Geared Motors & Reducers
Helical, worm and shaft-mounted reducers with matched motors, converting motor speed into the torque and output speed the machine actually needs, in the mounting position the layout allows. SES holds the range as an authorised JK Fenner distributor, covering types Helical inline, helical-bevel, helical-worm, shaft-mounted; ratios Approximately 3:1 to 6000:1 in combination units; mounting Foot, B5/B14 flange, shaft-mounted with torque arm; output shaft Solid, hollow, hollow with shrink disc. Executions include helical inline geared motors, helical-bevel right angle units, helical-worm gear units, shaft-mounted reducers, among others. It is specified most often into belt conveyor drive heads and bucket elevator drives. Every part is genuine JK Fenner 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 Geared Motors & Reducers in the parts of a plant where this particular duty actually occurs. In practice that means belt conveyor drive heads, bucket elevator drives, agitator and mixer drives, and equally screw conveyor and feeder drives, tea and rice processing line drives, cooling tower fan drives. What links them is the duty rather than the machine name — types: Helical inline, helical-bevel, worm, shaft-mount. 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 JK Fenner range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Conveyor drive with a shaft-mounted layout — Shaft-mount reducer with torque arm — no coupling, no alignment, quicker to change out. Frequent starts, stops or reversals — A higher service factor than the nameplate suggests; duty cycle, not power, sizes the gearbox. Right-angle layout with high efficiency needed — Helical-bevel rather than worm. Worm units are compact and cheap but lose significant power as heat. 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.
State the mounting position with the order. Oil quantity and fill points change with orientation, and a unit filled for foot mounting will starve the upper bearings if it is installed on a flange. Send the designation off the failed part and we will confirm the JK Fenner equivalent and stock position.
