high temperature bearings-manufacture,factory,supplier from China

Rolling bearings are precision components, and their use must be carried out with corresponding care. No matter how high performance bearings are used, if they are not used properly, the expected high performance will not be obtained. Notes on the use of bearings are as follows.1、Keep the bearing and its surrounding environment cleanEven if the tiny dust invisible to the naked eye enters the bearing, it will increase the wear, vibration and noise of the bearing.

New energy passenger car transmission bearings include deep groove ball bearings, angular contact bearings, four-point contact bearings, tapered roller bearings,  cylindrical roller bearings.Working characteristics of new energy vehicle bearings: high speed, high load, low friction, low noise, long life.In order to improve the service life of new energy vehicle gearbox bearings, in addition to using computer simulation software for simulation design on the bearing structure, low-friction optimization design is carried out on the bearing raceway, microscopic modification, and early failure

Shandong NYZ Bearing Manufacturing Co., Ltd. also holds Shandong Bearing Machinery Technology Co., LTD. the company's main business and production, bearings and bearing accessories. The main model of the manufacturer is OEM/ODM, strategic cooperation bearing field well-known brands at home and abroad. Products are widely used in metallurgy, wind power, s petroleum, electrical machinery, chemical industry, construction machinery, mining equipment, laser printers, automobiles, small high-speed equipment and other industries.

Rolling bearings are usually composed of rings, rolling elements and cages.Rolling bearing classification1 Rolling bearing classificationRolling bearings according to the direction of the load or nominal contact angle, divided into: centripetal bearings and thrust bearings.Radial bearing one is mainly used to bear radial load rolling bearing, the nominal contact angle of 0 ° ≤ a ≤ 45 °.Thrust bearing one one is mainly used to bear axial load rolling bearing, the nominal contact angle of 45 ° < a ≤ 90 °.Motion cover2 Various bearing characteristicsDeep groove ball bearingsDeep groove ball be

In recent years, Axis Technology has successively developed 4.XMW, 5.XMW, and 6.XMW wind power gearbox bearings around the field of wind power gearbox bearings. The 8 MW level wind power gearbox bearings rolled off the assembly line this time, firstly, the specifications have been upgraded, which is more suitable for the current development trend of large-scale wind turbines; secondly, a full range of supply has been realized, and the product types cover all semi-direct drive and double-fed models.

The inner and outer rings of tapered roller bearings have tapered raceways, and the rolling elements are also tapered, which is a separable bearing. The main structural forms are divided according to the number of rolling rows: single-row tapered roller bearings, double-row tapered roller bearings, and four-row tapered roller bearings.According to the size of the contact angle:Small cone angle (9°<a≤25°)Large cone angle (> 25°) points.The axial load-carrying capacity of tapered roller bearings depends on the contact angle a, that is, the raceway angle of the outer ring.

Fitting of bearingsI. Choice of fitThe inner diameter and outer diameter of rolling bearings are manufactured according to standard tolerances. The tightness of the fit between the inner ring and the shaft and between the outer ring and the seat hole can only be achieved by controlling the tolerance of the journal and the tolerance of the seat hole.

1、Deep groove ball bearings can be used in gearboxes, instruments, motors, household appliances, internal combustion engines, traffic vehicles, agricultural machinery, construction machinery, engineering machinery, etc.2、Spherical ball bearings are suitable for bearing heavy load and impact load, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, rolling mills, mines, petroleum, paper, cement, sugar and other industries and general machinery, etc.3、Combined needle roller bearing is a bearing unit combined by radial needle roller bearing and thrust bearing parts, its

The correct mounting of spherical roller bearing bearing affects the accuracy, life and performance. Therefore, the design and assembly department for the installation of thrust spherical roller bearings should be fully studied. Hope to be installed in accordance with the operating standards.

In order to prevent loose sleeves or rollers from falling off during the handling and installation of cylindrical roller bearings, locking points or locking claws [1], are often designed around the pockets of the cage to ensure that the cage, rollers, and rings are not locked after the bearing is assembled. External forces are inseparable [2]. There are many pockets in the cage, and there are locking claws on both sides of each pocket. The symmetry and locking amount of the locking claws directly affect the performance of the bearing.
