How the 51192-F model number is decoded

51192 F is SKF's 460 mm-bore single-direction thrust ball bearing in the 51100 series to the ISO 104 dimension plan, with a flat housing seating surface, measuring 460×560×80 mm. The separable set comprises a shaft washer (ground bore, tight fit on the shaft), a loose-bore housing washer and one ball-cage assembly, reacting axial force in one direction and carrying no radial load. in the 51xxx designation the first 1 marks a single-direction bearing with a flat housing seating surface; the third digit 1–4 grades the dimension series from the light 511 section through the heavy 514 section. the final two digits 92 encode the bore as 460 mm (code 92 × 5), the standard SKF bore-code rule shared with radial bearings. suffix F identifies a machined steel cage, ball-centred: fitted to the largest sizes of the assortment where the ball complement and centrifugal forces exceed what the stamped sheet-steel execution can guide. Envelope 460×560×80 mm (18.11×22.047×3.15 in), 50.0 mm radial section, C 527 kN, C0 3250 kN, Pu 54 kN. reference speed 600 r/min (thermal) and limiting speed 800 r/min (mechanical), catalogue mass 43500 g. Section proportions: the 50.0 mm radial section compares with 460 mm of bore (section/bore ≈ 0.11) and the 80 mm height is 1.60× that section — the proportions that identify the 51100 envelope at a glance. Imperial cross-check for procurement drawings: 18.11 in bore, 22.047 in OD, 3.15 in height, and the 43500 g catalogue mass converts to 43.500 kg (1534.4 oz). Static-first selection data: 3250 kN C0 spread across the 80 mm stack gives 40.6 kN of static rating per height millimetre, and the 43500 g mass/C0 ratio is about 13 g per static kN — crane-hook and screw positions are normally sized on these two figures. Preload at the mechanical ceiling: repeating Fam ≈ A·(n·dm/1000)² with factor A 55 at the 800 r/min limiting speed raises the required axial preload to about 9155.5 kN; the reference-speed value 5150.0 kN is the thermal design point. Selection figures for 51192 F: the C0/C ratio is 6.17, Pu 54 kN is about 10 % of C, and the catalogue mass works out to roughly 95 g per millimetre of bore; the printed minimum-load factor is A 55. Large-size execution note: the F machined steel cage exists because the ball complement and pitch diameter of the biggest 512-series sizes are beyond pressed-cage guidance; the steel cage is machined from solid, ball-centred, and its heavier mass must be supported by genuine oil or grease flow at start-up — never mount an F bearing dry for a trial rotation. The F execution appears only at the 460 mm top end of the range: the 560 mm OD ball complement is large enough that cage centrifugal forces dictate a machined guide, which is also why the 3250 kN C0 figure dominates selection of this order number.

Typical equipment & failure modes

Selection pitfalls — read before you substitute

• A 51-series bearing reacts thrust in one direction only — reversing positions need a mirrored single-direction pair or a 52-series double-direction unit; fitting a single 51192 against two-way load lifts the loose washer off its raceway.
• The three components are separable and interchangeable within the ISO 104 size, but keep this bearing's parts together in service and never combine washers from different manufacturers or a worn washer with a new ball set.
• The third digit grades the section: 511 light, then 512, 513 and 514 progressively taller and heavier at the same bore — select from 527/3250 kN and the available 560 mm OD, never substitute a lighter series for a heavier one without rechecking C and C0.
• Identify the washers before fitting: the shaft washer has the ground, smaller bore and takes an interference fit on the 460 mm shaft, while the housing washer bore is larger and runs loose; swapping them locks the ball set and burns the tracks.
• Catalogue ratings are SKF PUB BU/P1 17000 figures for 51192 F as the single flat machined steel execution; other order numbers of the 51192 size are different products and may carry different ratings or seating geometry — always quote the full designation when purchasing.
