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. Pacific Bearing, Product Code 4235.
A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
