In principle, all NSK bearings prior to installation should be kept in their original packaging. They need to stay in a clean, moisture free, relatively constant temperature in the environment. Rolling NSK Bearings should stay away from dust, water and corrosive chemicals. Shaking and vibration may forever destroy the mechanical properties of NSK bearings, so the handling and storage process must avoid vibrationBasically, all levels of NSK bearings have to be saved, Tapered bearing some heavier NSK Bearings long vertically, it may be deformed due to its own weight.
Clean the tapered roller bearing is very important. NSK Bearing ring rolling surface and the rolling elements of the surface roughness is typically 1/10 μm, such a smooth surface of pollutants are very sensitive to damage. A lubricating layer between the rotating surface is generally 0.2 ~ 1 μm, a particle size larger than the lubricant-type impurity will be rolled over the rolling element bearings in the NSK partial pressure produced in steel, fatigue will eventually cause permanent. In addition to this, the external environment in the dust particle size of up to 10 μm, NSK bearings will also cause damage. Therefore, clean dust-free environment for NSK Bearings storage and installation is critical.
Backing bearings are particularly thick outer ring of the rolling bearing, when used to form a group to be mounted on the shaft of a stationary support rollers. Pressure on the work roll through the intermediate roller and the support roller is passed to the system to the rack through the saddle. Generally used for multi-roll cold rolling mill equipment can also be used for other occasions, such as straightening machine.
