In a sense, thrust bearings are 90° angular-contact bearings. In a sense, thrust bearings are 90° angular-contact bearings. They support pure thrust loads at moderate speeds, but for practical ...

These days, it’s common among us hackers to load a stepper motor with forces in-line with their shaft–especially when we couple them to leadscrews or worm gears. Unfortunately, steppers aren’t really ...

That is, thrust bearings where both end ‘washers’ are groved to form a ball-race, and: one washer is sized to clear the 8mm shaft and fit the 16mm bore, while the other is sized to fit the 8mm shaft ...

Editor's note: An updated version of this information can be found here. Bearings are used to help reduce friction. Metal-upon-metal contact produces large amounts of friction. The friction adds to ...

Garrett's dual ball-bearing turbos were originally designed for diesel engines. Diesels were known to produce throttle tip-in smoking. The smoke was the byproduct of a rich condition that occurs after ...

A study of 10 current production passenger car automatic transmissions with respect to environment, bushing and washer material, journal and thrust runner materials and finishes, loads and speeds, and ...
