Wire race bearing design
(OP)
Hi,
Can anybody help me with the design calculations of wire race bearings. It is a four point contact bearing. I have the loading conditions and the overall dimensions for the bearing.
Thanks

What is your application? The same technology should apply
as other bearings. You have to find out the conformity
radii of the races and also the pocket dimensions. Often they
are the same width and height making the contact angles 45 degrees. Many of them are stainless steel and you have to know the hardness etc of the wires and balls or rollers. I assume you
are talking about ball bearings. I had seen some early papers from Russia but not certain if that is where the technology developed or not. Rotek and Kaydon make them for military applications as well as for some space designs.

It is for a medical equipment weighs around 680 kgs and yes the wires are at 45 degrees . I have the dimensions for wires and balls used. while investigating I came to know that the wires and balls were bought from different suppliers and then assembled on site in the company. So if we want to continue the same supplier for new project I need to design the bearing frm start and validate that it is safe to use.
So I was wondering if any one can help me with design calcualtions of such bearings?
RE: Wire race bearing design
by yourself. If the wires and balls were installed as you say in house, were they installed by the suppliers? Often a series of shims are used to control the clearance or preload within the system. Because of manufacturing tolerances, the shims are often
varied to achieve the proper clearance or preload.
