Smearing anti-rust oil on bearing to prevent rust

Bearing corrosion is commonly in operation process. Following are some method to prevent bearing corrosion.1. Immersion method.Some small bearings could be immersed in anti-rust grease. Thickness of oil film can be achieved by controlling the temperature or viscosity of the anti-rust grease. Making the bearing surface adhere to a layer of anti-rust grease to achieve anti-rust effect.2. Brush coating methodSpreading on the bearing surface evenly, do not pile up, but also pay attention to prevent l…

The Major Performance Factors of Bearing

1. HardnessHardness is one of the important parameters of bearing quality, which has a direct impact on contact fatigue strength, wear resistance and elastic limit. The hardness of the bearing in use should generally reach HRC61 ~ 65, so the bearing can obtain higher contact fatigue strength and wear resistance.2. Anti-corrosion PerformanceIn order to prevent bearing parts and finished products from being corroded and rusted during processing and storage, the bearings should have good anti-rust p…

Sound of Normal operating bearings

Sound of Normal operating bearings1. Low buzz sound when bearings under good operating state. Otherwise, it will sound sharp hissing, squeaking, or other irregular sound. Improper lubrication may cause this situation. Plus, improper bearing clearance can also make the same.2. Dent on the outer ring race may lead to the vibration and make the smooth and clear sound.3. It shows the rolling piece might be damaged when intermittent noise occurs. When the damaged surface being crushed, it will make th…

The reason why the bearing temperature is too high

The reason why the bearing temperature is too high1. Poor lubricationLubrication has an important influence on the service life of the bearing, friction, wear and vibration, etc. Good lubrication is a necessary condition to ensure the normal operation of the bearing. About 40% of bearing damage is related to poor bearing lubrication.The role of lubrication for bearings mainly includes:1) Prevent metal corrosion2) Exclude foreign materials, play a sealing role3) Discharge friction heat…
