Using grease lubrication, should choose without impurities, prevent oxidation, rust, superior performance, such as extreme pressure grease. Grease filling quantity for bearings and bearing box - 30% of the volume 60%, unfavorable and overmuch. Needle roller bearing bear the mechanical load, so in the process of application and timely maintenance and maintenance to ensure the reliable operation of the mechanical equipment is a very important one annulus. New products using 100 work hours, check the bolt pre-tightening torque to stop working. If there is more than 10% of the bolt looseness, then work in 200 hours to check it again. Jiaxing needle bearing with stable after once every 500 hours to check; Bad working conditions to shorten the inspection intervals, as the case may be.
