FAG22215E1AMSpherical Roller Bearing – 75 mm ID, 130 mm OD, 31 mm Width, Straight Bore, Open, CN Clearance, Machined Brass Cage

Product Description

What this part is

FAG 22215E1A.M double-row spherical roller bearing. Bore 75 mm, outside diameter 130 mm, width 31 mm, straight cylindrical bore, open on both faces, machined brass cage. Weight 4.30 lbs. FAG is a Schaeffler brand.

Decoding the designation

222 identifies a double-row spherical roller bearing in the 22 dimension series. The bore code 15 gives 75 mm. E1A is the FAG reinforced internal execution, with a modified roller and raceway geometry that raises capacity within the same envelope. M is the machined solid brass cage. There is no K suffix, so the bore is straight rather than 1:12 tapered.

Bore form and mounting

Straight cylindrical bore, mounted directly on the shaft seat with an interference fit. The tapered-bore counterpart, 22215EK, is the version that runs on an H315 adapter sleeve.

What these specs mean in practice

A double-row spherical roller bearing accommodates shaft misalignment through the spherical outer raceway while carrying heavy radial load, and it takes thrust in both directions. Dynamic capacity is 200 kN and static capacity 212 kN, with a limiting speed of 5,600 rpm. The machined brass cage tolerates high temperature, shock load and marginal lubrication better than a pressed steel cage, and supports the 200 °C upper operating limit. Normal CN radial internal clearance suits ordinary interference fits at moderate temperature differentials.

Quantity and configuration

One bearing. Two rows of symmetrical barrel rollers, open, without a snap-ring groove and without a lubrication groove or feed holes.

Fitting notes

The shaft seat is machined to a k5 or m5 class fit for rotating-inner-ring load and the housing bore to H7, with the bearing pressed or heat-mounted square to the shoulder. Oil or grease lubrication both suit the brass cage.

Interchange guidance

SKF 22215 EM, NSK 22215EAME4 and Koyo 22215RM are same-specification interchanges in this size with a machined brass cage. FAG 22215-E1A-XL-M is the current Schaeffler designation for the same bearing. SNR 22215EMW33 adds a lubrication groove and three feed holes in the outer ring, so it is a related build. 22215EK shares the envelope with a 1:12 tapered bore, making it a related size that mounts differently. 22215E1A.M.C3 is the same bearing at C3 clearance.
