Timken22215CJW33Double-Row Spherical Roller Bearing 75 x 130 x 31 mm, Straight Bore, Open, CN Clearance, W33 Lubrication Groove and Three Holes

Product Description

What this part is

A Timken 22215CJW33 double-row spherical roller bearing, straight bore, open on both faces, with a lubrication groove and three feed holes in the outer ring.

Decoding the designation

222 — spherical roller dimension series 222.
15 — bore code, giving a 75 mm bore.
W33 — lubrication groove in the outer ring plus three radial feed holes.
No K or K30 in the designation, so the bore is straight.
No clearance suffix, so internal clearance is CN.

What these specs mean in practice

The two roller rows run on a common spherical outer raceway, so the inner ring and roller set can tilt within the outer ring and absorb shaft misalignment or housing misalignment that would destroy a cylindrical or tapered bearing. Two rows on opposed contact lines carry thrust in both directions as well as heavy radial load. The W33 groove and holes let grease or oil be fed through the housing straight into the roller path, which is what makes relubrication practical on a bearing that is expected to run for years in a dirty position. CN clearance is the standard fit for a straight bore on an interference shaft seat at normal running temperature.

Interchange guidance

ISO base number 22215. Searchable forms are 22215CJW33, 22215-CJ-W33, 22215 CJ W33 and 22215W33. A 22215KCJW33 has a 1:12 tapered bore and needs an adapter sleeve, and a 22215CJ without the W33 has no relubrication provision, so both are related sizes rather than interchanges. A 22215 in C3 clearance is likewise a related size.
