Projects & News
LM76 grew in 2018 by 10%! We added 3 new machining centers and welcomed 4 new employees.
Project 1 Hell Fire
LM76 has been the chosen supplier
for a linear system on the new Bowhead - Sea Based - Hell Fire Missle Launching System. The design engineering was accomplished between LM76's lead engineer Mike Quinn and engineers at U.S. Naval Engineering, Dahlgren, Virgina. Sea trials have been ongoing
for the past 2 years and a contract has been awarded to Grumman Northrop and Teledyne Brown.
Project 4 NASA
This application required extremely low friction, low and high temperatures and near total inertness. This all 440C linear bearing has a thin dense chrome shell and retainer and is without seals. The stainless balls were removed and replaced with ceramic (silicon nitride) balls to ensure no possibility of cross corrosion between balls and associated components. When this bearing is activated, it must move freely regardless of how long it has remained stationary.
Project 2 Nestles
Nestles Corporate Engineering chose LM76 to design an FDA/Caustic Washdown linear bearing and shaft system for frozen dinner packaging lines. The new design features LM76 NP Coated Pillow Block Housings with a corrosion resistant linear ball bearing that employs LM76's proprietary ETX Scraper Seal end caps. System shafting is our 440C case hardened stainless shafting with ARMX coating for additional hardness and corrosion resistance.
This system manufactures paper towel logs and then slices them into desired lengths. As the robotic arm swings through the logs to slice them to size, the 13 foot log is indexed forward. Under the index tables are pillow block bearings and shafting which allow the the indexing forward. As the blade passes through the bottom potion of the index table, the blade passes through a series of sharpeners which throw off tiny (hard) metal particles which contaminate the bearings -leading to premature bearing failure.
LM76 engineers designed a scraper seal cartridge that has tripled bearing life.
Project 5 Paper System
Project 3 Sargento
Sargento had an application which required FDA/Caustic Washdown compliance. This system required low friction operation and had to able to allow flushing/evacuation of debris from the bearing rail area. LM76's WD2 Water Dog linear block and 300 series stainless rail were chosen and are now installed in several production plants.
