Overview: From January to March 2023, the domestic production of bearing steel crude steel decreased by 0.69% year-on-year, and the output of bearing steel decreased by 2.63% year-on-year. Looking back at the bearing steel market in April, the overall trend was volatile and downward. The downstream demand started less than expected, and the mentality of businesses was frustrated. Up to now, the average price of domestic bearing round steel 50mm (continuous casting) is 5394 yuan/ton, which is 84 yuan/ton lower than that at the end of March, and the month-on-month decrease is 1.56%.

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.

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.

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.

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

Since the beginning of this year, in the face of the severe and complex international environment and the arduous and arduous domestic reform, development, and stability tasks, under the strong leadership of the Party Central Committee with Comrade Xi Jinping at the core, all regions and departments have earnestly implemented the decisions and deployments of the Party Central Committee, and insisted on the word "stability".

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.

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

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

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.
