Service and Repair

In many cases, a studied and precise modification of a standard bearing makes it possible to meet the needs of our customers cost-effectively. Changing clearances is probably the most common modification, but we also regularly incorporate some elements made with custom materials that are indicated to withstand the most demanding working conditions.

These modifications can also be demanded to improve and facilitate the maintenance of the equipment, and to reduce its downtime.

Types of bearing modifications

• Special ball bearings and cylindrical rollers manufacturing.
• Manufacture of spherical and spherical plain rollers.
• Reconditioning of ball and cylindrical roller bearings.
• Remachining of bearing races to change clearances (Ex. C3 to C4)

• Bearing disassembly to replace steel or plastic retainers with bronze or phenolic ones.
• Disassembly of bearings to replace balls for ceramic balls.
• Add W33 or W26 to ball or roller bearings.
• Add tapered bore to ball or roller bearings.
• Add spherical OD and self-aligning rings to the outside diameter of bearings.
• Add localized holes for shear pins in the outside diameter of bearings.
• Manufacture of spacers for tapered ball and roller bearings.
• Preloaded angular contact ball bearings and radial ball bearings.
• Adding rings in grooves and in ball, spherical, cylindrical and tapered roller bearings.
• Manufacture of 5L and N5L NDH style bearings.
• Adding V-grooves to the outside diameter of bearings.

The retrofit of mechanical systems basically consists of updating or modernizing mechanical parts that have become outdated for current production requirements and that with their improvement or replacement we can renew and update the functionalities and improve the capacities of the production system.

Frequently, the need to update a mechanical system is motivated by the obsolescence of spare parts, by the need to add new functionalities and capacities to the production system, or by being able to make it compatible with new modules in a production line.

The high costs that new machinery would entail mean that more and more production plants are considering, once the amortization period of their products is over, retrofitting them, also adding features, applications and better security systems, adapting them to new regulations.

Obviously, the retrofit of industrial machines or heavy machinery is not simple and requires means, infrastructures, knowledge and experience that are not available to any company.

All rotating machinery has a vibration level that can be considered normal to its operation. When this level rises and becomes excessive, it is usually a sign that something is wrong.

Vibration analysis is one of the most widely used techniques both to assess the possible failures of a bearing or a mechanical part that has already shown anomalies, as well as to detect minor errors in time that could lead to more extensive damage. That is, it is used for both preventive and corrective maintenance.

The analysis of the state of the bearings includes comparisons of the vibration spectrum with the ideal spectrum established for said bearing by the manufacturer, this allows to establish where the failure or wear is most likely to be occurring.

Vibration analysis can accurately diagnose problems of:

• Imbalance
• Misalignment
• Clearances
• Rods
• Bent axles
• Eccentric pulleys
• Bearings
• Gears
• Electrical faults

The main source of infrared radiation is heat or thermal radiation. Any object that has a temperature above absolute zero emits radiation in the infrared zone.

A large part of the problems that arise in mechanical industrial environments are preceded by changes in temperature that can be detected by heat radiation capture systems. The use of thermographic inspections within the predictive maintenance programs in heavy industry makes it possible to locate possible errors in a non-destructive way and thus prevent more complex breakdowns that could lead to production paralysis.

The analysis of lubricants is a recommended task for the predictive maintenance of industrial production systems, a necessary activity to check the state of wear of the internal mechanical components of the machines, and more specifically, that of those elements that rub against each other such as bearings.

Boroscopic inspections are visual inspections in places inaccessible to direct visual inspection. To carry it out, we need optical equipment that allows it to move into hard-to-reach places. The borescope is the tool that is used and that gives its name to this type of inspection. It is a long and thin device in the form of a flexible rod that ends in an ultra-angular camera and is prepared to capture optimal images in low light conditions and transmits the images to an external monitor for them to be visualized and technically interpreted by qualified engineers.

ABS, Atlantic Bearing is pleased to inform you that it has incorporated within its Engineering Service platform a real time in field torque measurement Service. This service consists of real-time measurement of torque and power in mechanical power transmission systems with the latest portable technology. Strain gauges can be easily installed safely on the application, Battery bank supplies power and through the deformation of the gauges a wireless transmitter allows the system to collect precise Data. Mathematical algorithms process the information and displays tables and graphs for ease of interpretation.
