Custom gearboxes
Engineered-to-order gear units for applications where no standard frame fits — special ratios, mounting, materials, shaft arrangements or duty. STM builds from its High Tech, Industrial and planetary platforms and provides full 2D/3D CAD configuration for integration. SES holds the range as an authorised STM Team distributor, covering platforms High Tech, Industrial RX, EX planetary, worm; custom Ratio, mounting, shafts, materials, sealing; engineering CAD configuration via CADENAS; drawings on request; interfaces PAM inputs, QL bushings, base plates. Executions include special ratio / mounting, reverse-engineered replacement, special materials / coatings, integrated drive packages. It is specified most often into OEM machine integration and retrofit / obsolete-unit replacement. Every part is genuine STM Team 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 Custom gearboxes in the parts of a plant where this particular duty actually occurs. In practice that means OEM machine integration, retrofit / obsolete-unit replacement, special-duty industrial drives, and equally non-standard mounting or ratio, extreme-environment drives. What links them is the duty rather than the machine name — scope: Bespoke / non-standard units. 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 STM Team range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. No catalogue frame fits the machine — Custom unit from the nearest STM platform Replacing an obsolete gearbox — Reverse-engineered to the existing footprint Special material / environment — Bespoke materials, coatings and sealing 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.
Send the drawing, the failed unit or the machine constraint — the more of the duty (torque, ratio, mounting, environment) captured up front, the faster the quote. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
