Brass-cage specification for the 22256 size
Keep CA/W33 in the quotation designation. The separately listed 22256 CC/W33 uses a different cage design; do not shorten both requests to 22256 or assume that all suffix configurations are interchangeable.
CA cage and W33 lubrication arrangement
CA identifies the machined brass cage configuration in this catalogue. W33 specifies an outer-ring lubrication groove and holes. Keep additional clearance or bore suffixes on your purchase request if they appear on the original marking; the designation shown here does not automatically include C3 clearance or a tapered bore.
Application review before ordering
This bearing type is considered for radial-load applications that also require accommodation of shaft misalignment. For machinery such as conveyors, processing equipment and industrial drives, suitability still depends on the actual radial and axial loads, speed, lubrication and support arrangement. Ask for a drawing review rather than selecting solely by the model number.
