How the 52215 model number is decoded
52215 is SKF's 60 mm-bore double-direction thrust ball bearing in the 52200 series to the ISO 104 dimension plan, with a flat housing seating surface, measuring 60×110×47 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 60 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 60×110×47 mm (2.362×4.331×1.85 in), 25.0 mm radial section, C 63.7 kN, C0 170 kN, Pu 6.2 kN. reference speed 1,900 r/min (thermal) and limiting speed 2,600 r/min (mechanical), catalogue mass 1550 g. Pitch-diameter arithmetic: dm = (60+110)/2 = 85.0 mm; at the 2,600 r/min limiting speed that corresponds to roughly 221k mm·r/min, the figure used when comparing cage speed demand across the thrust-ball series. Track-circle loading: per millimetre of mean track circumference the 63.7 kN dynamic rating corresponds to roughly 0.24 kN/mm of π·dm track, a useful comparison against the other dimension series of the 60 mm bore. 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 52215 can actually run. Light-load floor: Pu = 6.2 kN is the equivalent-load threshold below which the SKF adjusted-life equation credits very long life for 52215; the number is 10 % of the 63.7 kN dynamic rating. Speed planning separates the two ceilings mechanically: the pressed cage and balls tolerate 2,600 r/min while thermal balance under catalogue load sets the 1,900 r/min reference; at dm ≈ 85.0 mm the corresponding dn is approximately 221k mm·r/min. 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 52215 is done separately per direction: if duty applies 63.7 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
- crane travel and slewing drives
- heavy reversing gearbox shafts
- large lead-screw and press adjustment
Known failure patterns
- track-edge spalling after the shaft washer seat is machined out of square and both rows share the tilt
- differential wear when one cage set loses lubrication first on a vertical mounting
- unbalanced loading of the two cage sets when one load direction dominates service life and the idle set skids
- electrical discharge pitting when the shaft current passes through the ball contacts instead of a grounding brush
- fretting corrosion on the shaft-washer ground bore after a loose rotating fit
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 52215 is one central shaft washer with tracks on both faces, two housing washers and two ball-cage assemblies — a single unit locating the 60 mm shaft axially in both directions instead of a mirrored pair.
- Where shaft and housing cannot be kept square, the sphered 54-series execution of the same bore with two U seat washers is the self-aligning counterpart; the flat 52200 unit has no alignment capacity.
- Torque the cover to leave the catalogue axial freedom, never solid: a clamped double-direction stack cannot float to its thermal position, and at 2,600 r/min even a small thermal thrust preload smears the hottest track.
- Catalogue ratings are SKF PUB BU/P1 17000 figures for 52215 as the double flat pressed steel execution; other order numbers of the 52215 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 52215?
52215 measures 60 mm bore × 110 mm OD × 47 mm bearing height (2.362 × 4.331 × 1.85 in), mass about 1550 g. SKF 17000 ratings: C 63.7 kN, C0 170 kN, Pu 6.2 kN, reference speed 1,900 r/min (thermal) and limiting speed 2,600 r/min (mechanical).
What does the designation 52215 mean?
double-direction 52/54 numbering does NOT decode the bore by the usual single-direction ×5 code — read the 60 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. 5 = thrust ball bearing, 2 = double direction with flat seating surfaces.
How is the double-direction 52215 constructed?
One central shaft washer with tracks on both faces and a ground bore, two housing washers facing outwards and two independent ball-cage assemblies — all supplied as one 60×110×47 mm unit locating the shaft axially in both directions.
When should I choose 52-series flat instead of 54-series sphered?
Choose the flat 52-series when the housing register can be machined square to the shaft; choose the 54-series with two U seat washers when initial misalignment has to be accommodated on fabricated or less rigid structures.
