Extending the Bearing Life Cycle. Mechanical tools. Heating tools. Hydraulic tools. Basic condition monitoring. Automatic lubrication. Manual lubrication. Lubrication management tools. Help your bearing achieve its maximum service life. Every bearing has a pre-calculated service life. However, research has shown that, for various reasons, not every bearing achieves it. These stages are mounting, lubrication, alignment, basic condition monitoring and dismounting.

The stages in a bearing life cycle are extremely important for achieving the maximum service life of the bearing. Includes mechanical fitting tools, induction heaters and hydraulic equipment. Individual applications may require mechanical, heat or hydraulic mounting methods for correct and efficient bearing mounting. Includes shaft and belt alignment tools and machinery shims.

After the bearing has been mounted in an application such as a motor connected to a pump, the application should be aligned. If the application is not properly aligned, the misalignment can cause the bearing to suffer additional load, friction and vibration. Furthermore, increased vibration and friction can significantly increase energy consumption and the risk of premature failures.

Includes bearing greases, manual and automatic lubricators and lubrication accessories. During operation, the bearing will require periodic relubrication. The right quantity of the right grease applied at the right intervals is essential to achieving optimum bearing performance and maximum service life.

Using manual relubrication methods is common practice; however, continuous relubrication offers many advantages. Continuous relubrication can be performed by using automatic lubricators, which provide a more consistent, correct and contamination-free grease supply. Includes temperature, sound, visual inspection, speed, electrical discharge and vibration measuring instruments. During operation, it is important to regularly inspect the condition of the bearing by performing basic condition monitoring measurements.

These regular inspections will allow the detection of potential problems and help to prevent unexpected machine stops. Includes pullers, both mechanical and hydraulic, induction heaters and hydraulic equipment. At some point, the bearing will reach the end of its service life and will have to be replaced. Although the bearing may not be used again, it is extremely important to dismount it correctly so that the service life of the replacement bearing is not compromised.

Firstly, the use of proper dismounting methods tools will help prevent damage to other machine components, such as the shaft and housing, which are often re-used.

Secondly, incorrect dismounting techniques can be hazardous to maintenance personnel. On the Internet, SKF can be found at www. SKF Maintenance Products can be found at www. Poor fitting. Individual installations may require mechanical, hydraulic or heat application methods for correct and efficient mounting or dismounting. SKF offers a complete range of tools and equipment to make these tasks easier, quicker and more cost effective, backed up by a wealth of service engineering know-how.

Professional fitting, using specialised tools and techniques, is another positive step towards achieving maximum machine uptime. Poor lubrication. Inevitably, any bearing deprived of proper lubrication will fail long before its normal service life. Because bearings are usually the least accessible components of machinery, neglected lubrication frequently compounds the problem.

Wherever manual maintenance is not feasible, fully automatic lubrication systems can be specified by SKF for optimum lubrication. Effective lubrication and using only recommended SKF greases, tools and techniques helps to significantly reduce downtime. A bearing is a precision component that will not operate efficiently unless both. SKF has an unrivalled bearing manufacturing and design capability and can tailor sealing solutions for the most arduous operating environments.

Whenever machines are overloaded, incorrectly serviced or neglected,. The SKF range includes hand-held instruments, hard-wired systems and data management software for periodic or continuous monitoring of key operating parameters.

SKF Hydraulic Pumps. SKF Screw Injectors and SKF Oil Injector series. SKF Pressure Gauges. Mounting and dismounting. Mounting bearings in a cold condition. Small and medium size bearings are generally cold mounted. Traditionally, the bearing is mounted using a hammer and a length of old pipe. This practice can cause forces to be transmitted through the rolling elements, resulting in damage to the raceways. Mounting bearings using heat. Oil baths are often used for heating bearings prior to mounting.

However, this method can contaminate the bearing, resulting in premature bearing failure. Today, induction heating is the most common technique for heating bearings since it allows a high degree of controllability, efficiency and safety. SKF has set the standards for the development of induction heaters for bearing applications. SKF bearing induction heaters are equipped with many features, which help prevent bearing damage during heating.

Mounting bearings using hydraulic techniques. These techniques have helped to simplify bearing arrangements and facilitate correct and easy mounting. SKF has also developed a comprehensive range of tools and equipment to put these hydraulic techniques into effect. Mechanical tools — Introduction. Bearings are sometimes dismounted to maintain or replace other components of the machine.

These bearings are often re-used. Selecting the correct dismounting methods and tools is then essential in reducing the risk of personal injuries and reducing the risk of damaging the bearing, thus allowing it to be used again. Individual applications may require mechanical, heat or hydraulic dismounting methods and tools to allow safe, correct and efficient bearing dismounting.

Mechanical dismounting. Choosing the right puller for the job is critical. The puller type, and its maximum withdrawal capacity are crucial for completing any dismounting job safely and easily. This breakage can damage the bearing or shaft and can cause personal injury. In general, it is recommended to use a three-arm puller rather than a two-arm puller as the three-arm puller is more stable.

Whenever possible, apply the withdrawal force to the ring with the interference fit. SKF offers a complete range of easy-to-use mechanical, hydraulic and hydraulically- assisted bearing pullers for use in many bearing applications. Dismounting using heat. The inner rings of cylindrical roller bearings generally have a tight interference fit, which requires high forces to dismount.

In such cases, using a puller can cause damage to the shaft and ring, which can be hazardous to the operator. Using heating equipment facilitates easy and quick dismounting while reducing the risk of damage to the ring and shaft. SKF offers a range of heating equipment, which includes aluminium heating rings as well as adjustable and fixed induction heaters, for dismounting cylindrical roller bearing inner rings. Dismounting bearings using hydraulic techniques.

The SKF hydraulic techniques are often the preferred method for dismounting larger bearings as well as other components. These techniques, which employ hydraulic pumps, nuts and oil injectors, allow the application of substantial forces to dismount bearings or other components.
