How the 54207 model number is decoded

54207 is SKF's 30 mm-bore double-direction thrust ball bearing in the 54200 series to the ISO 104 dimension plan, with a sphered housing washer paired to a U seat washer, measuring 30×62×37.8 mm U 207 seat washer companion included in the mounted H1 dimension. 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 30 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 30×62×37.8 mm (1.181×2.441×1.488 in), 16.0 mm radial section, C 35.1 kN, C0 73.5 kN, Pu 2.7 kN. Mounted height H1 42 mm includes the U 207 seat washer; the bearing alone is 37.8 mm high. reference speed 2,800 r/min (thermal) and limiting speed 4,000 r/min (mechanical), catalogue mass 530 g. Bore-to-OD planning: OD 62 over bore 30 is a 2.07× step for this size, and the 37.8 mm height gives a bore/height ratio of 0.79; use these ratios when the housing recess around the 30 mm shaft is the first constraint. Capacity density: 35.1 kN C from 0.530 kg of bearing steel gives about 66.2 kN per kilogram; static density is correspondingly 138.7 kN/kg at C0 73.5 kN. Load balance: C0 73.5 kN against C 35.1 kN gives a 2.09 ratio — thrust ball bearings are chosen on static rating and F_a/C0 far more often than on L10 life, while Pu 2.7 kN enters the adjusted-life check. Light-load floor: Pu = 2.7 kN is the equivalent-load threshold below which the SKF adjusted-life equation credits very long life for 54207; the number is 8 % of the 35.1 kN dynamic rating. Static-first selection data: 73.5 kN C0 spread across the 37.8 mm stack gives 1.9 kN of static rating per height millimetre, and the 530 g mass/C0 ratio is about 7 g per static kN — crane-hook and screw positions are normally sized on these two figures. Bidirectional self-aligning note: TWO U seat washers are required for this order number, one behind each housing washer, and the catalogue H1 height includes them on both sides of the stack; the spherical interfaces accept initial misalignment in either load direction but are not pivots for continuous oscillation. At 30×62×37.8 mm the bearing carries C0 73.5 kN bidirectionally, but the two U interfaces share that load only if each is free to seat; torque the covers so the 4.2 mm-per-side washer steps are not pre-clamped.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Assembly is a five-component stack (central shaft washer, two cage sets, two sphered housing washers) plus the two U seat washers in the housing registers; dry-build the arrangement by hand first to confirm both sides swivel freely.
• Minimum load factor A 0.028 applies to both load directions, and both brass pressed cage sets need lubricant reaching the upper track on a vertical shaft.
• Replacement ordering is THREE numbers: 54207 plus two pieces of U 207; quoting only the bearing leaves the sphered backs running on bare registers.
• The 35.1/73.5 kN ratings assume the spherical contacts are free to find their seat — a painted-over or shimmed U washer fixes the angle and turns the self-aligning bearing into an edge-loaded one.
• Ordering discipline for 54207: the catalogue page quotes 54207 plus U 207 and its 35.1/73.5 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.
