Decoding the designation

Series: 22200 — the wide double-row spherical roller series. V: internal design modification. K: 1:12 tapered bore. B33: SNR’s code for the W33 lubrication feature. J30: Internal Clearance C3, one step wider than normal. On a spherical roller bearing C3 is a normal, correct clearance selection.

The W33 lubrication feature

B33 is an annular groove machined around the outside diameter of the outer ring, with three radial holes drilled through to the roller path. The groove distributes lubricant circumferentially around the outer ring and the three holes carry it inward to the rolling elements. Lubricant: grease or oil — the same passages serve a grease gun, a single-point lubricator, a centralised grease system, an oil-mist feed or a circulating-oil system.

Bore form and adapter sleeve

The bore is tapered 1:12 and the 95 mm figure is the small-end bore diameter. The matching adapter sleeve is an SNR H319 — its tapered outside diameter is 95 mm and its cylindrical shaft seat is 85 mm, so the bearing mounts on an 85 mm plain shaft. The matching lock nut is a KM19 and the matching lock washer is an MB19. Driving the bearing up the sleeve taper sets the internal clearance by controlled radial expansion of the inner ring. 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 22200 series is the wide section of the spherical roller range and carries a higher radial rating than the 21300 section on the same bore. The double-row arrangement takes axial load in both directions alongside the radial load. The C3 class opens the radial internal clearance beyond CN, which suits the tight interference fit produced by sleeve mounting and a working temperature difference between inner and outer ring.
