Many types of bearings are used to reduce friction between two surfaces. Editor's note: An updated version of this information can be found here. Bearings are used to help reduce friction.

The ball bearing can only work if the balls are kept ... and uneven spacing would cause the bearing to be weak under loads from a certain direction. So most bearings use cages to separate and ...

The nut supports a table, arm, or other load that needs to move in a straight line. Re-circulating ball bearings within the nut follow the shaft’s threads and distribute the load from the table ...

To solve repeated bearing failures in high-temperature refinery dampers, engineers replaced traditional steel components with ...

Some vehicles have upper and lower front ball joints, and depending on the suspension design either can be the load-bearing joint that carries the vehicle’s weight (load-bearing joints tend to ...

It works by pressing the edge of three bearings fairly hard up against a ... but it’s not obvious how a thread that gives under excessive load is a plus, unless you’ve crashed your printhead ...

During testing, I became an instant fan of the Leofoto LH-36LR Ball Head. It’s nicely compact and lightweight but a real over-achiever in terms of sturdiness and load-bearing ability.

(Tim Carter) Perspective by Tim Carter Q: I have this load-bearing post right in front of ... might put a toothpick into a juicy watermelon ball or piece of cheese. You don’t want support ...

Such loads could easily destroy the internal stepper motor bearings in a short time, so they opted for some double-sided reinforcement. To alleviate the problem, the introduced two thrust bearings ...
