Bearings, couplings and housings for hydroelectric and thermal power plants

In hydroelectric and thermal power plants, rotating equipment such as pumps, fans and auxiliary turbines depend on high-reliability bearings. Operating conditions are often demanding: heavy loads, variable speeds and environments with humidity or high temperatures. Therefore, selecting the right bearing is critical to avoid unplanned downtime.

At MR Accesorios Industriales, from Buenos Aires, Argentina, we supply spherical roller, cylindrical roller and angular contact bearings for these applications. We work with recognized brands such as SKF, FAG, LINK-BELT and TIMKEN, and we quote the exact code you need.

Spherical roller bearings are ideal for hydroelectric and thermal power plants because they support combined radial and axial loads and compensate for shaft misalignment. In large centrifugal pumps and industrial fans, where loads are high and speeds moderate, these bearings ensure a long service life.

For example, SKF codes 22325 and 22361, or FAG 20222-MB and 20240-MB, are typical references for these applications. We also work with the LINK-BELT line, such as models 6203U and 22318, which offer robustness and durability.

When choosing a spherical roller bearing, consider the cage type and internal clearance. For high-temperature applications, a C3 clearance may be necessary. Our technical team advises you on the selection.

Cylindrical roller bearings stand out for their ability to withstand high radial loads and operate at high speeds. In thermal power plants, they are used in electric motors, generators and feed pumps. Their design allows for easy disassembly, which facilitates maintenance.

Within this category, we supply references such as SKF N3055 and RNU 305, and FAG SL182226 and SL183018. We also offer LINK-BELT options, such as 6217 and 5326, which are widely used in the energy industry.

It is important to verify the bearing configuration: some are single-row, others double-row, and may include guide flanges. If you have doubts, send us a photo of the part and we will help you identify it.

Angular contact bearings are the choice when radial and axial loads are combined and high rotational precision is required. In hydroelectric power plants, they are used in high-pressure pumps and turbine control systems. Their design allows them to support axial loads in one direction, so they are often mounted in pairs.

We work with codes such as SKF 7417 and 7453, FAG 3314 and 3315, and TIMKEN 7310 B and 7211 B. The letter B indicates a 40° contact angle, suitable for moderate axial loads.

When selecting an angular contact bearing, consider the arrangement (face-to-face, back-to-back or tandem) according to the direction of the loads. We advise you to choose the correct configuration.

SNL split housings are a practical solution for mounting bearings on long shafts, such as those of fans and pumps. Being split, they allow inspection and replacement of the bearing without dismantling the entire shaft, which reduces downtime.

At MR we supply SKF SNL housings, such as SNL 211 and SNL 216, which adapt to bearings of different series. These housings include seals and lubrication systems to protect the bearing in dusty or humid environments.

To choose the correct housing, you need to know the shaft diameter and the bearing type. If you are not sure, send us the measurements and we will indicate the appropriate alternative.

Proper lubrication is essential to prolong the life of bearings in hydroelectric and thermal power plants. Greases and oils must resist high temperatures, water and contaminants. In our greases and lubrication category you will find specific products for these conditions.

In addition, we have mounting and maintenance tools that facilitate the installation and removal of bearings without damaging them. This includes induction heaters, pullers and hook wrenches.

Well-planned preventive maintenance, with the correct lubrication and appropriate tools, reduces failures and operating costs. We help you define the lubrication plan for your equipment.

To quote, we need the bearing code, the measurement or a photo of the part. With that information, we will respond promptly with the proposal. We ship throughout the country from Buenos Aires, Argentina.

If your application is critical and you are not sure of the correct bearing, our technical team can advise you. Send us the load, speed and environmental conditions data, and we will recommend the best option.
