14139 interchange
14139 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.
14139 compared with nearby cone sizes
The 14139 cone has a 34.976 mm (1.377 in) bore and a cone width of 19.583 mm. FULI's catalog pairs it with cup 14276 (69.012 mm outside diameter, 19.845 mm total width) and cup 14274 (69.012 mm outside diameter, 19.8 mm total width).
The next smaller cone on this site is LM48549, with a 34.925 mm bore (0.05 mm smaller) and cup LM48510.
The next larger is L68149, with a 34.988 mm bore (0.01 mm larger) and cup L68110.
Cup 14276 is also listed with 14125A, 14137A and 14116, so the same housing bore can take a different cone if the shaft size changes.
The metric tapered bearing on this site closest in bore is 32007 (35 × 62 × 18 mm). Its sizes differ from the 14139 pair, so the two are not interchangeable; it is given only as a size reference.

14139 load ratings
14139/14276 has a dynamic load rating Cr of 50.6 kN and a static rating C0r of 61.7 kN and 14139/14274 has a dynamic load rating Cr of 48.4 kN and a static rating C0r of 58.1 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.

14139 size in inches and millimetres
14139 is made to inch sizes. The 34.976 mm bore is 1.3770 in; the nearest common fraction is 1-3/8 in (34.93 mm). The millimetre values in the catalog are conversions of the inch sizes.
| Dimension | Millimetres | Inches |
|---|---|---|
| Cone bore d | 34.976 mm | 1.3770 in |
| Cup outside diameter D (14276) | 69.012 mm | 2.7170 in |
| Total width T | 19.845 mm | 0.7813 in |
| Cone width B | 19.583 mm | 0.7710 in |
| Cup width C | 15.875 mm | 0.6250 in |
Converted at 1 in = 25.4 mm and rounded to four decimals.
Mounting 14139 (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 14139 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 14139
FULI supplies tapered roller bearings rust-protected and normally without grease; grease is packed in when the bearing is mounted. Relubricating 14139/14276 from the side takes about 6.85 g each time by the formula in our grease calculator: 0.005 × D × T = 0.005 × 69.01 × 19.84.
How FULI supplies 14139
14139 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 (19.845 mm for 14139/14276), 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 14139/14276.

FAQ
What size is 14139 in mm?
The 14139 cone has a 34.976 mm bore (1.377 in). With cup 14276 the bearing is 34.976 × 69.012 × 19.845 mm (d × D × T). With cup 14274 it is 69.012 mm outside diameter and 19.8 mm wide.
What is the difference between 14139 and L68149?
L68149 has a 34.988 mm bore against 34.976 mm for 14139, and pairs with cup L68110 (34.988 × 59.131 × 15.875 mm) instead of 14276 (34.976 × 69.012 × 19.845 mm). The two are not interchangeable; order by the numbers on the old cone and cup.
How much grease does 14139/14276 need?
About 6.85 g each time it is relubricated from the side (0.005 × 69.01 × 19.84). FULI ships it rust-protected without grease, so the first fill is made at mounting.
Which cup goes with the 14139 cone?
FULI's catalog pairs the 14139 cone with cups 14276 and 14274. Tell us whether you need the cone, the cup or both when you send the inquiry.
Is 14139 the same size across brands?
14139 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.
