oil rotators

(AVS / THUMM)

Oil Drive rotators, also known as hydraulic gerotor or G-Rotor rotators, use direct hydraulic pressure acting on an internal rotor system to deliver continuous 360° rotation. Leading manufacturers such as AVS (Austria) and Thumm (Germany) specialise in this robust technology, designed for the demanding conditions of excavators, loading cranes, forestry machines, and material handlers.

Hydraulic oil drives a gerotor (G-Rotor) mechanism — a positive-displacement system with external and internal gearing. Pressure chambers fill and empty alternately, producing smooth, powerful torque. High-quality units feature forged drive shafts, tapered roller bearings, and advanced sealing systems that handle high axial, radial, and bending loads.

  • Faster rotation speeds compared with worm-drive systems — ideal for high-cycle sorting and continuous spinning
  • Smooth start-up and controlled braking
  • Excellent load capacity and compact design
  • High hydraulic efficiency and strong torque output
  • Standardised mounting patterns for easy replacement
  • Proven durability in harsh environments (scrap, demolition, forestry, construction)

Sorting grabs, continuous material handling, chipper feeding, forestry work, and any job where speed and dynamic rotation matter most.

Oil Drive rotators deliver responsive performance and long service life when the priority is efficient, continuous rotation under load.

Worm Drive Rotators

(CAMM GROUP / IMO)

Worm drive (slew drive) rotators combine a precision slewing bearing with a worm gear mechanism. Brands such as Camm Group and Imo produce complete, ready-to-install units that deliver high torque, precise control, and excellent load-holding capability for excavators, cranes, tilt rotators, and specialised attachments.

A hydraulic (or electric) motor turns a worm that meshes with the toothed race of the slewing bearing. The high reduction ratio multiplies torque while the slewing bearing absorbs heavy axial, radial, and moment loads. Many designs offer inherent self-locking characteristics.

  • Strong self-locking / holding ability — the load stays in position even without continuous hydraulic pressure
  • High torque from compact motors thanks to gear reduction
  • Smooth, precise, and controlled rotation
  • Excellent capacity for overhung and moment loads
  • Enclosed, robust construction suited to dirty and outdoor environments
  • Modular, ready-to-install design that simplifies machine integration

Precise positioning work, tilt rotators, holding loads at an angle (posts, beams, branches), boom rotation, and any task where safety and accurate angular control are critical.

Worm drive rotators excel when operators need reliable load holding, fine control, and long-term durability under heavy moment loads.
