Frequently Asked Questions (FAQs)

1. What are precision balls?

Precision balls, also referred to as loose ball bearings, are precision ground spheres used as rolling elements in ball bearing assemblies. ... Precision balls are used in a wide variety of applications ranging from ball bearing assemblies and precision valves to free wheel mechanisms and kinematic mounts.

2. How do bearing balls work?

Ball bearings use balls to separate two “races,” or bearing rings, to reduce surface contact and friction across moving planes. The rotation of the balls causes a reduced coefficient of friction when compared with flat surfaces rubbing against each other.

3. How do you attach ball bearing balls?

Remove the cage holding the balls in position. Then slide them together, move the inner ring and the balls will fall out. To insert them you just reverse it, no sweat.
