Bearing steel balls

Bearing steel has high and uniform hardness and properties, as well as a high elastic limit. It has very strict requirements for the uniformity of the chemical composition of bearing steel, the content and distribution of non-metallic inclusions, and the distribution of carbides, making it one of the most demanding steel grades in all steel production.

Bearing steel balls, also known as chrome steel balls, chromium steel balls, or ball bearings, are mainly used for bearing production and assembly. They are important components in bearing components and play a crucial role. Of course, bearing steel balls are also used in various other machinery industries, with their main feature being high hardness, HRC60-65. Large-diameter steel balls HRC58-63 have a long service life.

Application Areas:

GCR15 bearing steel balls are widely used in high-speed, low-noise bearings, bicycles, motorcycles, automobiles, slide rails, universal balls, luggage, electronics, and can also be used to grind other media.

Features:

Excellent surface quality, strong properties, high hardness, and strong load capacity. Magnetic and ferritic steel, oil-based packaging, high hardness.
