Metal linear bearing and linear bearing plastic preventive maintenance and how to do?

With the improvement of the machining precision of linear bearing, the use of linear bearing is now in the precision equipment and special mechanical line is very common, such as automobiles, robots and digital three coordinate measuring device, linear bearing this writing can play a important role in equipment, so a linear bearing is more and more people's concern. Linear bearing in the operation of the process in order to better and maintain its performance, is the need to align for maintenance. The linear bearing maintenance is divided into linear bearing metal and plastic linear bearing two kinds. Metal linear bearing maintenance need to be aware of is the lubrication and friction two main, its operation is in the interior of the linear bearing anticorrosive oil injection parts, in the air drying after adding grease. Axis lubrication can from for tubing or oil hole on the outer bearing for oil. Because the sealing ring will scrape the inside of the lubricating oil, so oil lubrication can not apply without hole with seals bearing. For the plastic linear bearing maintenance maintenance, mainly due to the inside of the plastic linear bearing sliding film with self-lubricating plastic, so in the process of using don't need the extra oil supply and maintenance. And plastic linear bearing clearance groove, so the bearings or shaft filled with dust above also don't need to be maintained, dust automatically in the process of movement by the chip groove excluded, and plastic linear bearing can also in use process to clean. So straight axis relative to metal, plastic linear bearing more the need for maintenance.
