  • What is the working principle of the bearing oil seal?

    What is the working principle of the bearing oil seal?

    1. In the free state, the inner diameter of the oil seal lip is smaller than the shaft diameter and has a certain amount of interference.2. After installation, the interference pressure of the oil seal edge and the contraction force of the self-tightening spring will produce a certain radial pressur... read more

  • How to extend bearing performance?

    How to extend bearing performance?

    1. To improve bearing performance, reasonable adjustment is very important.During assembly or installation, if the internal clearance of the bearing is too large or too small, or in some cases, the preload is too high, which may cause early damage and shorten the bearing life. In addition to causing... read more

    How to extend bearing life?

    1. Lubrication is the keyChoose a suitable lubrication system and high-quality lubricants.The lubricating oil film separates the oil film surfaces that are in contact with each other due to load, and provides the necessary protection against corrosion and wear. Therefore, for all rotating or recipro... read more
