A slew drive (or slewing drive) is a compact gearbox system enabling controlled 360° rotation under extreme loads. Combining aworm gear mechanism,slew ring bearing, andintegrated motor, it delivers high torque with pinpoint accuracy – critical for solar trackers, cranes, and excavators.

Key Components:

Slew Bearing:Handles axial/radial loads

Worm Gear:Provides self-locking safety

Housing:Protects against debris & corrosion

Seals:Ensure lubrication retention

Why Engineers Choose Slew Drives:

• ±0.1° positioning repeatability

• 20:1 to 300:1 gear reduction ratios

• IP66-rated weather resistance

• 50,000+ hour service life

Pro Tip: Opt for helical gears when noise reduction is critical; worm gears excel in vertical load scenarios.
