Roller bearing Installation
All premature bearing failure, about 16% is due to improper installation or use proper installation techniques caused. For proper and efficient bearing installation, different applications may require the use of mechanical, hydraulic or heating method. Choose appropriate for your specific application installation methods to assemble the bearings will help extend bearing life and reduce premature failure of the bearing, and the resulting damage and costs incurred.
Small and medium-sized bearings typically use cold installation. Traditionally, a hammer and a length of the old pipe mounting bearings. This approach has the mounting force to pass by the rolling elements, will damage the bearing raceway. SKF installation tool only contact with the mounting surface of the bearing rings force to avoid damage to the bearings during installation.
Before installation, high temperature oil bath heated bearings are commonly used methods. However, this method may contaminate the bearing, resulting in premature bearing failure. Now, the induction heating method has become the most common bearing heating technology, since this method has a high degree of controllability, high efficiency and high safety. SKF Bearing induction heater for the development of established standards. SKF Bearing induction heater has many features, when heated to prevent bearing damage.
SKF pioneered the hydraulic technology for bearing installation, such as SKF oil injection method (SKF Oil Injection Method) and SKF hydraulic drive method (SKF Drive-up Method). These methods help simplify bearing arrangement, to facilitate proper installation. SKF has developed a full range of hydraulic tools and equipment series, in order to apply these hydraulic technology.
Initial lubrication of bearings
Slewing bearing are pre-lubricated, the installation does not require additional lubrication. However, the use of all applications open bearings, these bearings must be lubricated after installation. For your application choose the right bearing grease is to maximize bearing life is a critical step. SKF offers thirteen different grades of bearing grease specially developed by the SKF, for most bearing applications
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.
