Rings and Gears

Kinematics offers a range of customized components to meet your exacting needs

Slewing Rings

Slewing Rings are designed for use in gear drive systems or rotary devices that require carrying axial , radial and overturning moment loads.

Right Angle Rotators

Ideal for applications that require high torque in a compact. Uses of these rotators include mobile applications like certain man-lifts, truck cranes, dump trucks, utility equipment, and marine applications.

Slew Rings

Slewing Rings Series Overview And Applications

A standard component in KMI single- and dual-axis slewing drives, slew rings are available for separate purchase. Pricing for custom rings can be quoted on request. Contact KMI Sales for price and availability.

Featuring a compact design, they can be manufactured without teeth, with internal or external teeth, with balls, and/or with rollers.

Applications include construction equipment, wastewater treatment machinery, wind-power generation, drilling equipment, logging industry machines, mining equipment, revolving grabbers and winches, and steering applications.

Slew Ring Features:

Critical components of KMI’s patented hourglass worm technology, KMI slewing rings offer numerous features and advantages.

  • Compact and can be manufactured without gear teeth, or with internal or external teeth
  • Single-row ball-bearing design with outer helical gear
  • Available with balls and / or rollers

Specifications For Slew Rings

Our slew rings are custom-designed for every project to the specifications that each application dictates. Generally extending from 7.7kg to 105kg in weight, KMI slew rings offer performance ranges from 133.2kN to 2360kN of axial load holding with rotational movement of 13,556N-m to 271,164N-m. Other sizes and capabilities can be created for specific needs and mounting varies, depending on equipment and type of project.

Proven Reliability

Tested and evaluated rigorously, KMI’s slewing rings meet the standards established by ISO 9001-, CE-, REACH-, and TUV-certified.

Right Angle Rotators

Right Angle Overview And Applications

For high-torque applications in which slewing drives cannot be used, KMI’s Right Angle gearbox provides a powerful alternative in a compact package.

These highly specialized, often customized components are used in man lifts, truck cranes, dump trucks, utility equipment, marine and vehicle applications.

Right Angle Rotator Features:

Powered with KMI’s patented hourglass worm technology for reliable accuracy, our W series rotators offer numerous features and advantages.

  • W rotator gearbox offers high power and rotational control in a compact package
  • Customizable to customer needs

Specifications For Right Angle Rotators

Base model sizes deliver performance ranges from 1,100N-m to 5,000N-m of output torque. Many input and output flanges, splines and motor inputs are available and can be custom tailored to a customer’s needs. Mounting can be achieved horizontally.

Proven Reliability

KMI’s Right Angle Rotators are tested for consistent reliability and meet the standards established by ISO 9001, CE, REACH, and TUV certifications.
