Falk & Rexnord gear drives
Enclosed helical and bevel-helical gear reducers for heavy continuous-duty power transmission in parallel-shaft, right-angle, and shaft-mounted arrangements. Addresses high-torque speed reduction where worm efficiency losses or motorized reducers are inadequate. SES holds the range as an authorised Regal Rexnord distributor, covering gearing Helical and spiral-bevel-helical; ratios Single to triple reduction; efficiency ~97-98% per helical stage; housing Cast iron / rugged fabricated. Executions include falk quadrive (type A/JR), ultramax parallel & right-angle, V-Class (VPD/VHD), Y-Class, among others. It is specified most often into belt conveyors and bucket elevators. Every part is genuine Regal Rexnord 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 Falk & Rexnord gear drives in the parts of a plant where this particular duty actually occurs. In practice that means belt conveyors, bucket elevators, mixers and agitators, and equally crushers, cooling-tower fans, extruders. What links them is the duty rather than the machine name — type: Helical / bevel-helical enclosed. 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 Regal Rexnord range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Shaft-mounted on a conveyor needing hold-back — Falk Quadrive (Type A) with integral backstop Right-angle input needed — Ultramax or V-Class right-angle bevel-helical Efficiency vs worm reducer — Helical drive at ~97-98% per stage vs worm 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.
Confirm mounting position and orientation before stocking; lube fill and vent-plug locations are position-specific and a wrong fill scraps the gearset. Send the designation off the failed part and we will confirm the Regal Rexnord equivalent and stock position.
