FAG: how to choose the bearing by application

FAG special bearings are designed for requirements that go beyond standards, such as high precision, combined loads or reduced spaces. They are common in machine tools, robotics and measuring equipment where rigidity and rotational accuracy are decisive. When choosing them, it is key to analyze the shaft arrangement and the forces acting at each support point.

In our catalog we sell references such as YRT50, an axial-radial bearing used in rotary tables of machine tools. This type of bearing is bolted directly to the machine and solves both axial and radial support in a single piece. To order them, it is best to send the complete code engraved on the part or, if it is not legible, the main dimensions and a photo.

A common mistake is replacing a special bearing with a standard one of similar dimensions, which can cause premature failures. You also have to verify the fit and the recommended lubrication for each model. If you have doubts about the selection, send us the code and the equipment data and we will quote the exact reference for your application.

FAG spherical roller bearings support very high radial loads and moderate axial loads, and allow shaft misalignments without losing performance. They are the typical choice in mining equipment, mills, industrial fans and belt conveyors. The spherical raceway of the outer ring gives them that self-aligning capacity.

We work with codes such as 20222-MB and 24896-MB, two references of very different sizes and series within this line. When requesting a quote, it is important to indicate whether the bearing works with vibration or impact loads, because that defines the internal clearance and the cage type. It is also advisable to check the condition of the housings and the shaft fixing system.

A common mistake is mounting these bearings without respecting the specified radial clearance, which generates overheating. Another is not considering adequate lubrication for dusty or humid environments. We distribute FAG spherical roller bearings for different applications and help you confirm the correct reference from the code or dimensions.

FAG cylindrical roller bearings stand out for supporting high radial loads, and the caged versions also work well at high speeds. They are common in electric motors, gearboxes, pumps and rolling mills. Their design allows axial displacement between rings in some types, which facilitates thermal expansion of the shaft.

In this line we sell references such as SL182226 and SL183018, full-complement cylindrical roller bearings without a cage, which prioritize radial load capacity over speed. To choose the correct model, you have to evaluate the magnitude of the load, the rotation speed and whether axial support is needed in one or both directions. It is also essential to verify the fit on the shaft and in the housing.

A usual mistake is mounting a cylindrical roller bearing without allowing for thermal expansion, which can lock the bearing. Another is replacing a caged bearing with a non-caged one, or vice versa, without checking the equipment's operating speed. We quote the FAG cylindrical roller bearing you need just by sending us the code or the main dimensions.

FAG tapered roller bearings support combined radial and axial loads, and are common in vehicle wheels, gearboxes and spindles. Their tapered geometry allows adjusting the internal clearance during mounting, which gives rigidity to the system. They are generally mounted in pairs, face-to-face or in tandem, depending on the direction of the axial load.

We distribute codes such as 33115 and 32326, which belong to metric series. When ordering a tapered roller bearing, it is key to report whether it is used in a single or paired configuration, and the predominant axial load direction. It is also advisable to indicate the type of fit and whether there is preload, because that changes the required internal clearance.

A common mistake is over-adjusting the tapered roller bearing during mounting, which generates excess temperature and premature wear. Another is not respecting the recommended tightening torque for the fixing nut. If you have the engraved code or the dimensions, we quote the exact FAG tapered roller bearing for your equipment.

FAG deep groove ball bearings are the most versatile for moderate radial and axial loads. They are used in electric motors, household appliances, small pumps and countless industrial machines. Their simple design allows high speeds and quiet operation, with low maintenance needs.

We sell references such as 6012 and 6030, two sizes of the same series with different bore diameters. When choosing a deep groove ball bearing, you have to consider the seal or shield: 2RS for rubber seal on both sides, 2Z for metal shield, and C3 for internal clearance greater than normal. It is also important to verify the fit on the shaft and the housing.

A frequent mistake is using an open bearing in a dusty or humid environment, which shortens its service life. Another is not respecting the specified internal clearance, especially in applications with temperature changes. We quote the FAG deep groove ball bearing you need just by sending us the code or dimensions, and we confirm the seal and clearance that correspond.

FAG angular contact bearings are designed to support combined loads, with a predominance of axial load in one direction. They are typical in pumps, compressors, gearboxes and machine tool spindles. They are mounted in pairs or sets to support axial loads in both directions and achieve high rigidity.

In this category we work with series such as 7200 and 7300, single row, and 3200, double row. When requesting a quote, it is key to indicate whether the bearing is used individually or in a pair, and the axial load direction. It is also advisable to report whether preload is required, because that defines the internal clearance and the performance of the assembly.

A common mistake is mounting an angular contact bearing backwards, which cancels its axial load capacity. Another is not respecting the O or X arrangement as specified by the equipment manufacturer. We distribute FAG angular contact bearings for different applications and help you confirm the correct reference.

FAG thrust ball bearings support pure axial loads in one direction, as in winches, rotary tables and lifting systems. Self-aligning ball bearings, on the other hand, allow misalignments and light axial loads, and are useful in applications where the shaft can flex. In thrust bearings, the correct alignment of the support washers is key.

We sell references from these subcategories, such as series 51100 and 51200 for thrust bearings, and series 1200 and 1300 for self-aligning ball bearings. When ordering them, it is important to indicate whether the axial load is in one direction or alternating, and whether there are additional radial loads. It is also advisable to verify the condition of the support surfaces and the lubrication system.

A frequent mistake is using a thrust ball bearing where there is radial load, which causes rapid failures. Another is not respecting the alignment between the washers, generating vibrations and wear. We quote the FAG thrust or self-aligning bearing you need just by sending us the code, the dimensions or a photo of the part.
