Buying Guide

Choose material for application

Chrome steel offers high hardness and wear resistance for bearings, while brass reduces corrosion and is non-sparking for fixtures and gauging

Match ball size to fit

Select the correct diameter—options here span about 5/8" up to 5"—to ensure proper seating, clearances, and contact geometry in your assembly or test setup

Check roundness and grade

Look for stated precision or inspection data; higher roundness and tighter grade numbers yield better load distribution and more consistent measurement results

Consider single vs. multi-pack

Buying individual large balls is common for display or specific bearings, while multi-packs (25 pieces of smaller sizes) are better for stocking, prototyping, or batch use

Evaluate corrosion and finish

Chrome-plated steel provides a smooth, hard finish for rolling contacts; brass is naturally corrosion-resistant and easier to machine or mark
