We produce all kinds of balls, complete materials, reliable quality. Widely used in bearing chemical industry, hardware, minerals, automotive industry, instrumentation, medical, motorcycle, bicycle and other fields.
Bearing steel ball
Widely used high carbon chromium bearing steel, also known as chromium steel ball. The GB brand is GCr15, characterized by high hardness, good wear resistance, high elastic limit, high contact fatigue strength, good cold and hot processing performance, hardness HRC60 or so, magnetic, itself is not waterproof or rust-proof, the need for appropriate anti-rust protection measures. High precision G10 grade bearing steel ball is widely used in precision machine tool screw slider high-speed silent bearing and other fields Q235 carbon steel ball also known as A3 steel due to moderate carbon content, good comprehensive performance, strength, plasticity and welding and other properties have been better matched, widely used. Hardness HRC55-58 or so, magnetic, itself is not waterproof and rust resistant, the need for appropriate anti-rust protection measures.
304 stainless steel
Is widely used on the market a national recognized food grade environmental protection stainless steel ball, GB grade OCr18Ni9, hardness ≤200HV. Features: good anti-rust, anti-corrosion properties, low hardness, no heat treatment hardening phenomenon, easy to process. The typical representative of Austenitic steel is generally non-magnetic, but it will be magnetic after the photosphere and can be demagnetized.
316L stainless steel
Is a relatively demanding product, GB grade 0cr17ni12mo2, usually used in special industries such as medical equipment, chemical, aviation, aerospace. Austenitic steel, HRB95, suitable for higher anti-corrosion requirements of the industry, the performance is better than 304 stainless steel ball, with stronger anti-rust and anti-corrosion properties, easy welding, excellent polishing, more suitable for higher surface requirements of the industry.
420 stainless steel ball
It is usually used in industries that require high precision and anti-rust performance: motorcycle parts, pulleys, stainless steel bearings, plastic bearings, crafts, valves, oil. The representative of martensitic steel, commonly known as stainless iron, magnetic, GB grade 20r13/3Cr13 has good anti-rust performance, high hardness HRC50-55.
440C stainless steel ball is usually used for precision, rust resistance, wear resistance, hardness, are high requirements of the industry, GB grade 9Cr18Mo Martensitic steel, magnetic, high production process requirements, HRC≥58, hardness close to the bearing steel ball.
Carbide ball (steel ball)
(generally combined with gold, weak magnetic) can be customized non-standard size, with high hardness and wear resistance, heat resistance, corrosion resistance, basically unchanged at 500 ° C temperature, bending resistance, the use of harsh environment, alloy ball wear resistance is dozens of times the steel ball, hardness HRA93. Widely used in bearings, instruments, instruments, various hardware punching and squeezing holes, die casting, valves, grinding, hardness tester, pump valve, petroleum, chemical, metering equipment.
Is not quenched treatment, low hardness easy secondary processing, widely used in drilling, tapping, welding, decoration and other purposes. Magnetic, not waterproof, not rust, hardness HB is 169-200, HRC<20
Pure copper ball
Good electrical conductivity is widely used in carburetors, switches, valves, auto parts and other products, its hardness HRC≤26
It has good ductility, high reflectivity, oxidation resistance, electrical conductivity, thermal conductivity, heat resistance, low temperature resistance, nuclear radiation resistance and sound absorption. Light weight, corrosion resistance, low hardness, non-magnetic, used in hardware, mechanical engineering, decoration, welding and so on.
Zirconia ceramic ball (ZR02)
At normal temperature, it has high strength and toughness, good wear resistance, high temperature and corrosion resistance, high stiffness, non-magnetic conductivity and electrical insulation. At 600 ° C, the strength and hardness are almost unchanged, and white is the natural color of zirconia ceramic balls. Suitable for bearings, seals and other high precision machinery industry fields
Silicon nitride ceramic ball (SI3N4)
59% lighter than the steel ball reduces the centrifugal force, rolling and wear of the channel when the bearing is running at high speed and accelerated, the elastic modulus is 44% larger than that of steel, the deformation is greatly reduced than that of the steel ball, the hardness HRC reaches 78, the high temperature resistance, never rust, the strength can be maintained to 1200℃ without falling, and the heat will not melt into the melt. Is one of the world’s hard material materials, can work under oil-free lubrication conditions, more chemical corrosion resistance than steel non-magnetic: electrical insulation, can be used for a variety of bearing with extreme performance requirements: can also be used for chemical pumps, high temperature pumps, metering pumps used as valve balls, measuring balls can also be widely used in chemical, metallurgy, medical, food, oil fields, electronics and other industries.
