Case study that the bearing rubs process technology and trace or burns


31st July 2013 Bearing Technology 0 Comments
The case study that the bearing rubs process technology and trace or burns: The work piece appearance is reproduced and will often be burnt in grinding to burn the surface of the trace work piece, burn several kinds of types, first, burn in the direction that the emery wheel is processed, black dull plaque; Second, take the form of the lines or lines of make-and-break. The surface of the work piece is burnt in the course of rubing and processing, sum up and have the following reasons: 1.The emery wheel is too hard or too detailed organization of graininess is too dense; 2.The feeding ...

Bearing heat treatment technology and equip ‘ Three)


31st July 2013 Bearing Technology 1 Comment
The water based quenching medium is aqueous solution composed of organic polymer, corrosion inhibitor and other additive. Get different cooled characteristics through changing organic polymeric type and density, with suitable for different the intersection of bearing and part, quench, cool, require. In the course of quenching cooling, the organic matter adheres to the surface of the part, can reduce the part and quench the danger that fractures, and does not produce the soot, it is convenient to wash, pollution-free, it is the developing direction of the quenching medium. It is a medium ...

Bring the custody of spherical bearing and 29244 type parameters outside the seat


31st July 2013 Bearing Technology 0 Comments
Take the custody of the spherical bearing outside seats: Bring spherical bearing coat with right amount of rust-preventive oil and use, antirust wrapper when being dispatched from the factory outside the, so long as packaging this destroy, bring quality of spherical bearing receive assurance outside the. But while preserving temporarily, draft it on condition that it is about 20 ℃ that the humidity is lower than 65% of the temperatures, leave it in and is higher than the ground 30cm shelf. In addition, keeping the place should avoid penetrating the sunshine directly or touching with the ...

2.Frock apparatus that the regular martensite quenches The frock apparatus that the Chinese bearing trade regular martensite quenches at the present stage is different, can be divided into the oxidation furnace, controlled atmosphere furnace and vacuum furnace of the unprotected medium protecting mediums. About 25% that the oxidation furnace of the unprotected medium accounts for the heat treatment of the bearing and equips, ones that protect the medium do not have about 50% that oxidation furnace accounts for the heat treatment of the bearing and equips fewer, about 20% that the controlled ...

Magnetic bearing applied ‘ One)


31st July 2013 Bearing Technology 0 Comments
The magnetic bearing supports the load or suspends a kind of supporting form of the trochanter by magnetic force. This kind of bearing is developed quickly in recent years, especially in high speed, low friction drag, high low Warm and application under the vacuum environment. The magnetic bearing has its unique superiority compared with other supporting forms, there is a development prospect very much. First, characteristic and classification 1.Characteristic Friction is small, low power dissipation, can realize ultrafastly that operate. It is high to support the precision, have steady ...

Supply NSKNJ308E cylindrical roller bearing


31st July 2013 Bearing Technology 0 Comments
1. Whether roller and ball track or repair the blade connection for the blade connection, radial bearing capacity is great, suitable for bearing heavy load and shock load. [2]2. The coefficient of friction is small, suitable for the high speed, the terminal rotational speed is close to the ball bearing of major groove. 3. N-type and NU type can move axially, can adapt to the axle caused by thermal expansion or installation error and change of outer cover relative position, can make free ends to support and use. 4. The processing of the countershaft or seat hole is expected relatively ...
