Solid Ball

Overview

A ‘solid’ ball is machined from 100% compact casting or forgeing. The opposite is a ‘hollow ball’ where the ball is constructed with an inside hollow, usually by two metal spheric halves joined together, with or without inside walls or ribs as reinforcement.

The hollow-ball concept is used to save weight and/or money in materials and machining.

If there is a choice between solid and hollow ball for the same application, the solid ball is normally considered as the ‘best cost/lifetime’ solution. Reasons given are less risk for construction, wear, material and fabrication failure over time. The difference between the two could however be from ‘practically insignificant’ to ‘very high’, all depending on quality, QA for product and application circumstances. Note: for some very large constructions solid ball would not be practical.
