About this item
  • PREMIUM 304 STAINLESS STEEL: Crafted from high-grade 304 stainless steel, these bearing balls offer exceptional resistance to rust and corrosion. This durable material ensures long-lasting performance in both indoor and outdoor environments, even when exposed to moisture or oxidation.
  • G100 HIGH-PRECISION GRADE: Each ball is manufactured to G100 precision standards, featuring a highly polished surface and uniform sphericity. This high level of accuracy minimizes friction in mechanical bearings and provides a consistent, aerodynamic flight path for slingshot and catapult ammunition.
  • COMPREHENSIVE SIZE SELECTION: We offer a full range of diameters to meet any technical requirement, including 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 9mm, 9.5mm, 10mm, 11mm, and 12mm for a perfect fit in any application.
  • VERSATILE MULTIPURPOSE UTILITY: These precision spheres are ideal for repairing flange bearings, bicycle components, and household appliances. They also serve as professional-grade agitators for mixing paints or chemicals and provide heavy-duty, high-impact performance for recreational shooting.
  • FLEXIBLE PACK QUANTITIES: Tailor your order to your specific project needs with convenient pack sizes of 1, 5, or 10. Whether you are performing a single repair or stocking your workshop, these stainless steel balls deliver the reliability and quality you expect.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
