100Cr6 bearing steel tube is a high-carbon chromium steel tube used for bearing sleeves, precision mechanical parts and wear-resistant tubular components. It provides high hardness and good fatigue resistance after heat treatment. The tube can be supplied in different outside diameters, wall thicknesses and lengths, with cutting and further processing support for bearing and machinery applications.
Materials can be cut to required sizes according to customer specifications or project needs.
Different surface finishes can be supplied according to product type and application requirements.
Processing services such as cutting, machining, heat treatment or surface finishing can be arranged upon request.
Products are packed for international transportation with flexible delivery support for global buyers.
For bearing rings, precision mechanical sleeves, and wear-resistant tubular parts.
Suitable for the machining of bearing inner and outer rings, rolling bearing races, precision sleeves, mechanical bushings, wear-resistant rings, and annular components for automotive and industrial equipment. Ideal for applications requiring high dimensional stability, wear resistance, and fatigue life.| Item | Typical Information |

Q: What is 100Cr6 bearing steel?
A: 100Cr6 (Material No. 1.3505) is a high-carbon chromium alloy steel widely used for anti-friction bearings in European standards. It contains approximately 1.0% carbon and 1.5% chromium, providing through-hardening capability and excellent wear resistance after heat treatment.
Q: What standards does your 100Cr6 bearing steel tube comply with?
A: Our 100Cr6 bearing steel tube is manufactured and tested in accordance with EN ISO 683-17 (Heat-treated steels, alloy steels and free-cutting steels — Part 17: Ball and roller bearing steels) and DIN 17230. Full MTC is provided with every shipment.
Q: What sizes and forms are available?
A: We supply 100Cr6 seamless bearing steel tubes with outer diameter ranging from 10mm to 250mm and wall thickness from 2mm to 30mm. Available forms include hot-rolled, cold-drawn, and precision finished tubes. Cut-to-length service is available per customer specification.
Q: What are typical applications of 100Cr6 bearing steel tube?
A: 100Cr6 tube is primarily used for manufacturing bearing inner and outer rings, bearing races, bushings, roller sleeves, and precision cylindrical components requiring high hardness, dimensional accuracy and wear resistance.
Q: How does 100Cr6 compare to other common bearing steel grades?
A: 100Cr6 is the European equivalent of AISI 52100 (US), SUJ2 (Japan) and GCr15 (China). All are high-carbon chromium bearing steels with very similar composition and performance, designed for rolling-element bearing applications.
