Ball bearings, roller bearings and needle roller bearings

Ball taper roller bearing  roller bearings and needle roller bearings. High speed, load is small, requiring high precision rotation should use ball bearings; load is large roller bearings should be selected; loading large radial dimensions should be selected when they restricted needle bearing. Radial bearing rings of the inner and outer ring, inner ring and the shaft sleeve and often with the shaft rotates, the outer ring mounted in the bearing bore. Rolling rolling along the raceway rings, separated by the cage, to avoid friction between. Thrust bearings are divided into a tight circle and live ring in two parts. Tight circle and sleeve tight, live ring bearing in the bearing housing. Rings and rolling body with high strength, good wear resistance bearing steel, surface hardness after quenching should reach HRC60 ~ 65. Cage mostly made of mild steel stamping, and some copper alloy, bakelite cloth or plastic. Basic types listed in the table produced in China basic types of rolling bearings. Various types of rolling bearings is divided into B, C, D, E, G5 a precision. B is the highest accuracy level. G is the general accuracy level, the most common. High speed, there are strict requirements for precision rotation of the spindle, high precision bearings should be used, such as precision lathes, milling machines, boring, grinding grinding, aircraft engine, turbocharger, precision instruments selected C, D grade; coordinate boring machine, High-speed grinding elect B, C grade. Rolling easy maintenance, reliable, good starting performance at moderate speeds higher carrying capacity. Compared with the sliding bearing, radial bearing a larger size, poor damping capacity, high speed, low life sound bigger. Rolling in the radial bearings (mainly radial force) usually consists of inner and outer rings, rolling and rolling element cage four parts. Inner sleeve in the journal together with the shaft rotates, the outer ring mounted in the bearing bore. In the inner and the outer periphery of the inner periphery of the outer ring are formed with raceway. When the relative rotation of the inner and outer rings, the inner and outer rings of the rolling element raceway, are separated by the cage, to avoid friction. Thrust bearings are divided into a tight circle and live ring in two parts. Tight circle and sleeve tight, live ring bearing in the bearing housing. Rings and rolling elements commonly used high strength, wear resistance, good bearing steel, surface hardness after quenching should reach HRC60 ~ 65. Cage mostly made of mild steel stamping, copper alloys can also be used bakelite cloth or plastic manufacturing

Henan University of Technology is located in the historical and cultural city

SKF delegation once again visit Henan University of Technology
Henan SKF Precision bearing sales center there is news that today one of the world's largest bearing company - SKF Group , recently sent a delegation to visit again , Henan University of Technology ( HKUST referred River ), SKF delegation and the river HKUST the leadership of Mechanical Engineering on personnel training, joint bearing basic technology research and academic exchanges , and business products and technology demonstrations and other issues were widely discussed and reached consensus on a number of intentions and . We follow Henan SKF angular contact ball bearing distributor SKF Group sales center to find access to Henan University of Technology on behalf of the whole process .
 Henan University of Technology is located in the historical and cultural city , the modern industrial and tourist city of Luoyang . Last December , SKF delegation paid a visit to Henan University of Technology , the SKF Group re-visit the river HKUST delegation SKF Group Human Resources Director Asia and Ms. Tina Jiang SKF Bearing China Ltd. , Henan tribology and lubrication experts University professor Dr. George TYWan line of five people . SKF Group Asia Director of Human Resources Ms. Tina Jiang introduced the SKF Group and the Chinese company's organizational structure, management philosophy, corporate culture and human resource development . And listen to the river HKUST College of Mechanical and Electrical Engineering , bearing professional personnel training and the introduction of basic scientific research . The two sides exchange visits of experts to give lectures , scientific and academic cooperation , personnel training and other aspects to achieve cooperation and consensus.

Dalian NTN Bearing : NTN new wheel bearings

 Introduction of new products , is a business motivation, we have learned from the Dalian NTN bearings distributor , recently, Japan NTN Bearing Corporation in cooperation with the French SNR NTN developed a new type of wheel bearings , the biggest feature is the built- divided into two level switching signal resolution rotation sensor , which can detect a good speed , control ABS and ESC ( anti- skid device ) . Here we follow the Dalian NTN Bearing NTN distributor to learn about this new wheel bearings .
 New wheel Precision bearing NTN working principle and structure :
 New Wheel Hub Bearing NTN works: when the car in case of low and medium -speed , high-resolution signal can be 40 times the original wheel speed detection accuracy . Can be detected by standard vehicle only 1mm movement , control of the vehicle when the best time to be able to control the braking force. In the ABS control for the main purpose of the high speeds , the use of low-resolution signals to reduce the burden of data processing . Development of products high resolution signal output A -phase and B-phase two kinds of pulses , these pulses output by observing the situation , be able to detect the vehicle is moving forward or bearing manufacturer . This can be used to detect whether the start ramp and automatic slip car parking and so on. Wheel speed sensor using a sensor ( fixed side ) detected at the same intervals on the circumferential direction are alternately magnetized N pole and the S pole magnetic encoder ( rotation side ) of the magnetic pole changes , as the wheel rotation signal for vehicle control. Reduced rotation signal , which is to improve the resolution , will be able to more finely control the vehicle .
 New Wheel Hub Bearing NTN structure : NTN and SNR using the original magnetic encoder developed a resolution of up to 40 times the original magnetic sensor , and in 2007 developed the magnetic sensors embedded in the " rotation sensor with high resolution hub bearing " . Since high resolution and high speed data processing burden, thus switching the resolution added functionality .
