ZYS precision bearing, ball bearings, roller bearings, bearing parts

The  electric  spindle is a kind of precision component with high speed and high rigidity. The  spindle  must be used strictly in accordance with the operating specifications, otherwise it will increase equipment failure and shorten equipment life. ZYS BEARING recommends the end user to follow the below rules during use: ⑴ Before starting the machine, first make sure that the spindle cooling system is working properly, and then turn on the electric spindle. It is strictly forbidden to use the spindle without cooling, so we must check whether the fan...

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...

I. Structural composition of  electric spindle The electric spindle is a new technology that combines the machine tool spindle and the spindle motor in the field of CNC machine tools in recent years. The main drive system of high-speed CNC machine tools eliminates the belt drive and gear drive. The main shaft of the machine tool is directly driven by the built-in motor, which shortens the length of the main drive chain of the machine tool to zero and realizes the "zero drive" of the machine tool. This type of transmission structure intergrating spindle motor and machine tool spindle, which makes the spindle components relatively independent from the drive system and overall structure of machine tool, so it can be made into a "spindle unit", commonly known as electric spindle or Motor Spindle. The electric spindle is a set of components, which includes the electric spindle itself and its accessories: electric spindle, frequency conversion device, oil mist lubric...
