580 interchange
580 is an inch tapered roller bearing cone. Inch tapered roller bearings are ordered by cone number and cup number. Most makers use the same cone and cup numbers for the same size, but always check the cup number as well. Send us the numbers on your old bearing and we confirm the match before quoting.
Brand names are trademarks of their respective owners. FULI is not affiliated with, authorized by or endorsed by these companies. Part numbers are shown for interchange reference only. FULI dimensions, load ratings and speeds come from the FULI catalog.
580 compared with nearby cone sizes
The 580 cone has a 82.55 mm (3.250 in) bore and a cone width of 36.098 mm. FULI's catalog pairs it with cup 572 (139.992 mm outside diameter, 36.512 mm total width).
The next smaller cone on this site is 6461A, with a 76.2 mm bore (6.35 mm smaller) and cup 6420.
The next larger is 663, with a 82.55 mm bore (0 mm larger) and cup 653.
The metric tapered bearing on this site closest in bore is 32217 (85 × 150 × 38.5 mm). Its sizes differ from the 580 pair, so the two are not interchangeable; it is given only as a size reference.

580 load ratings
580/572 has a dynamic load rating Cr of 176.3 kN and a static rating C0r of 262.6 kN in FULI's catalog. The ratings belong to the cone and cup as a pair; a different cup changes them.
Speed limits and weights for inch cones are not listed in the catalog; ask us and we send them with the quotation.

580 size in inches and millimetres
580 is made to inch sizes. The 82.55 mm bore is 3-1/4 in. The millimetre values in the catalog are conversions of the inch sizes.
| Dimension | Millimetres | Inches |
|---|---|---|
| Cone bore d | 82.55 mm | 3.2500 in |
| Cup outside diameter D (572) | 139.992 mm | 5.5115 in |
| Total width T | 36.512 mm | 1.4375 in |
| Cone width B | 36.098 mm | 1.4212 in |
| Cup width C | 28.575 mm | 1.1250 in |
Converted at 1 in = 25.4 mm and rounded to four decimals.
Mounting 580 (general guidance)
General guidance, not a FULI specification: on a turning shaft the cone is a tight fit on the shaft and the cup a lighter fit in the housing, so the cup can be moved when the bearing pair is adjusted. Inch bearing fits are given as shaft and housing limits in inches in the bearing makers' tables; follow the drawing of your machine.
Tapered roller bearings carry radial load and axial load in one direction, so 580 is normally used as one of a pair, and the end play or preload is set at mounting.
If the outer ring turns and the shaft stands still, as in an idler pulley or a wheel hub, the fits are reversed: the housing gets the interference fit (for example N7 or P7) and the shaft a sliding one (g6 or h6).
Grease for 580
FULI supplies tapered roller bearings rust-protected and normally without grease; grease is packed in when the bearing is mounted. Relubricating 580/572 from the side takes about 25.6 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 139.99 × 36.51.
How FULI supplies 580
580 is supplied as a cone, as a cup or as a complete cone and cup pair, as your order states. Where an order states a requirement for the total width T (36.512 mm for 580/572), each set is checked on a height gauge before packing.
Rings are marked with a brand you are authorised to use, with the FULI brand, or left neutral, as your order states. The box is printed with the model, precision class and brand.
Inquiries that give only one number are the usual cause of a wrong quote, so write both the cone and the cup number, for example 580/572.

FAQ
What size is 580 in mm?
The 580 cone has a 82.55 mm bore (3.250 in). With cup 572 the bearing is 82.55 × 139.992 × 36.512 mm (d × D × T).
What is the difference between 580 and 663?
663 has a 82.55 mm bore against 82.55 mm for 580, and pairs with cup 653 (82.55 × 146.05 × 41.275 mm) instead of 572 (82.55 × 139.992 × 36.512 mm). The two are not interchangeable; order by the numbers on the old cone and cup.
How much grease does 580/572 need?
About 25.6 g each time it is relubricated from the side (0.005 × 139.99 × 36.51). FULI ships it rust-protected without grease, so the first fill is made at mounting.
Which cup goes with the 580 cone?
FULI's catalog pairs the 580 cone with cup 572. Tell us whether you need the cone, the cup or both when you send the inquiry.
Is 580 the same size across brands?
580 is an inch tapered roller bearing cone number. Most makers use the same cone and cup numbers for the same size, but check the cup number too. Send us the numbers on your old bearing and we confirm the match.
