Torrington22213KMW33C3Double-Row Spherical Roller Bearing, 65 x 120 x 31 mm, 1:12 Tapered Bore, Machined Brass Cage, W33 Lubrication, C3 Clearance

Product Description

What this part is:

A Torrington 22213 K.M.W33.C3 double-row spherical roller bearing measuring 65 mm bore x 120 mm outside diameter x 31 mm wide. It has a 1:12 tapered bore, a machined brass cage, a lubrication groove and three holes through the outer ring, and C3 radial internal clearance. Unit Quantity: 1 Pc, one complete non-separable bearing with inner ring, two rows of spherical rollers, machined brass cage and outer ring. Spherical roller bearings carry radial load plus axial load in both directions, and the spherical outer raceway lets the bearing self-align to shaft deflection or housing misalignment.

Decoding the designation:

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

13 — bore code, 13 x 5 = 65 mm bore.

K — tapered bore, taper 1:12.

M — machined brass cage.

W33 — circumferential lubrication groove around the outer ring outside diameter plus three radial lubrication holes through to the raceway.

C3 — radial internal clearance greater than normal.

Dimensions and mounting:

Chamfer (rs min): 1.5 mm. Fillet (ras max): 1.5 mm. Shaft Abutment (da min): 74 mm. Housing Abutment (Da max): 111 mm. Axial Load Factors: e 0.24, Y1 2.79, Y2 4.15, Y0 2.73. The 1:12 taper mounts on an H313 adapter sleeve (55 mm shaft seat) with a KM13 locknut and MB13 lockwasher, or on a machined 1:12 tapered shaft seat. Matching Withdrawal Sleeve: AH313. The sleeve, nut and washer are separate part numbers.

Compatibility and replacement:

Torrington is now part of Timken; the current-brand equivalent is a Timken 22213 KEMW33C3 or 22213 KEMBW33C3, both tapered-bore brass-cage 22213s with the lubrication groove and holes. Cross-references with brass cages: SKF 22213 CAK/C3W33, FAG 22213-E1A-K-M-C3, NSK 22213 CAMKE4C3, NTN 22213 EMKW33C3, Koyo 22213RKW33C3. Steel-caged tapered-bore versions in the same seat: Timken 22213 KEJW33C3, SKF 22213 CCK/C3W33, NSK 22213 CDKE4C3, NTN 22213EAKW33C3. The 22213MW33C3 is the straight-bore form of the same bearing.
