SP-I Slew Drive
Lightweight Slewing Ring Gear Drive SP-I 0411
SP-I 0411 gear slewing drive is a highly efficient gear reduction transmission device, which is widely used in the automatic slewing of industrial machinery, especially in the occasions that require high precision and high speed. The product consists of two or more spur gears or helical gears with different numbers of teeth. These gears are precisely processed and assembled, and can be effectively positioned through the base to ensure the stability of the product. While realizing the efficient deceleration function, it simplifies the mechanical structure and reduces the difficulty of installation.
Looking for a high-speed, heavy-duty slewing drive that delivers performance, durability, and precision in one integrated system? Meet the SP-I 0411 Lightweight Slewing Ring Gear Drive—an IP65-rated external gear slewing drive designed for mobile machinery, automation platforms, and harsh outdoor conditions.

Description
What Is SP-I 0411 Slewing Drive?
The SP-I 0411 is a compact slewing ring gear drive built with a high-performance slewing bearing at its core. It combines rotation, load support, and reduction in one unit, making it a robust alternative to traditional turntable bearing systems. This model features a pre-set 8.40:1 reduction ratio and supports both hydraulic and electric motor inputs.
Its fully enclosed housing protects critical components from dust, rain, and temperature extremes. Designed for low-speed, high-torque rotary motion, it performs reliably in construction machinery, automated equipment, and heavy-duty transport systems.
Key Features
✔ Core slewing bearing design – Ensures smooth rotation under load and high-speed conditions
✔ IP65-rated sealing – All-weather operation, dustproof and rainproof
✔ Hydraulic or electric motor compatibility – Flexible integration
✔ Factory-filled with Mobil EP2 grease – Plug & play, no commissioning required
✔ Speeds up to 30 RPM – Ideal for continuous or semi-continuous motion
✔ Interchangeable with IMO SP-I 0411 – Direct replacement, globally compatible
✔ Compact & maintenance-friendly – Fewer components, longer service life
Typical Applications
The SP-I 0411 slewing drive is widely used in:
Aerial work platforms
Construction equipment (e.g. cranes, excavators, drills)
Automated assembly or rotation platforms
Mobile robotic arms and track-mounted systems
Off-road vehicles with hydraulic power units
Marine deck equipment and solar trackers
Its all-in-one structure simplifies installation, cuts down system costs, and improves long-term durability.
