Falk gear couplings
Double-engagement gear coupling that transmits high torque while accommodating angular, parallel, and axial shaft misalignment through crowned external hub teeth meshing with internal sleeve teeth. Addresses the high-torque duty where disc couplings run out of capacity and grid couplings run out of size. SES holds the range as an authorised Regal Rexnord distributor, covering type Double engagement (G20), single (G52), vertical (GV20); torque To 14,490,000 lb-in std; 72,450,000 lb-in large Type G; bore/shaft To 21 in (to 56.5 in large Type G); sizes 1010G through 1160/2160G, 21 sizes. Executions include G20 double engagement, G52 single engagement, GV20 vertical, G62/G63/G66 brakewheel & disc-brake, among others. It is specified most often into fans and blowers and overhead cranes. 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 gear couplings in the parts of a plant where this particular duty actually occurs. In practice that means fans and blowers, overhead cranes, belt conveyors, and equally steel-mill roll tables, paper machine drives, sleeve-bearing motors/generators. What links them is the duty rather than the machine name — torque: To 14.5M lb-in (G20); 72M lb-in large Type G. 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. Lube-free / no maintenance access wanted — Switch to a Kop-Flex disc coupling Sleeve-bearing motor or generator — Order limited-end-float (LEF) arrangement Vertical shaft over 10 deg incline — Specify GV20 with sleeve-centering assembly 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.
Stock matched-bore hubs and a grease-fill kit on the shelf; most field failures are relube neglect, not tooth wear. Sleeves and hubs sell separately. Send the designation off the failed part and we will confirm the Regal Rexnord equivalent and stock position.
