Turntable Bearings

 

           The rugged ball-bearing slewing rings from SANBURG are characterized by their large diameter and large bores with only a small cross-section. They were designed for axial, radial as well as combined axial and radial loads. New design concepts and improved manufacturing processes for the ball-bearing slewing rings, enable our customer's designers to implement completely new solution approaches. The bearings are very easy to assemble and demonstrate their properties particularly in small, sophisticated and high precision applications such as in the aerospace industry or in the special machinery area.

 

            The bore diameter of the SANBURG ball-bearing slewing rings is at least 50millimeters. The bearings are available with and without gear teeth, optionally in a corrosion-resistant or a customer specific tailor-made design. Turntables require axial bearings to rotate freely. In essence, bearings are two plastic or metal circles sized to fit together, one inside the other. One of these bearings is fixed to a solid mass located on one side the unit, while the other side is fixed to a solid mass on the other side. An axial bearing is one where weights are applied parallel to the spin axis.

 

           For example, consider a Lazy Susan turntable found on kitchen tables or in kitchen cabinets. Though loaded with spice jars or other food items the plate spins freely. In addition to prefabricated components, bearings are available as individual pieces. Assembling piecemeal bearings offers more options for sizing and functionality.

 

           A bearing is generally used to allow controlled relative motion between two parts. This will usually be in a linear or rotary movement. Different bearing types will allow for different movements, and so the classifications will be vast. A turntable will provide the framework that will transit the load to the bearings.

 

           Turntable bearings can accommodate axial, radial and moment loads. R.A. Rodriguez Ltd is one of the leading companies providing bearing and precision components to the UK, Scandinavian and Irish market. Derived from USA based R.A. Rodriguez Inc., which was established in 1929, the off-shore business now acts as a representative for leading manufacturers that supply to this field.

 

            Unlike linear bearings which are housed or mounted on a shaft, turntable bearings are mounted directly to a seating surface. There are several different types of turntable bearings. Standard turntable bearings feature a single row of ball bearings, a standard bearing raceway, and four points of contact between the balls and the raceway. Double row turntable bearings will effectively double those figures of standard turntable bearings, and triple row turntable bearings are also available.

 

             R.A. Rodriguez offers lightweight turntable bearings in a range of varying diameters. These can be geared or ungeared, depending on the use of the turntable bearing. R.A. Rodriguez also offers a service where if a customer requires a turntable bearing for a design or configuration not shown, will create a custom bearing design for them. All of the turntable bearings are manufactured in stainless steel, a material known for its lightweight and durable qualities.
