The characteristics and the protection of F-3167-B Timken NSK bearing rolling mi
A rolling mill bearing characteristics, NSK:
1, roller and raceway contact or line contact repair line, radial load capacity, suitable for receiving heavy load and shock load. The friction coefficient is small, suitable for high-speed, the speed limit is close to the deep groove ball bearing NSK.
2, can axially move, can adapt to the change or due to thermal expansion device error caused by the relative position of the shaft and the housing, can be free end bearing application.
3, the shaft or the seat hole machining requirements higher, NSK bearing device outer axis relative deviation should be strictly controlled, so as to avoid the formation of contact stress concentration.
4, the inner or outer ring can be respectively, convenient device and open.
5, adhere to high speed steel stamping, NSK bearings or request operation NSK bearing imports stable, with solid cage. According to the site and user requirements, also can design and supply with glass fiber reinforced plastic cage.
Two, the mill NSK bearing protection, maintenance and exception handling:
1, in order to maintain the function of time NSK bearing the original superior to form, to protect, repair, in order to avoid chaos in the bud, ensure the operation of solid, productive, economic progress.
2, to protect the best response operating standards mechanical operation of the premise, on schedule. Including the custody operation form, supplement or change the smooth agent, to open the reflection.
3, as a matter of maintenance in operation, the torsional sound, NSK bearing vibration, temperature, smooth agent form etc..
