high-pressure balls

Shteinen Balls

Sphericity: the better the grade of the ball the closest to a perfect sphere a ball is made. Sphericity of a ball is critical for valve applications where the liquid passes through the valve requires a tighter application to the tube.

Surface Integrity: Tribology of a ball is critical to the surface-to-surface and/or surface-to-lubricant circumstances. Precision balls are required to have a better surface coefficient of wear such that the ball has limited surface defects.

Diameter: the better the grade of the ball, the tighter the ball diameter tolerance. Diameter is critical for quiet bearings.
