How the 54316 model number is decoded

The 54300 series order number 54316 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, 65×140×86.1 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 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 65×140×86.1 mm (2.559×5.512×3.39 in), 37.5 mm radial section, C 159 kN, C0 390 kN, Pu 13.7 kN. Mounted height H1 95 mm includes the U 316 seat washer; the bearing alone is 86.1 mm high. reference speed 1,300 r/min (thermal) and limiting speed 1,800 r/min (mechanical), catalogue mass 5550 g. Track-circle loading: per millimetre of mean track circumference the 159 kN dynamic rating corresponds to roughly 0.49 kN/mm of π·dm track, a useful comparison against the other dimension series of the 65 mm bore. Speed-ratio note for this exact unit: the reference speed is 1,300 r/min against a 1,800 r/min limiting speed, a reference-to-limit ratio of 0.72. Static-first selection data: 390 kN C0 spread across the 86.1 mm stack gives 4.5 kN of static rating per height millimetre, and the 5550 g mass/C0 ratio is about 14 g per static kN — crane-hook and screw positions are normally sized on these two figures. Rating split for documentation: dynamic 159 kN (L10 life), static 390 kN (safety factor s0), fatigue limit 13.7 kN (adjusted life) — three different uses of three different numbers for 54316, none interchangeable with another. Preload at the mechanical ceiling: repeating Fam ≈ A·(n·dm/1000)² with factor A 0.79 at the 1,800 r/min limiting speed raises the required axial preload to about 26.9 kN; the reference-speed value 14.0 kN is the thermal design point. 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. Bill of materials for this page is 54316 plus TWO × U 316; the 95 mm H1 stack sits in a housing whose two register faces should be machined in one clamping to keep both spherical axes coincident.

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 0.79 applies to both load directions, and both brass pressed cage sets need lubricant reaching the upper track on a vertical shaft.
• The 159/390 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.
• Replacement ordering is THREE numbers: 54316 plus two pieces of U 316; quoting only the bearing leaves the sphered backs running on bare registers.
• Ordering discipline for 54316: the catalogue page quotes 54316 plus U 316 and its 159/390 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.
