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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
