Decoding the designation

Series: 222 — the wide double-row spherical roller dimension series. Bore code 10: 50 mm bore. K: 1:12 tapered bore. V: internal design modification. No clearance suffix, so the clearance is CN, the normal radial class.

Bore form and mounting hardware

The bore is tapered 1:12 and the 50 mm figure is the small-end bore diameter. The matching adapter sleeve is an SNR H310 — its tapered outside diameter is 50 mm and its cylindrical shaft seat is 45 mm, so the bearing mounts on a 45 mm plain shaft. The matching lock nut is a KM10 and the matching lock washer is an MB10. The taper also seats directly on a 1:12 machined shaft seat.

What these specs mean in practice

Two rows of barrel rollers run on a common spherical raceway in the outer ring, so the inner ring and roller set swivel inside the outer ring. Permissible Misalignment: 0.5° at normal load, which absorbs shaft deflection and housing bore misalignment. The large roller-to-raceway contact area carries heavy shock and dead load, and the double-row arrangement takes axial load in both directions alongside the radial load. CN clearance suits a shaft-mounted fit at ambient running temperature.

Quantity and configuration

Unit Quantity: 2 Pcs. Two complete bearings, each one outer ring, two roller rows, cage and inner ring, assembled and open on both faces. New old stock, stained.
