    Precision tapered roller bearings In some heavy-duty machine tool applications that have certain speed requirements, such as grinding of forging parts, turning machines for oil pipelines, heavy lathes and milling machines, it is an ideal solution to choose precision tapered roller bearings. Because the rollers of tapered roller bearings are designed with linear contact, it can provide high rigidity and load for the spindle; in addition, tapered roller bearings have pure rolling bearing design, which can reduce the torque and heat in the bearing operation to ensure the speed and accuracy of the spindle. Since tapered roller bearings can adjust the axial preload (clearance) during installation, this allows customers to better optimize bearing clearance adjustment throughout the life of the bearing. https://www.zys-bearing.com/Bearings/

Application of thin section bearings: ZYS thin section bearings have three types: deep groove ball bearings, angular contact ball bearings and four-point contact ball bearings. The inner and outer rings of thin section ball bearings are very thin and require precision turning and grinding to achieve the required tolerances.ZYS thin section ball bearings are widely used in aerospace, astronomical instruments,fixtures and fixture equipment,food processing equipment,glass processing equipment,rotation table,packaging equipment , machine tool, medical equipment, optical scanning equipment,satellite and communication equipment, robot, textile machinery, pipe cutting machine, semiconductor manufacturing equipment, sorting equipment,etc. http://www.zysbearing.com/precision-bearings/thin-section-bearings.html

  High-frequency grinding spindles 1. Tight structure, high mechanical effciency, low noise, low vibration, high precision. 2. Stable running, weak impaction, prolong bearing life of the spindles. 3. High speed, high dynamic and static precision, high stability. 4. The stepless variable speed in the range of the rated running speed is avaiable to suit the request of various conditions and loads. 5. Driving control skill makes accurate stop, accurate position and accurate speed suitable for therequest of processing center and other numerical control machine tools. http://www.zysbearing.com/spindles/high-frequency-grinding-spindles.html

 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

 Cross roller bearing, because the divided inner ring or outer ring is fixed with the cross roller ring after the rollers and spacers are installed to prevent separation from each other, so operate when installing the cross roller ring simple. Since the rollers are arranged in a cross, only one set of cross roller rings can bear loads in all directions. Compared with the conventional model, the rigidity is increased by 3 to 4 times. At the same time, because the inner ring or outer ring of the cross roller bearing has a two-part structure, the bearing clearance can be adjusted, and even if preload is applied, high-precision rotational movement can be obtained. http://www.zysbearing.com/precision-bearings/cross-roller-bearings.html

The slewing bearing is a large bearing that can withstand comprehensive loads, and can simultaneously withstand large axial and radial loads and overturning moments. Slewing ring bearings are generally equipped with mounting holes, internal gears or external gears, lubricating oil holes and sealing devices, which can make the host design compact, easy to guide, and easy to maintain. Slewing ring bearings have four-point contact ball bearings without gears, external gears and internal gears, double-row angular contact ball bearings, crossed cylindrical roller bearings, crossed tapered roller bearings and three-row cylindrical roller composite bearings. Series, four-point contact ball bearings have higher static load capacity, crossed cylindrical rollers have higher dynamic load capacity, and the pre-interference of crossed tapered roller bearings enable the bearings to have greater support rigidity and rotation accuracy. The three-row cylindrical roller combined bearing leads to the hei...

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.

First of all, the bearing classification of cranes will be classified according to the different parts used. The common parts used for bearings are: wheel group bearings, hook group bearings, pulley group bearings, drum group bearings, guide wheel groups, anti-roller groups, horizontal wheel groups, Supporting bearings such as eccentric wheels. Crane is a mechanical equipment with several lifting parts.  Crane bearing  is an indispensable part of crane operation. Lifting machinery equipment is an indispensable part of modern production, and bearings are an indispensable part of cranes. The bearing is an important basic component of lifting equipment, and its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the host. In hoisting machinery, bearings are high-precision products, which not only need comprehensive support from mathematics, physics and many other disciplines, but also require materials science, he...
