SKF22214-CKJ-C5-W33Double-Row Spherical Roller Bearing, 70 x 125 x 31 mm, 1:12 Tapered Bore, Stamped Steel Cages, W33 Lubrication, C5 Extra-Loose Clearance

Product Description

What this part is:

SKF 22214 CKJ C5 W33 double-row spherical roller bearing: 70 mm bore, 125 mm outside diameter, 31 mm width. 1:12 tapered bore, stamped steel cages on a guide ring, outer-ring lubrication groove with three holes, C5 radial internal clearance. Unit Quantity: 1 Pc, one complete non-separable bearing.

Decoding the designation:

222 — double-row spherical roller bearing, ISO dimension series 22.

14 — bore code; 14 x 5 = 70 mm bore.

C — SKF internal design: optimised internal geometry with a guide ring between the roller rows in place of a fixed central rib.

K — tapered bore, taper 1:12.

J — stamped steel cage, centred on the inner ring.

C5 — radial internal clearance greater than C4, which is itself greater than C3.

W33 — circumferential lubrication groove around the outer ring plus three radial lubrication holes to the raceway, delivering grease or oil between the two roller rows.

Compatibility and replacement:

Tapered-bore 70 x 125 x 31 mm bearings with C5 clearance from other makers, each a different internal design: SKF 22214 EK/C5W33, FAG 22214-E1-K-C5, Timken 22214KEJW33C5, NTN 22214EAKW33C5. SKF 22214 CCK/C4W33 is the same size at C4 clearance. The same designation without the K suffix has a straight cylindrical bore; a brass-caged version carries CA in SKF nomenclature.
