Turntable Bearings

       Turntable Bearings (Swing Gears, Swing Bearings, Slewing Rings, Slew Rings)Our best-known product, available in several versions and sizes, for the most varied load conditions. A varnished version is also available upon request. It is applied in several industrial fields where there is rotation between parts of machinery and for traditional applications such as for irrigators, agricultural vehicles, airport trailers, snow-makers.

       SANBURG BEARING INT'L LTDturntable bearings are bearings with a large outer diameter and large inner diameter with small cross section, which are built for axial, radial and combined axial, radial and moment loads. Improved manufacturing processes and new construction concepts enable totally new solutions in small, demanding and highly precise applications to the technical designers, for example in the aircraft industry or in mechanical engineering.

       Turntable bearings (sometimes referred to as slewing ring bearings) are 4 point contact thin section type ball bearings.  Preload can be reduced for low torque or increased for high rigidity requirements.  For low turning torque we will assembly each bearing with special low friction PTFE seals.

        Cost Savings  - Bolt holes in the inner and outer rings eliminate the need for precision machined shoulders and bores by mounting directly to flat machined surfaces.  Materials - High quaility bearing steel is used unless otherwise requested.  For corrosion resistance requirements we will offer speical plating or will use stainless steel materials.
