Decode the SEW model string
We separate gearbox family, mounting form, size, ratio, motor frame, and accessory codes before discussing price.
Drawing-led interchange review for SEW R, K, F, and heavy-duty gearmotor families used in conveyors, packaging lines, AGV modules, and automation equipment.
For buyers comparing SEW lead time, service price, or regional availability against a China-sourced replacement path.
| Family | Common Examples | Equivalent Path | Review Notes |
|---|---|---|---|
| R Series Helical Gear Units | R37, R57, R77, R97 gearmotor envelopes | HR-Series helical gearbox review | Check foot pattern, output shaft length, motor adapter, service factor, and lubrication position. |
| K Series Helical-Bevel Gear Units | KA/KAF/KAZ hollow shaft and flange-mounted variants | HK-Series right-angle replacement | Confirm hollow shaft diameter, torque arm geometry, flange pilot, and terminal-box clearance. |
| F/S Series Automation Gearboxes | Parallel shaft and worm gearmotor assemblies | Application-specific automation gearbox selection | Review ratio, duty cycle, heat rise, mounting angle, and washdown or dust exposure. |
Replacement projects are screened in a fixed order so the quote does not hide mechanical, thermal, or validation risk.
We separate gearbox family, mounting form, size, ratio, motor frame, and accessory codes before discussing price.
Footprint, shaft, pilot, and adapter geometry are checked first so a torque-equivalent unit does not become an installation mismatch.
Continuous conveyors, packaging cycles, and high-inertia loads are reviewed against real duty, not only catalog nominal torque.
No. Some families can be matched closely, while others need an adapter plate, shaft change, or motor-interface review. We flag this before sample order.
We can start from the model number, but final quote accuracy requires nameplate, mounting position, and interface dimensions.
