Spur‑Gear Slew Drive With Dual‑Axis & Encoder For Precision Rotary Equipment

9 Sep 08, 2026

LDB dual‑axis spur‑gear slew drive is a high‑precision integrated rotary solution based on spur‑gear meshing structure. Equipped with dual‑shaft output and matching precision encoder, this slew drive can provide real‑time angle position feedback while delivering high‑torque output. It solves the positioning deviation problem of ordinary slew drives and meets strict precision‑control requirements for automation and special‑industry equipment.

Different from single‑output slew drives, our dual‑axis spur‑gear slew drive adopts bilateral symmetrical output shaft design. High‑resolution encoder is installed on the output end to collect real‑time rotation angle, speed and position data, and feed back signals to servo control system. Combined with high‑efficiency spur‑gear transmission(92‑96% efficiency), it realizes closed‑loop precise rotation control.

Main Advantages

‑ Dual‑axis synchronous output: Two‑side shaft output, realizing synchronous rotation for double‑end driven equipment.

‑ High‑precision encoder feedback: Real‑time angle monitoring, effectively reduce positioning error, support closed‑loop servo control.

‑ High transmission efficiency: Spur‑gear rolling‑contact meshing, low heat generation, suitable for long‑time continuous cyclic operation.

‑ Adjustable low backlash: Hardened gear pair, controllable backlash for high‑repeat‑position‑accuracy scenarios.

‑ Strong load‑bearing capacity: Integral heavy‑duty housing, withstand large tilting moment, axial and radial loads.

‑ Diversified matching: Match servo motor, stepper motor or hydraulic motor; Encoder model can be customized according to customer accuracy requirement.

Typical Application

Dual‑axis spur‑gear slew drive with encoder is widely used for equipment requiring dual‑end driving and precise angle positioning:

Radar & antenna azimuth‑pitch rotary platform
Heavy‑duty automated welding positioner
Dual‑side driving industrial turntable
Special test equipment and simulation rotary mechanism
Automation palletizing and precise positioning machinery

Custom Support

We support custom parameters including output torque, rotation speed, encoder resolution, installation dimension, protection grade and shaft size. Customers can provide working‑condition data or technical drawings for customized solution evaluation. Every unit will complete strict load test, backlash detection and encoder signal inspection before delivery.

Custom Slew Drives: A Complete Guide to Engineered Rotary Motion Solutions

A Custom Slew Drive is a compact, highly integrated mechanical system that provides precise, high-torque rotational movement. It is an all-in-one unit that combines a slewing bearing (a large-diameter rolling-element bearing) with a worm gear mechanism, a sealing system, and often a built-in motor and hydraulic or electric brakes.
