FAG spherical roller bearings are self-aligning double-row components designed to support high radial loads and axial loads in both directions, even when the shaft has angular misalignment. Their self-aligning design makes them suitable for equipment with shaft deflection or misaligned mounting. MR Accesorios Industriales supplies this line as an official brand, with technical advice to select the correct part number for the application.

The designation of this series combines a five-digit base number with suffixes indicating design features. For example, in 20217-K-MB-C3, the prefix 202 corresponds to the spherical roller series; the following two digits (17) indicate the size; the letter K indicates a tapered bore; MB designates the machined brass cage; and C3 sets an internal radial clearance greater than normal. Cases such as 20218-K-MB-C3 or 20220-K-MB-C3 follow the same logic, varying the size.

These bearings are used in Argentine industries such as cement, mining, steel, paper and material handling. They appear in gearboxes, chain conveyors, mills, crushers, industrial fans and paper machines, where loads are high and shafts may deflect. Their self-aligning capability absorbs permanent or temporary misalignment, reducing the risk of premature failure.

To select the correct bearing, consider radial and axial load, rotation speed and environmental conditions. The tapered bore (suffix K) requires a suitable mounting sleeve to secure it to the shaft. The machined brass cage (MB) offers greater strength in severe applications. C3 clearance is recommended when there are thermal gradients or interference fits. Lubrication and sealing must be chosen according to the contamination level and working temperature.

When looking for equivalents from other brands, verify that the main dimensions, bore type, internal clearance and cage design match. Codes may vary between manufacturers, but a bearing with a similar designation is usually interchangeable if those characteristics are respected. Always confirm with the manufacturer's data sheet before replacing a critical component.
