Minuteman Self Lube Linear Bearings™ Are: All Weather/All Theatre Compatible!
March 26th, 2026
Editor Linear Motion – Why are LM76 Minuteman Linear Bearings™ the 1st choice when failure under poor environmental conditions is simply, “NOT AN OPTION?” Because Minuteman Self Lube Linear Bearings™ are exceptionally tough and All Weather/All Theatre Compatible! Unlike linear ball bearings which employ re-circulating balls, LM76 Minuteman Self Lubricating Linear Bearings™ offer a tough ceramic coated shell featuring LM76’s industry leading Minuteman Green Self Lubricating Liner™.
Since there are no balls or mechanical mechanisms in the Minuteman Linear Bearing™, there is no mechanical failure mode. Dirt, dust and debris get wiped away whereas with a linear ball bearing, they get trapped under the seal, filling the ball raceways and freezing the balls – destroying the bearing and grooving the shaft. Minuteman Self Lube Linear Bearing™ can take a pounding from recoil, shock/vibration, vicious environments and high heat.
For this reason the US Navy and the US Army have installed LM76 Minuteman Linear Bearings™ in gun mounts on ships and vehicles.
US Navy – The Navy’s MK95 Mod 2 Machine Gun Mount is for mounting two .50 Caliber M2HB Modified Machine Guns (resulting in a weapon system firing rate of about1,000 rounds per minute). Each weapon is “soft-mounted” and installed with a shock absorber system using LM76 Minuteman Linear Bearings™ to reduce transmitted weapon recoil and to increase gunner controlability and hit probability.
US Army – Here you can see sand/dust build-up on the weapon, mount and tripod. These mounts provide platform stabilization, improve accuracy, and increase hit probability while decreasing the time and effort to install and interchange weapons.
Recent testing at SAIC Surface Platform Integration
Small Arms led to this comment:
” We feel that your (LM76) products will improve our mounts in regard to performance, life and cost.”
Below – Here you can see sand/dust build-up on the weapon, mount and tripod. These mounts provide platform stabilization, improve accuracy, and increase hit probability while decreasing the time and effort to install and interchange weapons.

” You need a linear bearing that can stand-up to sand, heat, shock and overall abuse. This environment (desert) plays havoc with all our systems. Your bearings meet or exceed mission requirements.” Andral, Bob US Army – Iraq Vet
The LM76 Minuteman Linear Bearings™ at the heart of this application.

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.
