Pegasus Series 1 Experiment    Project: LMN2TY     4.10.19

We were asked by the US Military to design a linear ball bearing that would be corrosion resistant (salt water, mist and air) and survive momentary elevated temperatures. The one overriding design detail was this: it may not actuate for months, a year or multiple years...but when it needs to actuate it must move unimpeded. Typical all stainless linear ball bearings must be lubricated and because 440C requires carbon during hardening, it will oxidize. Even a small amount of cross corrosion between balls and retainers will effect actuation. LM76 engineers decided to disassemble the bearings, apply a TDC (thin Dense Chrome) to the shell and the retainer and replace the steel balls with SiNi (Silicon Nitride) ceramic balls. We believe this technology offers legitimate advantages when FDA compliance, the low frictional characteristics of a ball are essential, lubrication is out of the question and corrosion resistance is an absolute. If you have an application where you have run into a brick wall because of caustics and the inability to lubricate, welcome to Pegasus Series 1 Bearings.
