Quality taper roller custom bearings manufacturer and supplier
Taper roller Roller bearings manufacturer in China? Tapered roller bearing type belongs to the separation bearing,have tapered roller bearing inner and outer race.According to these bearings on the column number of the roller is divided into single row,double row and four row circular cone roller bearings of different structure.Is mainly used to bear the joint mainly consistent of radial load and axial load.Compared with the angular contact ball bearing,large carrying capacity,limit rotational speed is low. Read even more information on double taper roller bearing.
Ball screw pair is to convert rotary motion to linear motion, or convert linear motion into rotary motion of the ideal product.Ball screw pair by screw, nut, reverse gear and ball bearing, ball screw pair is the function of rotary motion into linear motion, or convert torque into axial force repeatedly, at the same time combines the characteristics of high accuracy, reversibility and high efficiency. Ball screw pair with high accuracy, reversibility and high efficiency etc., this is the further extension and development of the trapezoidal screw, the significance of the development is the trapezoidal screw sliding action into a rolling action.
Oilless bearing is a kind of both metal bearing characteristics and bearing characteristics of novel lubrication bearing lubrication system, the load matrix, and the special formula of solid lubricating materials lubrication.It has high bearing capacity, impact resistance, high temperature resistant, self-lubricating ability etc., especially suitable for overloading, low-speed, reciprocating or swing, difficult to lubrication and oil film formation, not afraid of the water and other acid erosion and erosion.
One-way bearing is free to rotate in a direction, and locked in another direction of a bearing.One-way bearing is also called the overrunning clutch, just according to different industries, the effect is different.One-way bearing metal shell, contains a number of roller, needle or ball, and the rolling (hole) of the shape that it can only scroll in one direction, while in another direction will produce very big resistance (the so-called “one-way”). Powder metallurgy one-way bearing by moulding and sintering process the metal powder (or the mixture of metal powder and nonmetal powder) made products of technology.In the study of the characteristics of powder and process variation characteristics, on the basis of the corresponding technical process, changing the shape of powder, performance, and their organization structure as to adapt to the different needs of bearing products.

Released on December 20, 1984 of the People’s Republic of China machinery industry standard: JB / 2300-84 the rotary bearing type, basic parameters and technical requirements, composed mainly of machinery and electronics industry of tianjin engineering machinery research institute, xuzhou hering slewing bearing factory is responsible for drafting, the country then issued standard of construction machinery in 1991: JB36.1-36.3-91, released in 1999 and 2011 successively new machinery industry standard JB / 2300-1999 and JB / 2300-2011. Slewing bearing, is a kind of comprehensive load to bear a large bearings, can withstand the larger axial and radial load and tilting moment.
Treatment method: in order to solve the soft spot and other defects of medium and large varieties of bearing ring, the composition and performance of quenching oil should be determined. If it is not satisfactory, it should be replaced by fast quenching oil in advance, so as to enhance the quenching ability of quenching as medium and improve quenching and cooling conditions.Strict tempering process.In view of the varieties with many fracture phenomena, secondary tempering is carried out after rough grinding of the rings, which can further stabilize the structure and size of the rings, reduce the grinding stress, and improve the performance of the grinding metamorphism layer. Bearing rings often fracture in the use of the phenomenon, which mainly has three forms, respectively: fatigue fracture, overload fracture and thermal fracture.
The effort pays off. With the success of the first self-lubricating bearing, China’s self-lubricating bearing technology is becoming more and more perfect, and the service life is getting longer and longer. Since its development, the service life of self-lubricating bearings produced in China has reached more than 300 hours, ranking among the top in the world. Longxi has passed the most rigorous A-standard bearing certification of the NAVAIR laboratory, the most authoritative experimental organization in the field of self-lubricating bearings, and is the only Chinese bearing company that has obtained its certification so far.
