Barrel Roller Bearings FAG 20315 -MB

The FAG 20315-MB spherical roller bearing, measuring 75 × 160 × 37 mm, offers high radial load-carrying capacity and reliably compensates for misalignment.

The 20315 -MB spherical roller bearing from FAG is a single-row, angular-contact roller bearing designed for industrial applications. With a bore of 75 mm, an outside diameter of 160 mm and a width of 37 mm, it is primarily designed to accommodate heavy radial loads. Thanks to its barrel-shaped rollers, this design compensates for misalignment between the shaft and housing. The open bearing is suitable for designs where external seals and a targeted lubricant supply are provided.

What is the 20315-MB barrel bearing suitable for in operation?

This roller bearing is primarily used in applications involving high radial forces, particularly where shaft deflection or misalignment occurs. Typical applications include bearing locations in general mechanical engineering with demanding load profiles. The solid brass cage guides the rolling elements reliably, even under vibration and shock loads. Thanks to the angle-adjustable design, the rotational movement remains smooth even with slight misalignments.

What advantages does the brass cage in this design offer?

The integrated brass cage gives the bearing high mechanical strength and thermal resistance within a temperature range of –30 to +150 degrees. Thanks to its solid construction, the cage withstands mechanical stresses during continuous operation. Manufactured with standard radial bearing clearance and tolerance class P0/PN (ABEC 1), the component fits precisely into standardised bearing seats. Lubrication is carried out according to the specific application, using either grease or lubricating oil.
