6.0mm Chrome Steel Balls – High-Precision Bearing Steel Balls

Our 6.0mm chrome steel balls are manufactured from high-grade AISI 52100 chrome alloy bearing steel, also known as GCr15, 100Cr6, SUJ2 or 1.3505. This is the industry-standard material for precision rolling elements, and our 6.0mm bearing balls are through-hardened and finely finished to deliver outstanding dimensional accuracy, hardness and wear resistance. Designed to minimize friction while maximizing load capacity, they are the trusted choice of original equipment manufacturers and aftermarket buyers around the world.

• High hardness and wear resistance: through-hardened to HRC 60-66 for long-lasting, dependable performance.
• Tight tolerances: available from G10 to G1000 to match your exact application requirements.
• Excellent surface finish: polished surfaces reduce friction, noise and vibration in operation.
• Proven material: AISI 52100 / GCr15 chrome steel with a long track record in the bearing industry.
• Factory-direct pricing: consistent quality at competitive export prices, with flexible order quantities.
• Customized packaging: available oiled or dry, packed in plastic bags, cartons, drums or as requested.

6.0mm chrome steel balls are widely used in deep groove ball bearings, angular contact bearings, thrust bearings, ball screws, linear guides, casters, wheels, pulleys, conveyor systems, pumps, compressors, automotive components, precision instruments, bicycles and many other industrial products. Their dimensional stability and fatigue resistance make them especially suitable for applications that demand low noise, high speed and long operating life, giving your products a competitive edge in the market. They also perform reliably under continuous operation and fluctuating loads.

Strict Quality Control

Every batch of our 6.0mm bearing balls is inspected at each stage of production, from raw wire drawing to cold heading, heat treatment, grinding and final lapping. Final inspection covers diameter, roundness, surface quality, hardness and other key parameters, and detailed inspection reports are available upon request for your quality audit. Our factory operates under an ISO 9001 quality management system to ensure consistent, reliable product quality on every shipment.
