Slewing Ring Bearings

Engineering & Manufacturing

Slewing bearings in standard and custom configurations up to 120″ O.D.

Scheerer’s slewing ring bearings are machined and manufactured from the highest quality materials. They are engineered to withstand maximum allowable static and dynamic axial, radial, and moment loads while providing the optimum combination of weight, performance, size, and sustainability.

Slewing Ring and Industrial Turntable Bearings

Slewing ring and industrial turntable bearings are designed for 360 degree rotation under radial, axial and moment loads. Often face-mounted using bolt hole patterns, these unique bearings can support rotation from external components, or can be used as the primary drive feature through an outer or inner ring gear. These bearings come in a wide variety of sizes and configurations, from a 5” ID all the way up through a 150”+ OD, and can provide the perfect bearing solution in many different

applications. Scheerer’s ability to customize these slewing ring bearings is unique, in that they can be used to fill multiple rolls and serve several functions. In addition to offering interchanges for all of the standard series slewing ring in the industry, Scheerer bearing routinely works directly with OEM manufacturers to design application specific units, and can even provide replacements for discontinued legacy slewing ring bearings.’

Slewing Drive Units – Strength and Precision

Slewing drives come in a variety of formats but are primarily based on worm gear mechanisms. Worm gears offer precision and smooth rotation under substantial loads. The combination of a slewing drive / bearing combination reduces the speed but multiplies its torque, making them ideal for applications that require both critical load-holding strength and rotational torque all while providing high-precision movement.
