The 3519/710 (10979/710) is a 710×950×240mm double row tapered roller bearing weighing 445kg. Both designations refer to the identical bearing — 3519/710 is the GB/ISO standard; 10979/710 is the alternative cross-reference.
Available in three configurations: standard open (3519/710), duplex face-to-face matched pair (3519/710J2/DF), and extended inner ring with specific cage (3519/710X-N11CA).
Internal construction: double cup + two cones + optional spacer — separable, field-maintainable without special tools.
Designation | Configuration | Typical Use |
3519/710 | Standard open | General heavy industry |
10979/710 | Cross-reference — identical bearing | — |
3519/710J2/DF | Duplex matched pair, face-to-face (DF) | Bidirectional axial stiffness; rolling mill roll necks; precision gearbox shafts |
3519/710X-N11CA | Extended inner ring (X) + specific cage (N11CA) | Wider shaft support; specific OEM housing designs |
Confirm suffix with your equipment drawing or OEM manual before ordering.
Industry | Typical Use | Selection Reason |
Steel & Rolling Mills | Work/backup roll necks, pinion stands | High combined load; shock & vibration resistance |
Mining & Minerals | Crusher mainshafts, mill trunnions, conveyor drives | Contaminated environment; impact loads; misalignment |
Oil & Gas | Rotary table assemblies, top drive systems, drawworks | Impact resistance; high static load capacity |
Heavy Industrial Gearboxes | Large output / intermediate shafts | Bidirectional axial load; high rigidity |
Hoisting & Lifting | Crane slewing rings, winch drums | Combined load; long service life |
Tunnelling Machinery | TBM main bearings, cutter head drives | Severe misalignment; contamination resistance |

Q: 3519/710 vs 10979/710 — what's the difference?
Same bearing. 3519/710 = GB/ISO designation. 10979/710 = alternative cross-reference.
Q: What is the 3519/710J2/DF configuration?
Duplex matched pair, face-to-face (DF) arrangement — two bearings ground and matched at the factory to a defined internal preload. Used where precise axial positioning and high bidirectional axial stiffness are required: rolling mill roll necks, precision gearbox shafts.
Q: What is the 3519/710X-N11CA configuration?
Extended inner ring (X suffix) with a specific cage designation (N11CA) — for applications requiring wider shaft support or specific OEM housing designs. Confirm with your equipment drawing.
Q: How does the 3519/710 compare to the 3519/670?
Same 240mm width. Bore: +40mm. OD: +50mm. Weight: +29kg. Specified by shaft diameter — if your shaft is 670mm, see the 3519/670.
Q: How does the 3519/710 compare to the 3519/750?
The 3519/750 adds +40mm bore, +50mm OD, +24mm width, +54kg. If your shaft is 750mm, see the 3519/750.
Q: What precision grade is required?
P0 / ABEC-1 — gearboxes, mining, hoisting, oil field (standard)
P6 / ABEC-3 — speed reducers, paper machinery
P5 / ABEC-5 — rolling mill finishing stands, precision gearboxes
P4 / P2 — high-precision applications; confirm with OEM equipment data
Q: Lubrication — rolling mill vs mining / oil field?
Rolling mills: open configuration, circulating oil ISO VG 220–460. Mining / oil field: EP-additive grease NLGI Grade 2–3. Confirm with OEM equipment manual.
Q: What documentation is available?
GCr15 / AISI 52100 material certificates, dimensional inspection reports, load rating test reports, packing lists, commercial invoices, certificates of origin. ISO9001 / IATF16949 certified supply chain. SGS / BV / TÜV third-party inspection supported.
Q: MOQ and lead time?
MOQ: 1 piece for stock items. Lead time: 5–7 business days (stock); confirmed at order for made-to-order. FOB Qingdao / CIF / EXW. Full wooden crating and heavy-lift documentation included at 445kg unit weight.
