SKF2222-KMSelf-Aligning Ball Bearing – 110 mm ID, 200 mm OD, 53 mm Width, Tapered 1:12 Bore, Machined Brass Cage, Open, CN Internal Clearance, Two Ball Rows

Product Description

What this part is

SKF 2222-KM self-aligning ball bearing. Series 2200. Bore: 110 mm. Outside diameter: 200 mm. Width: 53 mm. Two rows of balls running on a common spherical raceway in the outer ring. Rolling elements: balls, 2 rows.

Decoding the designation

K: tapered bore, 1:12 taper. M: machined brass cage. Base number: 2222, the 2200 series. Internal clearance: CN, the normal class. Punctuation variants in circulation: 2222 K M, 2222KM, 2222-K-M, 2222K.

What these specs mean in practice

Basic dynamic load rating: 124 kN (27 876 lbf). Basic static load rating: 52 kN (11 690 lbf). Reference speed: 6 000 rpm. Limiting speed: 4 300 rpm. The spherical outer raceway lets the inner ring, ball rows and cage swivel inside the outer ring, so the bearing runs without induced stress on a shaft that deflects or on a housing bored out of line. Friction is the lowest of any rolling bearing type, which is why the family carries a high limiting speed for its size.

Bore form and adapter sleeve

The 1:12 tapered bore mounts on an H 322 adapter sleeve, a separate part, with a KM 22 locknut and an MB 22 lock washer. The sleeve lets the bearing sit anywhere along a plain shaft, and driving it up the taper sets the radial internal clearance during assembly.

Quantity and configuration

One bearing, complete: outer ring, inner ring, both ball rows and the machined brass cage. Open on both faces.

Fitting notes

Operating temperature range: -30 °C to 120 °C. Weight: 16.00 lb. Machined brass cages run at higher temperatures and tolerate shock and acceleration better than pressed steel.

Interchange guidance

Same-envelope designations: FAG 2222-K-M, NTN 2222K, Koyo 2222K, NSK 2222K, SNR 2222K. Related sizes: 2222 (straight bore, mounted direct on the shaft) and 22222 EK/C3 (spherical roller in the same 110 x 200 x 53 mm envelope, a different bearing type).
