SP-I Slew Drive

Lightweight Slewing Ring Gear Drive SP-I 0941

SP-I 0941 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 machined and assembled, and can be effectively positioned through the base to ensure product stability. While achieving efficient deceleration function, it simplifies the mechanical structure and reduces the difficulty of installation.

Description

What is SP-I 0941 Slewing Drive?

SP-I 0941 is a high-performance spur gear slewing drive designed for applications requiring heavy load capacity, high rotational precision, and compact construction. This model integrates a finely machined slewing ring with a hardened pinion gear, delivering powerful torque and stable rotation under demanding industrial conditions.

It features a modular design housed in an IP65-rated sealed enclosure, making it ideal for harsh environments such as outdoor, construction, and marine operations. SP-I 0941 offers maximum torque up to 9250 N·m with a gear ratio of 17.2, providing excellent efficiency for both dynamic and static loading applications. With flexible motor options—hydraulic or electric—it is widely adopted in sectors such as automation, aerial platforms, and heavy-duty mobile machinery.

Key Features

  • High Torque Output
    Delivers up to 9250 N·m of maximum torque, ideal for heavy industrial motion control and rotating equipment.

  • Integrated Slewing Bearing Design
    Combines gear and bearing into a single compact unit for simplified installation, reduced footprint, and enhanced mechanical stability.

  • Sealed Protection (IP65 Rated)
    All rotating components are sealed inside a robust enclosure, protecting against dust, moisture, and contaminants—ideal for outdoor and high-dust applications.

  • Precision Spur Gear Engagement
    15-tooth pinion and 258-tooth internal ring gear enable smooth rotation with low backlash and high mechanical efficiency.

  • Versatile Motor Adaptability
    Compatible with electric or hydraulic drive inputs depending on system requirements.

  • Interchangeable with IMO SP-I 0941
    Fully compatible with IMO equivalent models, enabling seamless replacement or integration into existing systems.

Typical Applications
