As an important component in mechanical equipment, bearings are not only used in the machinery manufacturing industry, but also in other industries. <br>1. Machine tool bearings <br>As the basic supporting parts of the machine tool, the performance of the machine tool bearing directly affects the machine tool's speed, rotation accuracy, rigidity, anti-vibration cutting performance, noise, temperature rise and thermal deformation, etc. Surface quality, etc. Therefore, high-performance machine tools must be equipped with high-performance bearings. Especially high-speed precision CNC machine tool bearings. The precision of rolling bearings is generally divided into five levels: P0, P6, P5, P4, and P2. The precision of bearings used on the spindles of precision machine tools should be P5 or above. For spindle support, P4 and above super-precision bearings are required. <br>Machine tool spindle bearings generally include six types of structures: deep groove ball bearings, angular contact ball bearings, cylindrical roller bearings, two-way thrust angular contact ball bearings, tapered roller bearings and thrust bearings. <br>2. Printing machinery bearings<br>Printing machine bearings are used for the main cylinders of sheet-fed and web-fed printing presses. Due to the complexity of application requirements, only a small part of printing machinery bearings can be standardized. Therefore, printing machine bearings include many models and sizes. In addition to the typical multi-row, high-precision cylindrical roller bearings NN, NNU, N4N, N4U, it also includes floating bearing units, locating bearing units, polygon bearings, linear and rotary bearing combination units and tapered rollers with or without eccentric rings Sub-bearing unit. There are two types of bearing: sealed and not sealed. The journals at both ends of the drum can be cylindrical or conical. <br>3. Textile machinery bearings <br>During spinning or weaving, finishing or processing, modern textile machinery is highly automated and requires uninterrupted operation under high output and trouble-free conditions. The so-called "good bearing" means low friction, high accuracy, zero clearance, easy installation, less maintenance, long life, low rang and high reliability. These leather belt wheels are easy to lubricate and have a low moment of inertia. Therefore, they can quickly reach the working speed. In addition, these belt tensioners can achieve continuous operation in up to 600 alternating rotations per minute with low energy consumption. These features make it possible to obtain uniform and high-quality fabrics while greatly increasing the output of the machine while significantly reducing costs. <br>4. Bearing <br>food production in the food and packaging industry must be both economical and efficient. It is usually an automated production process, and extreme operating conditions often occur. This requires a high degree of security and reliability. The design suitable for continuously working high-quality machine components is an essential element here. Robust, corrosion-resistant bearings, effective sealing and lifetime lubrication under most operating conditions, suitable for reliable uninterrupted operation. <br>5. Woodworking machinery bearings <br>In many cases, deep groove ball bearings can well meet the high-speed and relatively low-load working conditions of the bearing arrangement in woodworking ox head planers. For very high speeds, spindle bearings are usually used.
