Briefly describe the characteristics and applications of rolling mill bearings Japan NSK bearings

1. Rolling mill bearings Japan NSK bearing features:

　　1. The roller and the raceway are in line contact or under-line contact. The radial load can be large, and it is suitable for accepting heavy loads and impact loads. The friction coefficient is small, suitable for high speed, and the limit speed is close to the deep groove ball bearing.

　　2. It can be moved axially, can adapt to the change of the relative position between the shaft and the housing caused by thermal expansion or device error, and can be used for free end support.

　　3. The processing requirements for the shaft or the seat hole are relatively high. The relative deflection of the outer ring axis after the NSK bearing device should be strictly controlled to avoid contact stress concentration.

　　4. The inner ring or outer ring can be separated for easy installation and disassembly.

　　5. Steel plate stamping holders, for high-speed bearings or imported bearings that require stable operation, use solid holders. According to the application site and user requirements, the holding frame made of glass fiber reinforced plastic can also be designed and supplied.

　　 2. The protection, maintenance and abnormal handling of rolling mill bearings NSK bearings:

　　1. In order to maintain the original function of the bearing in a superior form for a long time, it must be protected, overhauled, and prevented from being disrupted in the first place, ensuring the reliability of operation, and improving productivity and economy.

　　2. The protection should best respond to the homework norms of the mechanical operation premise and be carried out on schedule. The content includes the introspection of taking care of the operation mode, adding or changing the smoothing agent, and dismantling on time.

　　3. As the maintenance items during operation, there are the torsion sound, vibration, temperature, and the form of the smoothing agent of the Japanese NSK bearing.
