The FAG B-2RZ-TVH series angular contact bearings are ball bearings with raceways designed to support combined radial and axial loads in a single direction. Their sealed design on both sides and their polyamide cage make them suitable for applications requiring low maintenance and protection against contaminants. They are used in pumps, compressors, fans and transmission equipment operating at moderate and high speeds. MR Accesorios Industriales sells this line in Buenos Aires, Argentina, and advises you to choose the correct code.

The series designation is read in blocks: the base number identifies the bearing size (for example, 3000, 3001, 3002, etc., which in practice correspond to standard shaft diameters). The suffix B indicates a 40° contact angle, suitable for moderate axial loads. Then, 2RZ indicates that the bearing has low-friction seals on both sides, which retain lubricant and block dust ingress. Finally, TVH describes the glass fiber reinforced polyamide cage, ball-centered. Thus, a code such as 3005-B-2RZ-TVH is interpreted as a bearing of the 3005 series, with B angle, double seal and TVH cage.

These bearings are used in the food and beverage, chemical, petrochemical and water treatment industries, among others. In Argentina they are commonly found in centrifugal pumps, screw compressors, industrial fans, gearboxes and machine tools. Their ability to support combined loads makes them useful in transmission shafts with helical gears or belts, where axial forces appear. They are also used in packaging and conveying equipment, where cleanliness and low heat generation are important.

To select correctly, take into account the direction of the axial load: being single-row angular contact, they support thrust in one direction only, so they are usually mounted in pairs (tandem, back-to-back or face-to-face) to cover both directions. The 2RZ seal is already lubricated at the factory, so it does not require additional greasing in most cases; if the environment is very humid or has vapors, consider a more robust seal. The TVH cage tolerates moderate operating temperatures. During assembly, it is key to align the supports well and apply the axial clearance recommended by the manufacturer to avoid excessive preload.

When looking for equivalents, angular contact bearings are identified by their complete designation, which includes series, angle, seal and cage. Different manufacturers may use their own nomenclature, but dimensional codes usually match. If you need to replace an existing bearing, the safest approach is to compare the main dimensions (bore, outer diameter and width) and the type of seal. MR Accesorios Industriales sells the FAG brand and can offer you equivalent alternatives.
