Product Description

Bearing Steel Tube is a small to medium sized hot or cold rolled seamless hollow cylindrical section which is used for producing general antifriction bearing ferrule. It is manufactured by using top quality steel which is added with elements like chromium, nickel, zinc etc. as an alloy to enhance the physical and chemical properties and make the product suitable for heavy loading and high speed operations. Bearing Steel Tube offered by us is capable to withstand extreme pressures and friction forces to prevent the rupture and wearing of the components. This machine element can be used in various heavy machines like combustion engine, rolling machine, electric motor car, mining machinery and power transmission units.

FAQs of Bearing Steel Tube:

Q: How are bearing steel tubes with grades like GCr15, SUJ2, and 100Cr6 manufactured?

A: These tubes are produced using cold drawn techniques, followed by quenching and tempering heat treatments to achieve the specified hardness (HRC 58-65). Precise straightness and surface tolerance are maintained throughout the process, ensuring reliable dimensional accuracy and performance.

Q: What are the main applications for these bearing steel tubes?

A: They are primarily used in the automotive, engineering, machinery, and general industrial sectors. Their high strength and wear resistance make them suitable for components like axles, shafts, and parts subject to heavy mechanical loads.

Q: When should I choose welded versus seamless bearing steel tubes?

A: Seamless tubes are recommended when higher strength and uniformity are required, particularly for critical or high-pressure applications. Welded tubes are suitable for general structural and less demanding applications. The choice depends on your projects specifications and stress requirements.

Q: Where are these bearing steel tubes commonly produced and supplied from?

A: Most of these tubes are manufactured, supplied, and exported from China, adhering to leading international standards such as ASTM, DIN, JIS, and GB. Chinese distributors offer global delivery and robust supply chains.

Q: What is the benefit of the quenching and tempering heat treatment used in these tubes?

A: Quenching and tempering enhance the steels hardness and strength while also improving toughness and resistance to wear. This specific heat treatment ensures the tubes maintain performance even under heavy operating conditions.

Q: How are the tubes packaged and protected during transit?

A: The tubes are bundled securely with steel strips, wrapped in plastic, and fitted with plastic end caps. This ensures protection against physical damage, corrosion, and dirt during shipping and handling.
