How the 52202 model number is decoded

52202 is SKF's 10 mm-bore double-direction thrust ball bearing in the 52200 series to the ISO 104 dimension plan, with a flat housing seating surface, measuring 10×32×22 mm. The unit stacks one central shaft washer (ground bore, tight on the shaft), two outward-facing housing washers and two ball-cage assemblies, reacting axial force in both directions. double-direction 52/54 numbering does NOT decode the bore by the usual single-direction ×5 code — read the 10 mm bore from the dimension table; codes recur across the 522/523/524 sections and systematically trail the 51/53 code values. with no cage suffix this is the standard execution with a stamped sheet-steel ball-cage assembly (pressed cage) — the light, quiet and economical cage for small and medium thrust-ball sizes. Envelope 10×32×22 mm (0.394×1.26×0.866 in), 11.0 mm radial section, C 15.9 kN, C0 25 kN, Pu 0.915 kN. reference speed 5,300 r/min (thermal) and limiting speed 7,500 r/min (mechanical), catalogue mass 81 g. Light-load floor: Pu = 0.915 kN is the equivalent-load threshold below which the SKF adjusted-life equation credits very long life for 52202; the number is 6 % of the 15.9 kN dynamic rating. Envelope economics: the 22 mm axial height over a 11.0 mm radial section yields 0.7 kN of dynamic capacity per height millimetre, and the bearing weighs 81 g for 15.9 kN C — about 5 g per rated kN. Speed band width for this size is 2,200 r/min between reference and limiting (1.42× ratio); lubrication, preload and heat removal decide where inside that band 52202 can actually run. Minimum-load arithmetic: with dm ≈ 21.0 mm and factor A 0.0038, Fam ≈ A·(n·dm/1000)² at the 5,300 r/min reference speed is about 47 N for 52202; below that preload the balls skid and smear the tracks. Bore-to-OD planning: OD 32 over bore 10 is a 3.20× step for this size, and the 22 mm height gives a bore/height ratio of 0.45; use these ratios when the housing recess around the 10 mm shaft is the first constraint. Double-direction order-number note: the unit is built around one central shaft washer with a ground bore and tracks on both faces, flanked by two housing washers and two independent ball-cage assemblies; observe the assembly orientation (the two housing washers face outwards) and note that a 52-series unit replaces a mirrored pair of 51-series bearings only after the stack height and seat drawings are re-checked. Life accounting for 52202 is done separately per direction: if duty applies 15.9 kN C predominantly one way, the idle side's skid risk — not the loaded side's L10 — usually sets the relubrication and preload interval.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Torque the cover to leave the catalogue axial freedom, never solid: a clamped double-direction stack cannot float to its thermal position, and at 7,500 r/min even a small thermal thrust preload smears the hottest track.
• Service both cage sets together: replacing only the noisy side while leaving the worn 25 kN opposite track in place reproduces the failure within weeks — inspect both shaft-washer faces and both loose washers at removal.
• Observe the stack order at fitting: shaft washer central, the two housing washers facing outwards with a cage set on each side; the 22 mm total height is not twice a single-direction bearing height, so reuse of old cover dimensions is a trap.
• Do not replace a 52202 with two single-direction 51-series bearings without re-checking the arrangement: envelope heights, seat details and catalogue ratings differ, even at the same 10×32 mm bore and OD.
• The 15.9/25 kN figures belong to 52202 specifically (the double flat pressed steel execution of 52202); suffixed, sphered and counterpart-series order numbers are separate articles, so write the complete designation on the order and the maintenance record.
