How the 53207 model number is decoded

The 53200 series order number 53207 is a SKF single-direction thrust ball bearing for a 35 mm seat, built to ISO 104, with a sphered housing washer paired to a U seat washer, 35×62×19.9 mm boundary dimensions. Three separable parts make the set: the tight-bore shaft washer that locates on the shaft, the loose-bore housing washer in its register, and the ball-cage assembly; load is purely axial and acts in one direction. the 3 in 53xxx replaces the flat-seat 1: it still denotes one load direction, but the housing washer is sphered for pairing with a U seat washer, and the following digit 2–4 ranks the section. bore code 07 decodes to 35 mm (code 07 × 5) under the same 00/01/02/03-exception, ×5 rule SKF uses across its coded bearing ranges. 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 35×62×19.9 mm (1.378×2.441×0.783 in), 13.5 mm radial section, C 35.1 kN, C0 73.5 kN, Pu 2.7 kN. Mounted height H1 22 mm includes the U 207 seat washer; the bearing alone is 19.9 mm high. reference speed 4,000 r/min (thermal) and limiting speed 5,600 r/min (mechanical), catalogue mass 280 g. Pitch-diameter arithmetic: dm = (35+62)/2 = 48.5 mm; at the 5,600 r/min limiting speed that corresponds to roughly 272k mm·r/min, the figure used when comparing cage speed demand across the thrust-ball series. Envelope economics: the 19.9 mm axial height over a 13.5 mm radial section yields 1.8 kN of dynamic capacity per height millimetre, and the bearing weighs 280 g for 35.1 kN C — about 8 g per rated kN. Sizing arithmetic on the 35 mm bore: 35.1 kN C over the 13.5 mm radial section gives 2.6 kN per section millimetre, and the 19.9 mm stack height is 1.47× that section — proportions typical of a 53200 thrust section. Mass and section check: 280 g inside the 35×62×19.9 mm outline leaves a 13.5 mm radial section, and the 73.5 kN static rating is 2.09× the dynamic rating — plan static safety and minimum preload against those figures. Bore-to-OD planning: OD 62 over bore 35 is a 1.77× step for this size, and the 19.9 mm height gives a bore/height ratio of 1.76; use these ratios when the housing recess around the 35 mm shaft is the first constraint. Sphered-seating order-number note: the convex back face of the housing washer is finish-ground spherical and is delivered to mate with the separately ordered U seat washer, which presents a flat face to the housing and a concave face to the washer; together they accommodate initial static misalignment, but the pair must be kept clean, greased at the spherical interface and never replaced by a washer-on-flat-steel makeshift. Procurement reminder for this specific page: 53207 and U 207 are two order numbers shipping as two articles; the installed 22 mm H1 rather than 19.9 mm H is the dimension the housing drawing must carry.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• The shaft washer remains the tight, ground-bore component on the 35 mm shaft; the sphered part is the HOUSING washer, and the U seat washer is the loose flat-backed part — the fitting order is shaft washer and cage set first, then housing washer and U 207 into the register.
• Minimum axial load still applies with factor A 0.028: a self-aligning seat does not prevent ball skidding, so provide spring preload or sufficient rotor weight at light load and speed.
• The sphered housing washer of 53207 MUST run against the U 207 seat washer, a separate order number; mounted bare on a flat register, the convex back makes point contact that gouges the housing under load.
• Keep the sphered interface clean and lightly greased: scale, paint or grit between the washer back and U 207 locks the aligning function and frets under load; re-grease the contact at every overhaul.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 53207 as the single sphered pressed steel execution; other order numbers of the 53207 size are different products and may carry different ratings or seating geometry — always quote the full designation including the U 207 seat washer when purchasing.
