Slewing bearings & slew drives

Rotation solutions for machines that cannot stop

Slewing rings, worm-gear slew drives and spur gear drives, machined to your drawing and shipped with the inspection record that proves what is inside the box.

Product families

Four families, one engineering contact

Every project starts with the same three questions: what has to rotate, how much load does it carry, and what turns it. Answer those and the structure, the hardening and the sealing follow.

Slewing Bearings
SXQ series

Seven structures from four-point contact ball to three-row roller, geared or plain.

Slew Drives
SXD series

Sealed worm-gear drives with self-locking output for trackers, cranes and platforms.

Spur Gear Drives
SXG series

Higher torque and output speed where a worm drive is too slow.

Custom & Gear Parts
to drawing

Reverse-engineered rings, matched worm gear pairs and parts to your drawing.

Why buyers stay

The quotation tells you how it is made

Two suppliers quote the same drawing and deliver different rings, because hardening depth, grinding allowance and clearance setting never appear on the drawing. Our offers state them, so you can compare on equal terms.

Applications we size every week

Solar Trackers

Single and dual axis drives sized on wind back-torque, not just module weight.

Construction Machinery

Excavator swing circles, crane rings and platform turntables.

Port, Mining & Marine

Three-row roller rings for continuous duty under heavy axial load.

01

Send the duty

Drawing, load case, motion or just the machine model.

02

Technical proposal

Structure, ratio, hardening and sealing — with reasoning.

03

Approved drawing

Nothing is machined until you sign off the drawing.

04

Inspection record

Hardness, clearance, torque and backlash, per batch.
