FAG22215MDouble Row Spherical Roller Bearing, Straight Bore, 75 x 130 x 31 mm, Open, Brass Cage, CN Clearance

Product Description

What this part is

A FAG 22215M double-row spherical roller bearing, 75 mm bore, 130 mm outside diameter, 31 mm width. Straight cylindrical bore, open, machined brass cage, normal precision class, CN internal clearance.

Decoding the designation

222 identifies the double-row spherical roller bearing in the 22 dimension series, the wider of the two common spherical roller series. The bore code 15 gives 75 mm. M is the machined brass cage. There is no K in the designation, so the bore is straight and the bearing mounts directly on the shaft rather than on an adapter sleeve. There is no W33, so the outer ring has no lubrication groove or feed holes.

What these specs mean in practice

The two rows of barrel rollers run on a common spherical outer raceway, so the inner ring and roller set swivel within the outer ring and the bearing accommodates shaft misalignment and housing deflection while carrying very heavy radial load. A double-row spherical roller bearing takes thrust in both directions. The machined brass cage tolerates higher temperature and heavier shock than a pressed steel cage and is the usual choice for oil-lubricated and vibrating-screen duty.

Quantity and configuration

1 Pc. Complete bearing: outer ring, two roller rows, cage and inner ring. Open both faces, without snap ring.

Fitting notes

The straight bore takes an interference fit directly on a cylindrical shaft seat, with induction or oil-bath heating for mounting. Relubrication is through the housing, since the outer ring carries no lubrication groove.

Interchange guidance

SKF 22215 E and NTN 22215EMD1 are same-envelope equivalents in the reinforced design. FAG 22215K is a related size with a 1:12 tapered bore that mounts on an H315 adapter sleeve; FAG 22215M.W33 is a related size with a lubrication groove and three feed holes in the outer ring.
