The RC, PM and SS series are general-purpose industrial gear reducers for duty points where a standard catalogue unit is enough: belt conveyors, screw conveyors, mixers, agitators, rotary valves, thickener drives and general machinery of the kind found in cement, aggregate, chemical and water treatment plants.
RC is a helical unit built on a cast iron housing with case-hardened, ground gears; PM is a compact two-stage helical unit for medium ratios; SS is a shaft-mounted unit that needs no baseplate and is tensioned with a torque arm — the fastest of the three to fit on an existing conveyor head shaft.
All three share the same selection logic: we need the driven load, the required output speed, the duty hours per day and the mounting position. From that we confirm the service factor, the size and the motor power, and we send a dimension drawing before the order is released. Units are assembled and run-tested in our works, not shipped loose from stock bins.
- RC helical, PM two-stage helical, SS shaft-mounted — one supplier for the whole plant
- 0.12 to 200 kW, ratios 3:1 to 300:1, output torque up to 20,000 N·m
- Cast iron housing, oil bath lubrication, no special oil required
- Foot, flange or shaft mounting; motor supplied as a matched assembly
- Options: brake motor, backstop, cooling fan, encoder, anti-condensation heater
Standard sizes ship in 25–35 days; special ratios, non-standard voltages and shaft-mounted units with customer-specific bore are quoted with a confirmed lead time. Send the duty point and we will return a selection with a dimension drawing within three working days.
