Principle of Bearing Replacement and Grease Filling

1. Commonly, bearing inner space should not be fulfilled with grease. Usually, it would be better to install 1/2 or 3/4 in the whole space bearing cavity.2. Filling with 2/3 to 3/4 of the inner cavity space for axial bearing ;3. Filling with 1/2 (upper) and 3/4 (lower)space for radial installed bearing;4. In easily-polluted environment, fulfill with grease in the entire space for low speed or medium speed bearings.For high-speed bearings, put the bearings in high-quality lubricating oil before l…


Causes of Needle Roller Bearing Failure

Generally speaking, 33.3% of needle roller bearings are damaged due to fatigue damage, 33.3% of needle roller bearings are due to poor lubrication, and 33.3% are due to pollutants entering the bearing or improper equipment disposal. Dust cleans the bearing and the surrounding environment. The fine dust invisible to the naked eye is a powerful killer of the bearing, which can increase the wear, vibration and noise of the bearing. Stamping forms strong stamping when using equipment, which is very…


Recent bearing steel market price tendency

From Jan. to Sep., the output of domestic crude steel bearing increased by 3.68% year-on-year, and the output of bearing steel fell 0.85% year-on-year. Looking back at the bearing steel market in October, the overall transaction performance was acceptable, and the market price is still rising slightly. So far, the average price of domestic bearing round steel 50mm (continuous casting) is 4963 RMB/Ton, an increase of 10 RMB/Ton from the end of September, A month-on-month increase of 0.2%.

Rolling Bearing Precision Level Selection

Rolling bearing precision level selectionThe precision level of rolling bearings should be selected in accordance with the mechanical accuracy. To improve the rotation accuracy of the machine and reduce vibration and noise, it should not only rely on increasing the bearing tolerance level. It is necessary to pay attention to the manufacturing accuracy, manufacturing quality and assembly quality of the matching parts. The bearing price double raised according to different bearing precision levels,…
