flat envelope, which suits conveyor and handling drives where axial length is tight. SES holds the range as an authorised STM Team distributor, covering series P, PE, PL (long centre), PT (shaft-mounted); stages Double / triple reduction; output Solid or hollow shaft; shrink disc / QL bush; inputs PAM/IEC & NEMA or free input shaft. Executions include p, PE, PL (long centre distance), PT (shaft-mounted). It is specified most often into belt and chain conveyors and bulk-handling drives. 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 Parallel-shaft reducers in the parts of a plant where this particular duty actually occurs. In practice that means belt and chain conveyors, bulk-handling drives, agitators, and equally aerators, general process lines. What links them is the duty rather than the machine name — type: Parallel-shaft helical. 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. Long centre distance / flat envelope — PL long-centre-distance parallel unit Mount directly on the driven shaft — PT shaft-mounted with torque arm and shrink disc In-line layout preferred — Coaxial A series instead 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.
For shaft-mounted PT, capture the driven-shaft diameter and torque-arm anchor point before quoting — the reaction has to land somewhere solid. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
