The Structure and Character of Cross Roller Bearing ZYS precision cross roller bearing, the inner structure of which adopts the vertical and cross arrangement of cylindrical rollers with 90°, can bear radial load, double-direction thrust loads and overturning moment at the same time. Combined with its high rigidity, crossed roller bearing can be applied to the joints and rotating parts of industrial robots, rotary tables of machining centers, rotating parts of manipulators, precision rotary tables, medical equipments, measuring instruments, IC manufacturing machines, etc. http://www.zysbearing.com/precision-bearings/cross-roller-bearings.html

Special Angular Contact Ball Bearing Unit There are three types of the special angular contact ball bearing unit produced by ZYS: 1. The super thin-wall bearings with one inner ring and two half outer rings; 2. The bearings with one outer ring and two half inner rings. They have super thin-wall bearings, standard bearings and heavy bearings series. 3. The bearings with one outer ring (three raceways), one small inner ring, and one large outer ring. They are bearings with flange mounting and have standard bearings and heavy bearings http://www.zysbearing.com/bearing-manufacturing-machines/

 Ball screw bearings adapt to various purposes for bai, and du provides a wide range of standardized products. Widely used in machine tools, the ball circulation dao methods include circulating duct type, circulator type and end cap type. Preloading methods include positioning preloading (double nut method, position preloading method) and constant pressure preloading. The appropriate type can be selected according to the purpose. The screw has high-precision grinding precision ball screw (precision is divided into 6 grades from CO-C7) and cold-rolled ball screw bearing formed by high-precision cold rolling (precision is divided into 3 from C7-C10) Levels). In addition, in order to cope with the urgent need for delivery by users, there are finished products that have been processed on the end of the shaft, semi-finished products and cold rolled ball screw bearings that can be freely processed on the end of the shaft. As the peripheral parts of this bearing, the screw support unit, n...

 The correct selection of high-performance bearings for machine tools should be based on: 1. The accuracy and load of the machine tool select the accuracy of the bearing and the size of the bearing; 2. The rotation speed of the machine tool transmission shaft selects the limit rotation speed of the bearing; 3. Select the type and installation form of the bearing for the force condition of the machine tool drive shaft; 4. The special structure of the bearing is selected for the special requirements of the machine tool transmission. http://www.zysbearing.com/precision-bearings/high-precision-angular-contact-ball-bearings.html

 Bearing vibration measuring instrument is generally composed of driving device, sensor, amplifier, filter, measurement display and self-calibration system. The driving device drives the inner ring and rolling elements of the bearing to be tested. The radial vibration acceleration signal generated by the bearing at this time is picked up by a piezoelectric acceleration sensor and converted into a charge signal to be amplified by an amplifier and filtered by a band-pass filter It is sent to the measurement display circuit, and the acceleration decibel value is displayed through the RMS meter and the PEAK meter, and the performance of the bearing is characterized through various forms such as oscilloscope and loudspeaker. http://www.zysbearing.com/bearing-parts-measuring-instruments/s95-single-ball-vibration-measuring-instrument.html

Railway bearing s refer to bearings used in the rolling industry, that is, rolling non-ferrous metals, ferrous metals and non-metallic products, at the roll diameter of the rolling roller system and on . the drum. Four-row cylindrical roller bearings are usually used to bear radial loads, thrust roller or thrust ball bearings and radial angular contact ball or radial roller bearings to bear axial loads. It has the advantages of large load capacity, high limit speed, high precision, separable inner and outer rings and interchangeability, easy processing, low production cost, and easy installation and disassembly.

Elastic sheet gas dynamic pressure bearings ( Thin section bearing ) are more and more widely used in aerospace and civil high-speed machinery (such as gas turbochargers, high-speed centrifuges, oxygen generators, air-jet spinning) because of their high-speed dynamic performance. Yarn machine, liquid rocket propulsion system, rail transporter) and other fields. Their uniqueness lies in their outstanding performance, despite the weight and space constraints. Minimal, the usual square cross-section allows high precision of the mechanism.
