FAG22232MC4W33Spherical Roller Bearing – 160 mm ID, 290 mm OD, 80 mm Width, Straight Bore, Open, W33 Lubrication Groove, C4 Extra-Loose Clearance, Machined Brass Cage

Product Description

What this part is

FAG 22232MC4W33 double-row spherical roller bearing. Series 222. Bore: 160 mm, straight. Outside diameter: 290 mm. Width: 80 mm. Two rows of barrel rollers on a common spherical outer raceway, so the bearing accommodates shaft misalignment and carries thrust in both directions as well as radial load.

Decoding the designation

M: machined brass cage. C4: extra-loose radial internal clearance, wider than C3 and wider again than normal. W33: annular lubrication groove in the outer ring with three radial feed holes. Bore form: straight, shaft-mounted directly on a 160 mm seat. Carton and punctuation variants in circulation: 22232 M C4 W33, 22232MC4W33, 22232-M-C4-W33, 22232 E1 M M C4 W33, 22232E1A.M.C4, 22232E.

What these specs mean in practice

Basic dynamic radial load rating: 1 000 kN (224 808 lbf). Basic static radial load rating: 1 220 kN (274 268 lbf). On a double-row spherical roller bearing the static rating sits above the dynamic rating — that is the normal relationship for the type. Limiting speed: 2 000 rpm. C4 clearance leaves running clearance in a bearing that will see a heavy interference fit, a hot inner ring or a large temperature difference between rings, which is standard practice on kiln fans, dryer rolls and vibrating equipment. A machined brass cage tolerates shock loading, high temperature and marginal lubrication better than a pressed steel cage.

Relubrication

W33 annular groove in the outer ring with three radial lubrication holes. Grease or oil reaches both roller rows through the housing without dismantling.

Quantity and configuration

One bearing, complete: outer ring, inner ring, two roller rows and machined brass cages. Open on both faces.

Fitting notes

Straight bore, pressed onto a 160 mm shaft seat. Operating temperature range: -30 °C to 200 °C. Weight: 50.04 lb (22.08 kg).
