Lightweight Slewing Ring Gear Drive SP-I 0641

What Is SP-I 0641 Slewing Drive?

SP-I 0641 is a compact and lightweight spur gear slewing drive engineered for high-precision rotary motion under dynamic and static load conditions. This model combines a robust slewing bearing with a hardened gear ring and matched pinion set, designed to deliver efficient torque transmission with low backlash and high reliability.

Built to serve a wide range of industries such as construction machinery, aerial work platforms, industrial automation, and energy systems, SP-I 0641 excels in applications where space is limited but performance cannot be compromised. Its IP65-rated enclosure provides excellent protection in outdoor and dusty environments, while the design accommodates either electric or hydraulic motor integration for flexible power input.

With a gear ratio of 12.2 and a torque capacity of up to 6550 N·m, this model provides the perfect balance of power, precision, and durability, making it an ideal solution for medium-duty rotary applications.

Key Features & Advantages

Optimized Gear Design for High Efficiency
The drive features a 15-tooth pinion meshing with a 183-tooth ring gear, delivering a smooth gear ratio of 12.2. This configuration ensures high transmission efficiency while minimizing backlash, making it ideal for precision-controlled rotation.

Compact & Lightweight Structure
SP-I 0641 offers a space-saving solution without sacrificing load performance. Its reduced weight is beneficial for mobile platforms and articulated machinery where low mass and compact size are essential.

IP65-Rated Sealed Housing
The unit’s fully enclosed design ensures long-term durability in outdoor, dusty, or wet environments. It protects internal gears and bearings from contaminants, reducing wear and maintenance frequency.

Flexible Motor Interface
Compatible with electric or hydraulic motors, SP-I 0641 allows for seamless adaptation based on application needs, environmental constraints, and available power systems.

High Torque Output
Supports up to 6550 N·m of peak torque, providing robust rotational capability for lifting, tilting, and positioning tasks in mobile or fixed systems.

Interchangeable with IMO SP-I 0641
Its dimensions and performance metrics are designed for global compatibility, allowing users to directly replace similar models from other manufacturers with minimal design changes.

Typical Applications

Aerial Work Platforms (AWPs)
Supports safe and smooth slewing under varying load conditions, ensuring precise positioning and operational safety.

Mobile Cranes and Construction Machinery
Provides high load-bearing capacity for booms, turntables, and rotating platforms in cranes and drilling rigs.

Industrial Automation & Robotics
Enables accurate and repeatable motion in robotic arms and automated production systems, ensuring consistency in positioning and alignment.

Solar Tracking Systems
Facilitates dual-axis or single-axis tracking with high stability and wind resistance for photovoltaic installations.

Marine and Offshore Equipment
Durable sealed design resists corrosion and contamination in harsh marine environments, making it suitable for deck cranes and winches.

Installation and Maintenance

SP-I 0641 is delivered as a pre-assembled, pre-lubricated unit, calibrated to customer-specific mounting dimensions and motor flange interfaces. Installation is fast and straightforward—simply bolt on, connect the motor shaft, and power up. No internal adjustment or grease filling is required at commissioning.

Routine inspection is minimal due to the drive’s sealed construction and high-quality materials. For long operating life, periodic grease replacement (depending on duty cycle and environment) is recommended after extended service.
