Motion Control – The Engineering Edge – History of Ceramic Bearings.
March 19th, 2026
Editor Motion Control – LM76 offers innovative solutions to problems!
Motion Control – THE SOUL OF A NEW IDEA In 1976, Warren Hamilton, The General Manager of J.C. Tarbell Associates, an internationally recognized designer of plain (sleeve) bearings was asked by a customer to solve a linear ball bearing failure. At the time, Warren and his team spent most of their efforts on traditional rotary, sleeve bearing design. Applications like a revolutionary sintered, high temperature (700F+), self-lubricating aircraft engine stator vane bushing made from nickel, chromium and cobalt – eventually used in every F404 engine employed on the new F-18 Hornet – America’s new topline fighter. Getting back to the linear ball bearing issue… Warren studied the linear ball bearing failure and set-out to find a solution. Read more »
LM76’s Black Racer Bearings Are the Bearings of Choice for Mattress Manufacturer!
March 12th, 2026
Editor The high speed, short stroke, and the dust & debris of a mattress stitching machine proved too much for linear ball bearings! The contamination and short stroke length did not allow the bearing to circulate and caused premature failure.
E. Longmeadow, MA – — LM76’s solution to problem was to replace the linear ball bearings with the ceramic coated “Black Racer Ceramic Linear Bearings” linear bearings. These linear bearings have a Coefficient of Friction of just .04 (lubricated). LM76 offers 5 of the the 6 Lowest Coefficient-of-Friction bearings and bearing systems available. Follow the links below and contact LM76 for help in selecting the best bearing or bearing system for your application. Read more »
Motion Control – The Engineering Edge – Application – ETX Pillow Blocks!

Editor Motion Control – Application – Radioactive Environment
ETX Pillow/Block Bearings for Radioactive Environments

Motion Control – Application – This was a troublesome application. This system is completely submerged in radioactive water at a nuclear power plant. So no Teflon, no seals, no lubrication – nothing that will degrade in a radioactive environment. The majority of components are stainless steel – except for our ceramic coated/supported shafting and our special, designed for this particular application/never made before, ETX self-lubricating linear blocks.

Linear Motion Control Components – FDA/USDA/3-A Dairy Compliant

Editor Motion Control – FDA/USDA Compliant Bearings

Motion Control – Linear Motion – LM76 FluidLine Linear/Rotary bearings are FDA/USDA & 3A Dairy Complaint. They are also caustic wash down inert. FluidLine bearings one piece construction has benefits over traditional Teflon Composite lined aluminum bearings: if you have a wear situation, Teflon Composite Bearings have a .035″ Teflon Composite Liner. Once you wear through the liner, you are into the aluminum shell. FluidLine bearings will simply wear more and more until they are too sloppy and can replaced at your convenience. They are also less expensive in volume because there are fewer manufacturing operations. We can easily design and produce special ID’s, OD’s, Lengths and features such as flanges.
