Decoding the designation

Series: 22200 — the wide double-row spherical roller series. J30: Internal Clearance C3, one step wider than normal. B33: SNR’s code for the W33 lubrication feature. The bore is straight and cylindrical, so the inner ring seats directly on the shaft.

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.

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 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 a tight interference fit on the shaft and a working temperature difference between inner and outer ring.
