EX planetary gearboxes
Planetary gear units that share the load across several planet gears, giving the highest torque density in the smallest envelope. That makes the EX family the choice for slewing, lifting, mining and heavy travel drives where torque is high and space is tight. SES holds the range as an authorised STM Team distributor, covering series EX (inline), EXB (bevel input), EXR, EX-V (slewing); stages Multiple planetary stages, high ratios; torque High output torque class (kNm range); inputs IEC/hydraulic motor, free input, brake adaptor. Executions include EX (inline), EXB (bevel input), EXR, EX-V (slewing). It is specified most often into slewing drives and winches and lifting. 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 EX planetary gearboxes in the parts of a plant where this particular duty actually occurs. In practice that means slewing drives, winches and lifting, mining and mineral processing, and equally heavy travel drives, drum and mixer drives. What links them is the duty rather than the machine name — type: Planetary (epicyclic). 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. Very high torque in a small envelope — EX planetary sized on output torque Right-angle input into the planetary — EXB bevel-input or EXR variant Slewing / rotation drive with pinion — EX-V slewing configuration 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.
Engineered-to-application — capture output torque, ratio, input (electric/hydraulic) and duty cycle; brake and backstop adaptors are specified at build. Send the designation off the failed part and we will confirm the STM Team equivalent and stock position.
