How the 3213-A-2Z model number is decoded

3213 A-2Z is the capped double-row angular-contact ball bearing for a 65 mm shaft, 65×120×38.1 mm, greased and sealed (or shielded) for life at the SKF works. A on this double-row bearing means no filling slots, so both ball rows retain their full complement. -2Z marks a sheet-metal shield on each side: non-contacting, grease-retention and dust protection with negligible drag, the bearing remaining open-style relubricatable only through the shield clearance. Envelope 65×120×38.1 mm (2.559×4.724×1.5 in), 27.5 mm radial section height, C 80.6 kN, C0 73.5 kN, Pu 3.1 kN.SKF publishes only the 4,800 r/min limiting speed for this execution, catalogue mass 1750 g. Mass and section check: 1750 g inside the 65×120×38.1 mm outline leaves a 27.5 mm radial section, and the 73.5 kN static rating is 0.91× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Sizing arithmetic on the 65 mm bore: 80.6 kN C divided by the 27.5 mm radial section height gives 2.9 kN per section millimetre; the 1750 g mass and 4 % Pu/C share frame the light-load floor for the adjusted-life check. Bore-to-OD planning: OD 120 over bore 65 is a 1.85× step for this size, and the 38.1 mm width gives a bore/width ratio of 1.71; use these ratios when housing space around the 65 mm shaft is the first constraint. Shielded execution note: the two sheet-metal -2Z covers clip into the outer ring without contacting the inner ring, giving grease retention and coarse-dust protection at virtually no friction; the cavity is factory-greased and the shield arrangement suits dry, moderately dusty positions rather than wash-down duty, where the A-2RS1 contact-seal order number is the alternative.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The shields/seals do not make the bearing waterproof under immersion or pressure washing; select external sealing for wet or wash-down duty.
• The non-contact shields cap the speed with negligible drag: no relubrication is provided for, so mounting cleanliness decides much of the real grease life.
• Never wash 3213-A-2Z in solvent: the lifetime grease fill cannot be replaced once flushed out.
• Never wash 3213-A-2Z in solvent: the lifetime grease fill cannot be replaced once flushed out.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 3213 A-2Z as the double shielded execution; the other order numbers of the 3213 size are different products and may carry different ratings — always quote the full designation when purchasing.
