FAG spherical roller bearings are double-row, self-aligning units built to carry heavy radial loads plus axial loads in both directions, even when the shaft is misaligned. That self-aligning behavior suits equipment where shafts deflect or mounting is not perfectly aligned. MR Industrial Accessories LLC supplies this line and can help you match the right part number to your application.

The part number tells you a lot once you know how to read it. Take 20217-K-MB-C3: the 202 prefix identifies the spherical roller series, the 17 that follows indicates the size, K means a tapered bore, MB points to a machined brass cage, and C3 sets internal radial clearance above normal. The same pattern applies to 20218-K-MB-C3 and 20220-K-MB-C3, with only the size digits changing.

These bearings show up in cement, mining, steel, paper and material handling operations. You will find them in gearboxes, chain conveyors, mills, crushers, industrial fans and paper machines, where loads are heavy and shafts can deflect. The self-aligning feature absorbs misalignment, whether permanent or temporary, which helps avoid premature failure.

Selection comes down to radial and axial load, speed and the operating environment. A tapered bore (K) needs a matching mounting sleeve to lock it onto the shaft. The machined brass cage (MB) adds strength in tough conditions. Choose C3 clearance when thermal gradients or interference fits are present. Lubrication and sealing should follow the contamination level and working temperature.

If you are comparing equivalents from other brands, check that main dimensions, bore type, internal clearance and cage design line up. Designations differ between makers, but a bearing with a similar code is often interchangeable when those characteristics match. Confirm against the manufacturer's data sheet before swapping a critical component.
