How to read FAG 2218-TVH
- 22Series
- Self-aligning ball bearings, 22 series. For the same bore, each series has a different outside diameter and width.
- 18Bore
- 90 mm bore: 18 × 5.
- TVHSuffix
- FAG suffix: it defines the variant (sealing, cage, internal clearance or other features).
2218 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description

FAG TVH series self-aligning ball bearings are single-row self-aligning bearings with two raceways in the outer ring and a spherical surface that compensates for angular misalignment between shaft and housing. They are used in applications where perfect alignment cannot be guaranteed, such as belt drives, fans or agricultural equipment. MR Accesorios Industriales supplies this line with technical advice so you can choose the correct part number.
The TVH series designation is read step by step. The initial numbers identify the size and series: for example, 108-TVH, 126-TVH or 1200-TVH correspond to self-aligning ball bearings of different dimensions. The TVH suffix indicates that the cage is made of glass fiber reinforced polyamide, suitable for moderate temperatures and high speed. In four-digit codes, such as 1200-TVH or 1202-TVH, the first two digits indicate the series and the last two the bore diameter. To correctly interpret each code, it is advisable to consult the dimension table.
These bearings are used in equipment where the shaft may flex or become slightly misaligned: belt and chain drives, fans, centrifugal pumps, textile machines, agricultural equipment and conveyors. In Argentine industry they appear in food processing plants, cement plants, paper mills and the metalworking sector. Their self-aligning capability reduces stress on the shaft and housing, which extends the service life of the assembly. They are a frequent choice when the mounting does not allow precise alignment or when the structure is flexible.
To select the correct bearing, take into account the shaft diameter, radial and axial loads, and rotational speed. The TVH series with polyamide cage is suitable for applications with adequate lubrication and temperatures that do not exceed the material limits. During mounting, verify that the housing and shaft are clean and free of burrs; self-alignment does not correct excessive concentricity errors. Lubrication must be as specified by the manufacturer and sealing will depend on the environment: in the presence of dust or moisture, it is advisable to evaluate sealed variants.
Regarding equivalents, self-aligning ball bearings are manufactured under international standards that allow part numbers to be interchanged between brands, but each manufacturer may have its own suffixes for cage, clearance or sealing. The FAG TVH series may have equivalents in other brands with different designations; it is always advisable to verify dimensions and tolerances before replacing. MR Accesorios Industriales supplies FAG as a brand and can advise you on interchangeability without compromising equipment performance.
If you need an FAG TVH series self-aligning ball bearing, send us the complete part number or the shaft and housing dimensions via WhatsApp. At MR Accesorios Industriales we advise you so you receive the correct part promptly. We can also quote other variants of the FAG line if your application requires sealing, special clearance or high-temperature materials.

Frequently Asked Questions
- What are the dimensions of the FAG 2218-TVH bearing?
- The FAG 2218-TVH bearing has a 90 mm bore, a 160 mm outside diameter and a 40 mm width (90 x 160 x 40 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 2218.
- What does the TVH suffix mean in an FAG bearing?
- The TVH suffix indicates that the bearing has a glass fiber reinforced polyamide cage, suitable for high-speed applications and moderate temperatures. It is an FAG internal designation that does not affect the main dimensions of the bearing.
- How do I choose the right self-aligning bearing for my equipment?
- You need to know the shaft diameter, radial and axial loads, and rotational speed. The environment and lubrication also play a role. With that data, we can recommend the exact part number within the TVH series or a sealed variant if there is contamination.
- Can I replace a self-aligning bearing from another brand with an FAG one?
- In general yes, if dimensions and tolerances match. Self-aligning bearings follow international standards, but each manufacturer uses its own suffixes for cage or clearance. Verify the complete part number and consult us to confirm the equivalence before mounting.
