FAG in industry: typical applications
FAG bearings are found in equipment for mining, steel, paper, cement, energy and agro-industry. Their robust design makes them suitable for heavy loads, high speeds and contaminated environments. In Argentina, many maintenance managers choose them for their reliability under demanding conditions.
In mining, for example, spherical roller bearings withstand misalignments and impact loads in conveyor belts and mills. In the paper industry, cylindrical and angular contact rollers work in press rolls and dryers. Each application has a specific FAG bearing.
The key is to correctly identify the load: radial, axial or combined load, speed, temperature and presence of contaminants. With that data, you can choose from the broad FAG range we sell at MR Accesorios Industriales.
How to select the correct FAG bearing
Selection starts with the bearing type. A deep groove ball bearing is versatile for moderate radial and axial loads; a tapered roller withstands combined loads and adjusts precisely; a spherical roller tolerates misalignments; and a cylindrical roller is ideal for high radial loads at speed.
In addition to the type, you must define the dimensional series and internal clearance. For example, the C3 suffix indicates greater radial clearance, useful when there is thermal expansion or interference fits. FAG offers variants with seals, special cages and treatments for high temperatures.
At MR we help you choose: you send us the size, estimated load and working conditions, and we quote the appropriate FAG bearing. We also work with adapter and withdrawal sleeves for mounting on plain shafts.
Mounting FAG bearings: good practices
Incorrect mounting is a frequent cause of premature failure. For FAG bearings, it is recommended to heat the bearing (max. 120 °C) for interference fits, or use a press if the fit is light. Never strike directly on the rings or rolling elements.
Adapter sleeves, such as those we sell, allow mounting bearings with a tapered bore on cylindrical shafts. They are tightened with a nut and wrench, controlling the reduction of radial clearance. For dismounting, withdrawal sleeves facilitate removal without damaging the bearing.
Cleanliness is essential: the shaft and housing must be free of burrs and dirt. Use suitable tools and follow the manufacturer's instructions. Good mounting extends service life and prevents unplanned stoppages.
Preventive maintenance for FAG bearings
Preventive maintenance includes correct lubrication, vibration and temperature monitoring, and seal inspection. The grease or oil must be compatible with the bearing and the application. Excess grease is also harmful: it generates heat and increases friction.
Monitoring condition with vibration analysis allows detecting incipient failures, such as flaking or wear. A temperature increase may indicate insufficient lubrication or excessive load. Recording this data helps plan interventions.
At MR we advise you on lubricants and maintenance accessories. If you need to replace a FAG bearing, we quote the exact code or indicate the compatible alternative, always with the brand's quality.
FAG bearings by type: examples of codes
Within the FAG line, there are references for every need. For example, in spherical roller bearings, codes such as 20222-MB or 20240-MB are used in applications with heavy loads and misalignment. In cylindrical rollers, SL182226 or SL183018 are robust options for high radial loads.
In tapered rollers, 33115 or 32915 are common in gearboxes and wheels. For mounting with sleeves, AH211 or AH308 facilitate fixing. And in special bearings, ZM85 or ZM70 cover specific applications.
These are just examples: the FAG range we sell includes thousands of references. If you have the code of a bearing to replace, send it to us and we will quote it instantly.
FAG and other brands: when each is convenient
FAG is a reference brand in high-demand bearings. However, at MR we also work with other brands to offer alternatives according to the application and budget. The choice depends on the criticality of the equipment and the working conditions.
If the original bearing is FAG, the ideal is to replace it with the same one to maintain performance. In less demanding applications, an equivalent alternative can be evaluated. Our technical team advises you without obligation.
The important thing is not to improvise: an inadequate bearing can fail early and generate higher costs. Consult us and we will help you decide with technical criteria.
Where to buy FAG bearings in Argentina
At MR Accesorios Industriales, based in Buenos Aires, Argentina, we sell FAG bearings throughout the country. We work with maintenance managers and industrial buyers looking for quality and advice.
To get a quote, send us via WhatsApp or email the bearing code, the size or a photo of the part. We respond promptly with the proposal. We also help you identify the bearing if you do not have the code.
Do not hesitate to consult us about sleeves, mounting tools or lubrication. Our goal is to keep your equipment running smoothly.
Frequently asked questions
What does the C3 suffix mean in a FAG bearing?
The C3 suffix indicates greater internal clearance than normal. It is used when there is thermal expansion, interference fits or loads requiring greater clearance. It is important to verify the original equipment specification.
How is a FAG bearing mounted with an adapter sleeve?
The sleeve slides onto the shaft and the bearing is mounted on the sleeve. Then the nut is tightened, which pushes the sleeve and expands the inner ring, reducing radial clearance. The reduction must be controlled with gauges or by measuring clearance.
Can I replace a FAG bearing with another brand?
Yes, equivalent alternatives from other brands exist. However, if the application is critical, it is recommended to keep the original brand to ensure the same performance. At MR we advise you on the best option.
How do I identify the FAG bearing I need?
You can look for the code engraved on the bearing (for example, 6205-2RS). If it is not legible, measure inner diameter, outer diameter and width, and send us a photo. With that data we help you identify it.
What lubricant do I use for FAG bearings?
It depends on speed, temperature and load. In general, lithium greases are used for standard applications. For high temperatures or speeds, special greases are required. Consult us and we will recommend the right one.
