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.
