How the 52216 model number is decoded

The 52200 series order number 52216 is a SKF double-direction thrust ball bearing for a 65 mm seat, built to ISO 104, with a flat housing seating surface, 65×115×48 mm boundary dimensions. Inside the unit sit a single central shaft washer with a ground interference bore, two outward-facing loose housing washers and two independent ball-cage assemblies, so axial force is reacted in both directions from one housing recess. bore-coding caveat: on 52/54 double-direction bearings the last two digits are an order-number code, not ×5 millimetres — this size carries a 65 mm bore per the ISO 104 table, and guessing from the code gives the wrong shaft. the suffix-free listing carries the catalogue default: a pressed (stamped sheet-steel) ball-cage assembly, light and quiet, used across the small and medium sizes. Envelope 65×115×48 mm (2.559×4.528×1.89 in), 25.0 mm radial section, C 76.1 kN, C0 208 kN, Pu 7.65 kN. reference speed 2,400 r/min (thermal) and limiting speed 3,400 r/min (mechanical), catalogue mass 1700 g. Light-load floor: Pu = 7.65 kN is the equivalent-load threshold below which the SKF adjusted-life equation credits very long life for 52216; the number is 10 % of the 76.1 kN dynamic rating. Load balance: C0 208 kN against C 76.1 kN gives a 2.73 ratio — thrust ball bearings are chosen on static rating and F_a/C0 far more often than on L10 life, while Pu 7.65 kN enters the adjusted-life check. Section proportions: the 25.0 mm radial section compares with 65 mm of bore (section/bore ≈ 0.38) and the 48 mm height is 1.92× that section — the proportions that identify the 52200 envelope at a glance. Sizing arithmetic on the 65 mm bore: 76.1 kN C over the 25.0 mm radial section gives 3.0 kN per section millimetre, and the 48 mm stack height is 1.92× that section — proportions typical of a 52200 thrust section. Imperial cross-check for procurement drawings: 2.559 in bore, 4.528 in OD, 1.89 in height, and the 1700 g catalogue mass converts to 1.700 kg (60.0 oz). 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 65 mm bore and 48 mm overall height the unit drops into one recess where a mirrored single-direction pair would need two seats; both loose 115 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 0.22): 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 65 mm shaft while both outer housing washers run loose in their registers; both loose washers need positive axial retention on vertical shafts.
• The double-direction 52216 is one central shaft washer with tracks on both faces, two housing washers and two ball-cage assemblies — a single unit locating the 65 mm shaft axially in both directions instead of a mirrored pair.
• Do not replace a 52216 with two single-direction 51-series bearings without re-checking the arrangement: envelope heights, seat details and catalogue ratings differ, even at the same 65×115 mm bore and OD.
• Ordering discipline for 52216: the catalogue page quotes 52216 and its 76.1/208 kN ratings as one exact article; bare-number substitutions from another series or brand need a fresh dimension and rating check, not a like-for-like assumption.
