Barrel Roller Bearings FAG 20316 -MB

FAG 20316 -MB spherical roller bearing (80x170x39 mm) with brass cage and standard clearance for angularly adjustable, heavy-duty industrial bearing arrangements.

The 20316 -MB spherical roller bearing is a single-row, self-aligning roller bearing designed for demanding mechanical loads. Thanks to the barrel-shaped rolling elements, this design automatically compensates for misalignment or shaft deflection during operation. This open roller bearing from FAG Wälzlager features a solid brass cage that guides the rollers precisely, even under vibration. With a bore of 80 mm, an outer diameter of 170 mm and a width of 39 mm, this component is particularly suitable for heavy-duty shaft mountings in mechanical and plant engineering.

In which applications does the 20316-MB spherical roller bearing compensate for shaft deflection?

Design engineers and maintenance technicians rely on this bearing when high radial loads coincide with possible shaft misalignment. The spherical outer ring raceway allows angular movements without causing excessive edge stresses on the roller edges. Typical applications include heavy-duty bearing arrangements subject to intermittent radial forces, where elastic shaft deflection occurs. The bearing absorbs these forces and, thanks to its angularly adjustable design, helps to prevent stress concentrations in the drive train.

What advantages does the brass cage offer in this spherical roller bearing?

The suffix -MB denotes a solid brass cage. Compared to sheet metal or plastic versions, brass offers high strength, good run-on properties and vibration damping. The bearing operates within a temperature range of -30 to +150 degrees. As this is an open bearing without an integrated seal, you should select the type of lubricant and relubrication intervals to suit the surrounding machine housing. The bearing is manufactured to the standard tolerance class P0/PN or ABEC 1 with standard radial clearance.
