FinlandWhat is slew drive?
Slew drive is complete ready-to-install unit of slewing ring for transfer of axial and radial forces as well as tilting in a enclosed steel housing.
Tracking precision
Applications that needs great precision and absolute reliability. Precision starting from only 0.10 degrees.
Limitless slewing range
Endless 360-degree rotation without any restrictions. Smooth movements, no stick or slip effect.
Standard models
From small 177.8 mm (7") all the way to up large 533.4 mm (21") raceway diameters.
Slew drive applications
There are limitless possibilities were slew drives can be used and also improve functionality and usability of existing equipment to whole new level. To give you idea what kind of industries they're used on daily basis, here are some examples of where slew drives are commonly utilized.
Standard hydraulic slew drive models
The standard model's screw and ring gear are made from a proprietary steel materials. Recommended greasing interval depends on the application between 50 - 500 hours. The operating temperature of the slew drive should be between -30 and +60 Celsius. Operating outside of recommended temperature range may damage the components.
Here are currently available standard slew drive models that you can order and make your project even more versatile.
