Kaydon slewing rings (turntable bearings) are now available in smaller sizes from R.A. Rodriguez. Thanks to improved manufacturing methods and design concepts, the Kaydon slewing ring bearing range now starts at just 38mm bore diameter and only 6.5mm thick. And these smaller components are suitable for diverse applications, from inclusion in lightweight booms for material handling systems to positioning tables in the precision manufacture of optics and semiconductors.
A benefit of this type of bearing is that it simplifies the design and enables cost-effective and hassle-free assembly. It is an excellent replacement for the traditional 'king post' design. Normally supplied pre-lubricated, Kaydon slewing ring bearings are sealed and can be specified with an integral gear or plain. As standard they come with mounting holes, ready to be bolted directly to the assembly.
Two series of Kaydon slewing bearings are available from R.A. Rodriguez ex-stock. The standard industrial class MTO bearing range with bores ranging from 50mm to 324mm are supplied with through or tapped holes. Their standard clearance and precision makes them most suitable for inclusion in lift booms, assembly tables, rotary transfer lines and other applications requiring simple rotary movement.
Where greater accuracy and a smaller design space are the principal criteria, Kaydon Reali-Slim turntable bearings are recommended. These are now available in sizes from 38mm (1.5 inches) to 152.4mm (6 inches) and are just 6.35mm (0.25 inch) in height. This range has evolved from the popular Kaydon Reali-Slim standard range, is manufactured in 440C stainless steel and is sealed for life.
As with the standard range, the Kaydon Reali-Slim turntable bearings may be specified with a number of options. These include internal or external gear or plain diameters, reduced clearance or preload, and various hole types. Typically these high-quality bearings are used in precision automation systems, inspection tables and radar antennae.
