Loose High-Precision Steel Bearing Balls — Solid Metal Balls for Every Application
Finding the exact diameter bearing ball for a repair, prototype, or mechanical assembly can be a frustrating experience when standard packs force you to buy sizes you don't need. Whether you're a machinist, hobbyist, or maintenance technician, these loose high-precision steel bearing balls let you select exactly the diameter and quantity you need — from a single piece to bulk packs of 1,000.
Each ball is a solid steel sphere machined to tight tolerances. The diameter range spans 1mm (≈0.039 in) to 29.6mm (≈1.165 in), covering both metric and inch-equivalent sizes. Balls are available in a wide selection of diameters including 1mm, 1.2mm, 1.5mm, 1.588mm (1/16"), 1.6mm, 1.8mm, 2mm, 2.381mm (3/32"), 2.5mm, 2.778mm (7/64"), 2.8mm, 3mm, 3.175mm (1/8"), 3.2mm, 3.5mm, 3.969mm (5/32"), 4mm, 4.1mm, 4.5mm, 4.763mm (3/16"), 4.8mm, 5mm, 5.2mm, 5.4mm, 5.5mm, 5.556mm (7/32"), 5.953mm (15/64"), 6mm, 12.5mm, 12.7mm (1/2"), 20.5mm, 20.638mm (13/16"), 21.43mm, 21.431mm, 22.225mm (7/8"), 22.5mm, 22.8mm, 23.5mm, 23.813mm (15/16"), 24.5mm, 24.606mm, 25.1mm, 25.2mm, 25.3mm, 25.4mm (1"), 25.5mm, 25.8mm, 26.2mm, 26.5mm, 27.5mm, 28.57mm, 28.575mm (1-1/8"), 29.2mm, 29.3mm, 29.5mm, and 29.6mm.
These solid metal balls are widely used in bearing replacement and maintenance, ball-end linkage assemblies, valve seats and check valves, decorative metalwork and jewelry making, and precision jig and fixture construction. Their consistent roundness and surface finish make them suitable for load-bearing, rolling, and sealing applications across DIY and light industrial contexts.
