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 ...

BorgWarner. has filed a patent for a charging device for internal combustion engines or fuel cells. The device includes a compressor with a unique thrust bearing design that allows for fluid flow from ...

We've carefully disassembled this Garrett TP-38 turbo, making sure to clean all the parts before reassembly. Turbocharger journal bearings are made from a soft material, the surfaces are the first to ...

Journal bearing design is complex. It involves optimizing clearances, bearing length, minimum film lubricant, viscosity, flow rate, and inlet slots. Design equations are available, but their solution ...

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 ...

Establishing proper bearing clearance requires serious dedication to the science of reading a micrometer. Checking the crank means measuring each journal in at least four places to check for ...

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 ...
