Understanding Anti-Friction Bearings

What are the two surfaces in anti-friction bearings separated by?

a. Seals

b. Lubricants

c. Races

d. Housings

Final answer:

The two surfaces in anti-friction bearings separated by balls or rollers are known as races.

Explanation:

In anti-friction bearings, the two surfaces that are separated by rollers or balls are called races. The races, typically made of hardened steel, provide tracks for the balls or rollers to roll along, minimizing friction and enabling smooth movement. These bearings are commonly used in machines, motors, and many other types of mechanical systems where reducing friction and ensuring efficient rotation is crucial.
