The principle of choosing rolling bearing steel please detailed said jiaxing bearing small make up for you

There is rotational, have HRB bearing ( ) Selection principle of rolling bearing steel jiaxing bearing the author detailed for you said, please. Jiaxing bearing group sales co. , LTD. ( The company) Is jiaxing bearing factory set up in the spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong cash supply ability. In the design and manufacture of rolling bearings, general according to the following principles to select bearing materials. Working temperature under the normal temperature of bearing, the use of chromium bearing steel. Working temperature higher than 150 ℃ lower than 250 ℃ using chromium bearing steel, also to go through a special heat treatment ( 200 ℃ or 300 ℃ tempering) 。 Under impact load, the size of bear strong impact load bearing, generally do not use chromium bearing steel, most high quality carburizing steel, resistant to shock tool steel or quenched and tempered steels. Contact with the medium used in corrosive medium bearing must be used with good corrosion resistance of corrosion resistant steel or alloy steel manufacturing. Choice depending on the type of bearing structure of the bearing parts structure is complex, such as the outer ring installation guard, and bear high impact load, appropriate USES carburizing steel processing performance is good; Stamping outer ring needle roller bearing can be adopted the euro and low carbon steel (10 Plasticity is good, suitable for cold stamping processing) ； Tilting mechanism and operating mechanism on the use of joint bearing, can be used with excellent cold plastic deformation properties of GCr15, 9 cr18, 9 cr8mo and alloy structural steel cold extrusion molding. According to the bearing fatigue life and reliability requirements to choose bearing fatigue life and reliability, to a certain extent, depends on the steel purity and uniformity. For general use, use more open hearth acidic or alkaline the ordinary bearing steel smelting electric furnace. With the continuous improvement of smelting method, produced the current remelting, vacuum smelting, electron beam smelting furnace, such as a new mode of smelting, tempered by way of the bearing steel bearing, the life also improved accordingly. Suitable for bearing fatigue life and reliability have special requirements, such as railway vehicle axle box bearings, aircraft engine bearing spindle bearings and navigation system, etc. In addition, also should be taken into account when choosing steel grade steel processing performance, supply and domestic resources and so on.
