ROLLWAY22213GMEXW33Double Row Spherical Roller Bearing – Straight Bore, 65 mm Bore x 120 mm OD x 31 mm Width, Open, Machined Brass Cage, W33 Lubrication

Product Description

What this part is

Rollway 22213GMEXW33 double-row spherical roller bearing. Bore: 65 mm. Outside diameter: 120 mm. Width: 31 mm. Series: 22213, the 222 dimension series. Number Of Rows: 2. Bore form: straight. Closure: open. Rolling elements: barrel-form spherical rollers in a machined brass cage.

Decoding the designation

222 gives the dimension series and 13 the bore code, which is 65 mm. W33 is a lubrication groove in the outer ring with three radial feed holes. The bore is straight, so the bearing mounts directly on the shaft seat. Internal Clearance: CN, the normal class. Precision Class: ABEC 1 / P0. The GMEX token is a Rollway execution marking and is carried as a searchable part-number variant.

What these specs mean in practice

Dynamic Load Rating: 151 kN. Static Load Rating: 167 kN. Limiting Speed: 3,400 rpm. Two rows of spherical rollers seat on a common sphered outer raceway, so the bearing self-aligns and absorbs shaft deflection and housing misalignment while carrying heavy radial load and thrust in both directions. The machined brass cage suits shock loading and higher temperature than a pressed cage. Operating range: -40 °C to 200 °C.

Quantity and configuration

Unit Quantity: 1 Pc. Single bearing, supplied open. Item weight: 3.50 lb.

Fitting notes

Straight bore, mounted directly on the shaft seat. The W33 groove and holes line up with a feed port in the housing so grease or oil reaches both roller rows from the loaded zone outward.

Interchange guidance

The direct straight-bore equivalents on this envelope are SKF 22213 E and FAG 22213E1.M, both 65 x 120 x 31 mm in the same series and clearance class. SKF 22213 EK and FAG 22213-E1-K carry a 1:12 tapered bore and mount on an adapter sleeve, which makes them a related size.
