Bearings are usually made of high carbon steel GCr15; commonly known as bearing steel. In addition, there are carburized bearing steel, stainless bearing steel, high temperature bearing steel, medium carbon impact bearing steel; today's latest bearing information is ceramic overall In terms of bearing material quality, there are six major requirements; tumbling touch fatigue strength is second; raw material purity is high; after heat treatment, high uniform hardness can be obtained; high wear resistance is five; scale stability is good; Corrosion resistance and chemical stability as bearing data using chrome steel, chrome molybdenum steel, nickel chrome molybdenum steel, quenching and quenching; making steel from the appearance to the appropriate depth has a hardened layer. With appropriate hardening depth, fine Arrangement, suitable for the appearance of hardness and the hardness of the carburizing bearing; the bearing has better impact resistance than the bearing bearing steel; the chemical composition of the steel for ordinary carburizing bearings.

Pipe Cutting Machine

The company research and development of double servo precision automatia pipe cutting machine, suitable for all kinds of pipe material, and the soild pipe cutting, especially suitable for the mass production of the enterprise, the machine has high production efficiency, good rigity,high precision(make sure the error within 5 wire), one feed can cut more piece.The machine adopts PLC control, the most advanced double servo positioning system,hydraulic clamping feeding. Make up the previous machine of rust, bending the disadvantages of insufficient material, eliminate waste.

The machine has warning for borken blades/no material/remain material in insufficient, high production efficiency,and can achieve more than one machine management.The pipe cutting machine adopts the cross roller guide rail, with good rigidity, small rolling friction, long life, high precision etc.Vertical and horizontal drag plate with double feed servo system, a fast response, stable feeding. The Tube pipe cutting machine use special bearings steel cutter chip, easy and quick to change cutter.The mahcine can be divided into three side Chamfer Pipe Cutting Machine and od turning Steel Pipe Cutting Machine.
