90 × 190 × 64 mm. self-aligning ball bearing has two rows of balls, a common spherical raceway in the outer ring and a tapered K bore. It accommodates angular misalignment between shaft and housing while carrying mainly radial load plus lighter axial load in both directions. It is well suited to positions where shaft deflection or alignment error cannot be fully avoided.
The dimensions are bore diameter d = 90 mm, outside diameter D = 190 mm and width 64 mm. Depending on the design, manufacturers may label width or height B, T or H; for tapered roller bearings, distinguish overall width T from ring widths B and C. Before ordering, compare the full designation, including suffixes, bearing design, seals or shields, internal clearance and the requirements of your bearing arrangement. If you are unsure, send us the full designation and, if available, a photograph of the original part.
