How the 54416-M model number is decoded

The 54400 series order number 54416 M is a SKF double-direction thrust ball bearing for a 65 mm seat, built to ISO 104, with a sphered housing washer paired to a U seat washer, 65×170×128.5 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 trailing M names a solid machined brass window cage centred on the balls rather than on a washer, the catalogue choice when size, speed or interrupted lubrication rules out sheet steel. Envelope 65×170×128.5 mm (2.559×6.693×5.059 in), 52.5 mm radial section, C 307 kN, C0 750 kN, Pu 25 kN. Mounted height H1 140 mm includes the U 416 seat washer; the bearing alone is 128.5 mm high. reference speed 850 r/min (thermal) and limiting speed 1,200 r/min (mechanical), catalogue mass 17500 g. Sizing arithmetic on the 65 mm bore: 307 kN C over the 52.5 mm radial section gives 5.8 kN per section millimetre, and the 128.5 mm stack height is 2.45× that section — proportions typical of a 54400 thrust section. Speed-ratio note for this exact unit: the reference speed is 850 r/min against a 1,200 r/min limiting speed, a reference-to-limit ratio of 0.71. Capacity density: 307 kN C from 17.500 kg of bearing steel gives about 17.5 kN per kilogram; static density is correspondingly 42.9 kN/kg at C0 750 kN. Speed planning separates the two ceilings mechanically: the pressed brass cage and balls tolerate 1,200 r/min while thermal balance under catalogue load sets the 850 r/min reference; at dm ≈ 117.5 mm the corresponding dn is approximately 141k mm·r/min. Track-circle loading: per millimetre of mean track circumference the 307 kN dynamic rating corresponds to roughly 0.83 kN/mm of π·dm track, a useful comparison against the other dimension series of the 65 mm bore. Heavy bidirectional self-aligning note: the two machined brass cage sets and the two sphered housing washer / U seat-washer pairs make this the heaviest standard thrust-ball execution of its bore — check both spherical interfaces for fretting at overhaul and confirm both U washers are the catalogue-matched designations before reassembly. Condition monitoring of 54416 M should sample both sides independently: asymmetric wear between the two 750 kN-rated track pairs reveals unequal duty or one spherical interface that has stopped seating.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• Minimum load factor A 2.3 applies to both load directions, and both brass machined cage sets need lubricant reaching the upper track on a vertical shaft.
• Replacement ordering is THREE numbers: 54416 M plus two pieces of U 416; quoting only the bearing leaves the sphered backs running on bare registers.
• The 307/750 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.
• Order TWO seat washers for 54416 M — the designation U 416 pairs with one side and a second U washer (same number) with the other; the catalogue 140 mm H1 includes both.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 54416 M as the double sphered brass execution; other order numbers of the 54416 size are different products and may carry different ratings or seating geometry — always quote the full designation including the U 416 seat washer when purchasing.
