Slew Rings / Turntable Bearings / Slew Drives
For Heavy-Duty Applications

The rugged ball-bearing and crossed roller slewing rings from Isotech are characterized by their large diameter and large bores with only a small cross-section. They were designed for axial, radial as well as combined axial and radial loads. New design concepts and improved manufacturing processes for the ball-bearing and crossed roller slewing rings, enable our customer’s designers to implement completely new solution approaches.

Slew Drives

Slew drives are an all-in-one unit comprised of geared slew ring, drive gear, housing, and motor (electric or hydraulic). Designed for axial, radial, and moment loading.

Socare Slew Drives are powered with hour glass (Double Enveloping) worm technology for increased load handling, efficiency and accuracy.

Socare manufactures a wide variety of drive styles, model sizes, performance ranges, sealing options, and mounting characteristics.

Standard model sizes from 75mm to 800mm in diameter.
