How the 52213 model number is decoded
The 52200 series order number 52213 is a SKF double-direction thrust ball bearing for a 55 mm seat, built to ISO 104, with a flat housing seating surface, 55×100×47 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 55 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 55×100×47 mm (2.165×3.937×1.85 in), 22.5 mm radial section, C 60.5 kN, C0 150 kN, Pu 5.5 kN. reference speed 2,000 r/min (thermal) and limiting speed 2,800 r/min (mechanical), catalogue mass 1350 g. Speed band width for this size is 800 r/min between reference and limiting (1.40× ratio); lubrication, preload and heat removal decide where inside that band 52213 can actually run. Speed planning separates the two ceilings mechanically: the pressed cage and balls tolerate 2,800 r/min while thermal balance under catalogue load sets the 2,000 r/min reference; at dm ≈ 77.5 mm the corresponding dn is approximately 217k mm·r/min. Sizing arithmetic on the 55 mm bore: 60.5 kN C over the 22.5 mm radial section gives 2.7 kN per section millimetre, and the 47 mm stack height is 2.09× that section — proportions typical of a 52200 thrust section. Capacity density: 60.5 kN C from 1.350 kg of bearing steel gives about 44.8 kN per kilogram; static density is correspondingly 111.1 kN/kg at C0 150 kN. Section proportions: the 22.5 mm radial section compares with 55 mm of bore (section/bore ≈ 0.41) and the 47 mm height is 2.09× that section — the proportions that identify the 52200 envelope at a glance. 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 52213 is done separately per direction: if duty applies 60.5 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
Common applications
- steering and reversing linkages
- machine-tool lead screws and selector shafts
- elevator machinery thrust positions
Known failure patterns
- one-side track spalling when reversing duty dwells predominantly in one direction and only one cage set accumulates cycles
- cover-induced thrust preload when the end cover is torqued solid instead of leaving the catalogue axial freedom
- unbalanced loading of the two cage sets when one load direction dominates service life and the idle set skids
- rolling-contact fatigue spalling after the L10 life at the actual thrust load is exceeded
- electrical discharge pitting when the shaft current passes through the ball contacts instead of a grounding brush
Selection pitfalls — read before you substitute
- Observe the stack order at fitting: shaft washer central, the two housing washers facing outwards with a cage set on each side; the 47 mm total height is not twice a single-direction bearing height, so reuse of old cover dimensions is a trap.
- The double-direction 52213 is one central shaft washer with tracks on both faces, two housing washers and two ball-cage assemblies — a single unit locating the 55 mm shaft axially in both directions instead of a mirrored pair.
- Each direction independently needs the minimum axial load (factor A 0.14): 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.
- Torque the cover to leave the catalogue axial freedom, never solid: a clamped double-direction stack cannot float to its thermal position, and at 2,800 r/min even a small thermal thrust preload smears the hottest track.
- Catalogue ratings are SKF PUB BU/P1 17000 figures for 52213 as the double flat pressed steel execution; other order numbers of the 52213 size are different products and may carry different ratings or seating geometry — always quote the full designation when purchasing.
Frequently asked questions
What are the dimensions and catalogue data of 52213?
Boundary dimensions to ISO 104: bore 55 mm, OD 100 mm, height 47 mm; weight 1350 g. Load figures from SKF 17000: dynamic 60.5 kN, static 150 kN, fatigue limit 5.5 kN; reference speed 2,000 r/min (thermal) and limiting speed 2,800 r/min (mechanical).
What does the designation 52213 mean?
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 55 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. 5 = thrust ball bearing, 2 = double direction with flat seating surfaces.
Can it replace two single-direction 51-series bearings?
It replaces a mirrored pair functionally — one fit, one housing bore, factory-matched geometry — but its 47 mm height is not twice the single-bearing height and seat details differ, so the housing and cover must be re-drawn rather than swapped in place.
How is a vertical double-direction 52213 lubricated and retained?
Use an oil bath reaching the lower track plus a feed or oil level that serves the upper cage set, or a coherent heavy-base grease; positively retain both loose housing washers because gravity loads the upper stack differently at standstill.
