How the 3200-A-2Z model number is decoded

3200 A-2Z is the capped double-row angular-contact ball bearing for a 10 mm shaft, 10×30×14 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 10×30×14 mm (0.394×1.181×0.551 in), 10.0 mm radial section height, C 7.61 kN, C0 4.3 kN, Pu 0.183 kN.SKF publishes only the 24,000 r/min limiting speed for this execution, catalogue mass 51 g. Load balance: C0 4.3 kN against C 7.61 kN gives a 0.57 ratio, typical of a steep-angle axial-oriented design; Pu 0.183 kN enters the SKF adjusted-life equation rather than the basic rating life. The 0.183 kN fatigue load limit is the equivalent-load floor for long-life adjustment; with 7.61/4.3 kN ratings and 51 g mass this execution carries about 0.76 kN of C per millimetre of bore. Speed-ratio note for this exact unit: no thermal reference speed is listed (seal/grease life governs), so the 24,000 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 shields/seals do not make the bearing waterproof under immersion or pressure washing; select external sealing for wet or wash-down duty.
• Fit and fillet rules are unchanged from the open double-row 3200: j5 on a 10 mm rotating shaft, radii clearing the chamfer.
• Never wash 3200-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 3200 A-2Z as the double shielded execution; the other order numbers of the 3200 size are different products and may carry different ratings — always quote the full designation when purchasing.
