Hub City worm reducers
Right-angle worm gear drives with a 30-degree pressure-angle tooth form spanning small to large center distances and very high reduction ratios in single, double, and triple reduction. Addresses high-ratio, high-torque right-angle reduction with strong overhung-load capability. SES holds the range as an authorised Regal Rexnord distributor, covering type Single/double/triple-reduction worm; pressure angle 30 deg tooth form; centre distance 1.33 in to 10 in; ratios 5:1 to 216,000:1. Executions include single-reduction worm, double-reduction worm, triple-reduction worm, helical-worm, among others. It is specified most often into aggregate and bulk conveyors and rotary tables. 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 Hub City worm reducers in the parts of a plant where this particular duty actually occurs. In practice that means aggregate and bulk conveyors, rotary tables, agitators, and equally mixers, augers, packaging machinery. What links them is the duty rather than the machine name — centre distance: 1.33 in to 10 in. 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. Very low output speed needed — Double/triple reduction up to 216,000:1 High overhung or thrust load — Size on OHL/thrust rating, not torque alone Single motorized package — Order as a worm gearmotor (integral C-face motor) 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 the 2-3 center distances used locally rather than the full range; the 30-degree tooth form is not interchangeable with 14.5/20-degree competitor worms. Send the designation off the failed part and we will confirm the Regal Rexnord equivalent and stock position.
