Cleaning, Installation and Dismantling of Rolling Bearings
Introduction
Rolling bearings are a key component of a range of mechanical engineering components and assemblies. The rolling bearing is designed to withstand the rigors of high speed rotation, while also providing maximum efficiency with minimal friction. Properly installed and maintained rolling bearings can ensure long-term smooth running, reliable performance and safety as well as increasing machine productivity. In order to ensure that the rolling bearing can fully play its role, the cleaning, installation and dismantling should be done carefully and methodically.
Cleaning
Regular cleaning of rolling bearings can maintain its performance. Generally, it is necessary to clean the bearing before installation. It is recommend using a brush with clean kerosene or gasoline to clean the bearing cavity proper, cage and roller. If the bearing is rusty, we should remove the rust before it starts to deteriorate the bearing. A light trace of oil can be applied to the bearing to prevent rusting during storage.
Installation
Rolling bearings should be handled properly so as not to damage the bearing and related parts. The installation process requires special tools that fit precisely over the bearings, helping to ensure correct alignment and axial pre-load. Incorrect installation of the bearing can lead to premature bearing failure and machine breakdown.
Its important to keep the bearing and its related components clean to avoid contamination. Rolling bearings should be lubricated before installation and afterwards, too. The exact lubricant can often depend on the application, but it should be of a high quality and free from impurities.
Dismantling
When dismantling rolling bearings, proper tools as well as the correct technique should be used to avoid damage. Generally, the bearing should be released from the component slowly, with even pressure on both sides. Outward pressure on both sides of the bearing should be applied rather than a single strong force. It is important to take great care during dismantling the bearing so that it does not become damaged and corrupted in any way.
Conclusion
In conclusion, cleaning, installation and dismantling of rolling bearings is a very important procedure to ensure proper performance, longevity and safety of the components as well as increasing machine productivity. As such, it is essential that it is done correctly
