Bearing balls are special highly spherical and smooth balls most commonly used in ball bearings but also used as components in things like freewheel mechanisms. The balls come in many different grades.These grades are defined by bodies such as the American Bearing Manufacturers Association (ABMA) a body which sets standards for the precision of bearing balls.

What to Look for When Choosing a Precision Ball Screw

What to Look for When Choosing a Precision Ball Screw

Dec 09 2009 · Strict process control when grinding the ball shaft and ball nut raceways ensures that the contact angles will meet design specifications. Good control of the grinding process should allow for a small range of ball sizes from the nominal. A large ball range from nominal allows the contact angle to shift and can result in decreased life.

Quad Brand Ground Rubber BallsMinnesota Rubber and Plastics

At pressures greater than 120 psi there is a tendency for ground balls to become stuck in the ball seat (checking orifice). If this occurs often it can damage the ball eventually causing the ball to extrude through the orifice. As a "rule-of-thumb " the diameter of a check ball should be at least three times the diameter of the flow orifice.
