Slew Bearing, Rings and Gears

Overview and Applications for KT and KTE Slew Bearings

Engineers designing hoist and crane applications, as examples, depend upon durable components that are high-performing and safe under a variety of loads. KMI’s KT and KTE series of slew bearings were engineered specifically for heavy-duty cycles that require low rotational torque with a range of loads, including moment, radial, and thrust. Built with the quality that KMI is known for, the end user can be confident that these bearings will consistently and reliably support the application throughout its service life.

Features of the KT / KTE Series Slew Bearings:

• Arch raceway design with maximum ball count supports applications requiring low rotational torque
• 4-point contact ball bearings support a range of loads, including moment, radial, and thrust
• Economical, heavy-duty bearings
• Available in non-geared (KT series) and externally geared (KTE series) options
• Mating pinions available
• Range in size from 4 – 47 inches OD (100 – 1,200 mm)
• Stocked in the US for quick shipments

Overview and Applications for KR and KRE Slew Bearings

Applications such as industrial positioners, light-duty lifts, and factory automation depend on lightweight and large diameter bearings to support loads and movements. Those engineering an application look for flexibility in bearing design, how the bearing is physically integrated and mounted, and how it is driven. KMI’s KR and KRE series of bearings provide the engineer with the ability to support radial, axial, and moment loads from a single platform in their designs.

The end user can be confident that the bearings, built with the quality that we’re known for, will provide consistent and reliable support throughout their service life.

Features of the KR / KRE Series Slew Bearings:

• Arch raceway design easily supports applications requiring low rotational torque
• 4-point contact ball bearing
• Economical, lightweight, flanged design for light- and medium-duty applications
• Available in non-geared (KR series) or externally geared (KRE series) options
• Mating pinions are available for the KRE series ranging in size from 20 – 47 inches OD (500 – 1,200 mm OD)
• Stocked in the US for quick shipments

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

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
