Tools for working with bearings and devices

Keep safe, fast and efficient tools for working with bearings and devices

Maintenance and service technicians in their work need special tools and devices for safe, quick and efficient assembly, dismantling and supervision of the state of bearings.

Tools are divided into three groups:

Tools for mounting bearings:

16% of premature bearing failure is the result of improper and unsafe assembly of bearing. Proper installation of bearing such as a substantial impact on its lifecycle. With proper installation of bearing significantly extended for the life of which is a positive impact on maintenance costs.

Incorrect installation can cause damages to the bearing and an early failure.

Incorrect adaption for the assembly can cause excessive wear and the early damage.

To avoid the above mentioned problems it is very important to select appropriate tools and proper manner bearing assembly.

There are three methods of mounting bearings:

Mechanical Installation

Mechanical or cold mounting is suitable for small to medium-sized bearings. Use appropriate tools to prevent damage to bearings, other components and not the least injury to persons.

Installation using heating

Installation by using heating means based on the induction and it is used in medium and large bearings. By increasing the size of bearings also increase the force required for assembly of the bearing. Due to the size of force are larger bearings very difficult to push the shaft or casing. Pre-heating of the bearing or casing before installation is extremely simplified. In assembly with heated bearing to a temperature that is 80 to 90 ° C above the temperature of the shaft, which mounts bearings.

Installation using hydraulic

JIs the most widespread method of assembling large bearings. In this method, there is minimal risk of damage bearing, shaft and other components. Despite the size and weight bearing requires very little effort which is required for installation, while providing a safe working environment without significant risk injury to employees.

Principle of the hydraulic assembly technique consists of injecting the thin layer of oil between the bearings and shaft, which greatly reduces friction and allows the bearing assembly with the minimum necessary force.

The method is not only useful for bearings, but also in other mechanical components, which the classic method of assembly would have been rather problematic.

Tools for dismantling bearings

At the dismantling of bearings should be careful not to damage the other components (shafts, bearing cases ...), because damage could result in reduced efficiency of machine, Device and reduces its lifetime.

These bearings then will be re-installed to the drive, so you will need to use appropriate tools and methods for dismantling that ensure that the bearing remains intact and suitable for continued smooth operation.

There are three methods of dismantling:

Mechanical removal

Mechanical removal is suitable for small to medium-sized bearings. Use of appropriate tools to prevent damages to bearings, other components and not the least injury to persons.

There are several types of downloads, allowing the dismantling of all types of bearings under all conditions:

• mechanical Downloads
• hydraulic Downloads
• Downloads for blind casings

Dismantling with the heat

Dismantling with the heat is mainly suitable for bearings with close fitting. The use of mechanical downloads could damage the shaft or bearing rings in this case, it requires more power. By using special heaters there are significantly easier to dismantle and reduce the chance of damage to components and body injury.

The heaters for dismantling are basically divided into:

• heated rings
• induction heaters

Dismantling by Oil injectio

JIt is a common choice for major dismantling of bearings and other components. Allows disassembly with a substantially lower power and significantly reduce of possibility of damaging bearing, shaft and grounding.

The basic principle of the method is injecting oil down the certain viscosity between two surfaces, while between them the pressure generated oil film and differentiate them. This method can reduce the necessary force to dismantle the casing up to 90%.

Tools and devices for the control of the situation

To ensure long lifetime of the bearing is important to determine the status of devices and bearings throughout the lifecycle of the bearing

Checking the Status (predictive maintenance) is monitoring the situation and bearing installations during drive operation. In this way, it can significantly reduce production delays and lower total cost of maintenance and operation during the production.

SKF has developed a wide range of measuring instruments that measure and analyze critical parameters that significantly affect the operation of bearings and equipment:

• Temperature
• Speed
• Speed
• Noise
• Oil level

Supervision of the status provides the lowest maintenance costs, unlike the methods of work to failure and preventive maintenance, allowing replacement of parts just before their failure.
