How the 3215-A-2Z model number is decoded

3215 A-2Z is the capped double-row angular-contact ball bearing for a 75 mm shaft, 75×130×41.3 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 75×130×41.3 mm (2.953×5.118×1.626 in), 27.5 mm radial section height, C 95.6 kN, C0 88 kN, Pu 3.75 kN.SKF publishes only the 4,500 r/min limiting speed for this execution, catalogue mass 2100 g. The 3.75 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 95.6/88 kN ratings and 2100 g mass this execution carries about 1.27 kN of C per millimetre of bore. Mass and section check: 2100 g inside the 75×130×41.3 mm outline leaves a 27.5 mm radial section, and the 88 kN static rating is 0.92× the dynamic rating — plan static safety and minimum load against those numbers rather than against sister executions. Speed-ratio note for this exact unit: no thermal reference speed is listed (seal/grease life governs), so the 4,500 r/min limiting value is the single published ceiling. 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 capped speed ceiling is 4,500 r/min — seal drag and grease life govern, which is why SKF publishes no thermal reference speed for A-2Z.
• 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 3215-A-2Z in solvent: the lifetime grease fill cannot be replaced once flushed out.
• 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.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 3215 A-2Z as the double shielded execution; the other order numbers of the 3215 size are different products and may carry different ratings — always quote the full designation when purchasing.
