S Open Hourglass Slewing Drives

    S Open Hourglass - Applications
    Applications

    The S open hourglass is excellent for low-cost manufacturing equipment that requires daily maintenance and checks or doesn’t need to be covered. Typical uses for this S open-housing slewing drive include many mobile applications such as man-lifts, utility equipment, turntable applications, digger derricks, and steering applications.

    S Open Hourglass - Specifications
    Specifications

    Our base models deliver performance ranges from 3kNm to 220kNm of holding torque, 200Nm to 63kNm of output torque, 500Nm to 271kNm of tilting torque, and gearbox reduction ratios of 30:1 up to 156,600:1. The mounting can be done horizontally or vertically. The drives are available with one of two worm shafts for increased torque. Get all specifications.

    S Open Hourglass - Reliability
    Reliability

    Kinematics S open slewing drives are tested for reliability and consistency. With a guaranteed 30-year field life, these slewing drives can power heavy machines with controlled stability and safety. Our drives have ISO 9001, CE, REACH, and TUV certifications and all aspects of our engineering control are based on creating reliable solutions that meet these standards.

    S Open Hourglass - Performance
    Performance

    Kinematics slew drives are driven by patented hourglass worm technology for ultimate performance. The hourglass worm provides greater stability and precision for better accuracy and efficiency. Kinematics drives engage 5 to 11 teeth of the ring gear at a time, which gives the gear greater strength than standard worms, which only engage one tooth at a time. See how the hourglass worm works.
