Introduction of a new bearing liner material--FrelonGold(reg)--in Pacific Bearing's Simplicity(TM) line of bearings has resulted in twice the load rating and more than 2.5 times the life of original Frelon-lined bearings. This results in 20 times the load rating and 270 times the average life as compared to standard linear ball bearings, the company claims. FrelonGold cuts friction from Frelon's average of 0.30 to 0.125, reduces the wear rate from 0.0005 to 0.0001 per 25 million inches of travel, doubles maximum load pressure to 3000 psi, and increases speed capability from 140 sfm to 300 sfm. Like all Simplicity plain bearings, FrelonGold-lined bearings are self lubricating, self cleaning, and can accommodate any combination of linear and rotary motions.

More and more robots are becoming more autonomous all the time. Now Lockheed Martin has completed a demo mission with two completely autonomous robotic vehicles performing resupply, reconnaissance, surveillance, and target acquisition.
Producing high-quality end-production metal parts with additive manufacturing for applications like aerospace and medical requires very tightly controlled processes and materials. New standards and guidelines for machines and processes, materials, and printed parts are underway from bodies such as ASTM International.
