Gearboxes
Renold Gears designs and builds worm, helical and bevel-helical gear units, from off-the-shelf standard series to custom gearboxes engineered to the application. The range covers in-line and right-angle reducers, shaft-mounted and geared-motor units and heavy-duty drives, backed by a refurbishment service for gearboxes of all makes. SES holds the range as an authorised Renold distributor, covering r / k series In-line helical / bevel-helical units; s / f series Helical worm / shaft-mounted units; jpm worm To 520 Nm, ratios 5:1–70:1; pm geared motor Up to 84 kW. Executions include r series (inline helical), k series (bevel-helical), s series (helical worm), f series (shaft-mounted), among others. It is specified most often into conveyors and bulk handling and water and wastewater (scrapers, clarifiers). Every part is genuine Renold 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 Gearboxes in the parts of a plant where this particular duty actually occurs. In practice that means conveyors and bulk handling, water and wastewater (scrapers, clarifiers), mixers and agitators, and equally rolling mills, escalators, general process machinery. What links them is the duty rather than the machine name — gear types: Worm, helical, 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 Renold range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Compact right-angle reduction, moderate load — S Series helical worm or JPM worm unit High-efficiency in-line or right-angle drive — R Series helical / K Series bevel-helical Heavy-duty high-torque drive — H/HB Series up to 480 kNm 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.
Mostly engineered-to-order — quote by ratio, output torque, mounting and motor frame; offer the refurbishment service as an aftersales option on existing units. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
