Shaft-mounted reducers
Shaft-mounted reducers that fit directly onto the driven shaft and take their reaction through a torque arm, removing the coupling, base and alignment of a foot-mounted drive. They are the standard fit on conveyor head shafts, held on with a taper bush or shrink disc. SES holds the range as an authorised STM Team distributor, covering base units PT parallel, O bevel-helical (hollow shaft); fixing Taper bush or shrink disc; reaction Torque arm with rubber buffer; options Backstop, drive cover, motor mount platform. Executions include PT (parallel, taper bush), PT (shrink disc), hollow-shaft o, with backstop. It is specified most often into belt conveyor head shafts and bucket elevators. 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 Shaft-mounted reducers in the parts of a plant where this particular duty actually occurs. In practice that means belt conveyor head shafts, bucket elevators, screw conveyors, and equally aerators, bulk-handling drives. What links them is the duty rather than the machine name — type: Shaft-mounted (parallel / bevel-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. Drive straight onto the driven shaft — Shaft-mounted PT with torque arm Right-angle shaft-mounted layout — Hollow-shaft O bevel-helical Frequent removal expected — Shrink disc over taper bush for easy release 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.
Match the bore to the driven-shaft diameter exactly and fit a backstop on any incline — a shaft-mount with no hold-back will run the load back. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
