Renold couplings
Shaft couplings that connect driver to driven machine while absorbing misalignment, shock and torsional vibration, across one of the widest ranges available. Types run from torsionally flexible rubber, jaw, pin-and-bush and tyre couplings through all-metal gear and torsionally-stiff chain couplings to fluid couplings for soft-starting high-inertia loads. SES holds the range as an authorised Renold distributor, covering flexible Rubber-in-shear / tyre for shock and vibration; gear All-metal, high misalignment, AGMA compatible; pin & bush Maintenance-free torsionally flexible; jaw Spider element, shock absorbing. Executions include gearflex (gear), pinflex (pin & bush), spiderflex (jaw), tyreflex (tyre), among others. It is specified most often into electric-motor drivelines and diesel engine and generator sets. 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 Renold couplings in the parts of a plant where this particular duty actually occurs. In practice that means electric-motor drivelines, diesel engine and generator sets, marine propulsion, and equally pumps, fans and compressors, rolling mills and heavy plant, mass transit / rail. What links them is the duty rather than the machine name — function: Connect shafts, absorb misalignment/shock. 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. High-inertia load needing soft start — Fluid coupling (Hydrastart) Large misalignment at high power — Gear coupling (Gearflex) Hot or hostile environment, all-metal needed — Torsionally-stiff chain coupling (Chainflex) 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.
Selected by torque, speed, bore and misalignment, not size alone — capture both shaft diameters and the driven machine before quoting; stock common jaw/tyre elements as wear spares. Send the designation off the failed part and we will confirm the Renold equivalent and stock position.
