The bearing clearance is really important

Bearing clearance is the clearance (or interference) inside a single bearing or a system composed of several bearings. The clearance can be divided into axial clearance and radial clearance, which depends on the bearing type and measurement method.Why should the bearing clearance be adjusted?If the bearing clearance is too large or too small, the working life of the bearing and even the stability of the entire equipment operation will be reduced.The method of clearance adjustment is determined by the bearing type, which can generally be divided into non-adjustable clearance bearings and adjustable bearings.The non-adjustable clearance bearing means that the clearance of the bearing is determined after the bearing leaves the factory. The well-known deep groove ball bearings, self-aligning bearings, and cylindrical bearings all belong to this category. Adjustable clearance bearing means that the relative axial position of the bearing raceway can be moved to obtain the required clearance. In this category, there are tapered bearings, angular contact ball bearings and thrust bearings.For non-adjustable bearing clearance, the industry has corresponding standard values (CN, C3, C4, etc.), and specific clearance ranges can also be customized.The choice of the best working clearance is determined by the application conditions (load, speed, design parameters) and expected working conditions (maximum life, best stiffness, low heat generation, ease of maintenance, etc.).

Bearing steel market prices may continue to rise in May

2021-05-07 16:40:46

From January to March, domestic crude steel production of bearing steel increased by 23.97% year-on-year, and the output of bearing steel increased by 17.08% year-on-year. Looking back at the bearing steel market in April, the domestic bearing steel market prices continued to rise, driven by the rising cost of steel mills and the strengthening of the futures market in late April. Up to now, the average price of domestic bearing round steel 50mm (continuous casting) is 6255 yuan/ton, an increase of 155 yuan/ton from the end of March, an increase of 2.54% month-on-month. At present, downstream procurement costs have increased significantly compared with previous years. Excessive capital pressure has led to a slight slowdown in downstream procurement efforts, and the overall acceptance of high levels by terminal enterprises is low. With the announcement of the cancellation of export tax rebates for steel products, enterprises are more concerned about the subsequent impact on the export of bearing steel. However, in the recent stage, under the background of good fundamentals and high demand, under the stimulus of the continuous increase in the price of high-quality steel, it is expected that the market price of bearing steel in May may continue to rise.
