The PLE, PLF and PLPE planetary gearboxes are precision right-angle-free inline reducers designed for servo and motion-control applications. With single-stage ratios from 3:1 to 10:1 and backlash held to 8 arcminutes or less, they give machine tools, robotic axes, packaging indexers and automated positioning stages the repeatability that a standard industrial gearbox cannot provide.
A sun gear driving several planet gears on a common carrier shares torque across multiple tooth contacts, so the unit delivers high torque density and high torsional stiffness in a short, lightweight housing. Hardened and ground gearing keeps noise low and maintains accuracy over a long service life, while lifetime lubrication removes the need for routine oil changes on most frames.
We match the gearbox to the motor rather than selling a frame size in isolation: motor shaft diameter, pilot diameter, bolt circle and flange pattern are confirmed against your servo or stepper before the order is released, and the adaptor is supplied fitted. Ratio, backlash class, output shaft or flange form and mounting orientation are all selectable. Where an axis needs lower backlash or a higher ratio, we can propose a two-stage build and state the resulting accuracy.
Each unit is inspected for backlash and run-tested before packing. We can ship the gearbox together with the motor, coupling and cable as a single assembly, consolidating several motion axes into one order. Lead time is confirmed against the configuration at quotation.
Send us your motor model or flange drawing, required ratio, output torque, duty cycle and allowable backlash. We will confirm a compatible frame, the motor adaptor and the expected accuracy, then return a complete selection with a quotation.
