How the 52214 model number is decoded

52214 is SKF's 55 mm-bore double-direction thrust ball bearing in the 52200 series to the ISO 104 dimension plan, with a flat housing seating surface, measuring 55×105×47 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 55 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 55×105×47 mm (2.165×4.134×1.85 in), 25.0 mm radial section, C 62.4 kN, C0 160 kN, Pu 5.85 kN. reference speed 1,900 r/min (thermal) and limiting speed 2,600 r/min (mechanical), catalogue mass 1500 g. Light-load floor: Pu = 5.85 kN is the equivalent-load threshold below which the SKF adjusted-life equation credits very long life for 52214; the number is 9 % of the 62.4 kN dynamic rating. Stack/annulus proportions: the 47 mm axial stack over the 6,283 mm² washer annulus gives 7.48 mm of height per annular square millimetre ×10⁻³, and at 1500 g the bearing holds about 106.7 kN of C0 per kilogram. Section proportions: the 25.0 mm radial section compares with 55 mm of bore (section/bore ≈ 0.45) and the 47 mm height is 1.88× that section — the proportions that identify the 52200 envelope at a glance. Speed band width for this size is 700 r/min between reference and limiting (1.37× ratio); lubrication, preload and heat removal decide where inside that band 52214 can actually run. Envelope economics: the 47 mm axial height over a 25.0 mm radial section yields 1.3 kN of dynamic capacity per height millimetre, and the bearing weighs 1500 g for 62.4 kN C — about 24 g per rated kN. 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. At 55 mm bore and 47 mm overall height the unit drops into one recess where a mirrored single-direction pair would need two seats; both loose 105 mm housing washers must remain free to slide during thermal movement.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Each direction independently needs the minimum axial load (factor A 0.16): the side that is momentarily unloaded during slow reversal skids first, so arrange preload or symmetry rather than assuming the loaded side drives the idle side.
• The central shaft washer takes the interference fit on the 55 mm shaft while both outer housing washers run loose in their registers; both loose washers need positive axial retention on vertical shafts.
• Service both cage sets together: replacing only the noisy side while leaving the worn 160 kN opposite track in place reproduces the failure within weeks — inspect both shaft-washer faces and both loose washers at removal.
• Do not replace a 52214 with two single-direction 51-series bearings without re-checking the arrangement: envelope heights, seat details and catalogue ratings differ, even at the same 55×105 mm bore and OD.
• The 62.4/160 kN figures belong to 52214 specifically (the double flat pressed steel execution of 52214); suffixed, sphered and counterpart-series order numbers are separate articles, so write the complete designation on the order and the maintenance record.
