The 3519/750 (10979/750) is a 750×1000×264mm double row tapered roller bearing weighing 499kg. Both designations refer to the identical bearing — 3519/750 is the GB/ISO standard; 10979/750 is the alternative cross-reference.
Steps up from the 3519/710 (445kg) by +40mm bore, +50mm OD, +24mm width, +54kg — the mid large-bore tier of the 3519 series, between the 3519/710 and 3519/800. $CITE_1 $CITE_3
Internal construction: double cup + two cones + optional spacer — separable, field-maintainable without special tools.
Industry | Typical Use | Selection Reason |
Steel & Rolling Mills | Work/backup roll necks, pinion stands | High combined load; shock & vibration resistance |
Mining & Minerals | Crusher mainshafts, SAG/ball mill trunnions | Contaminated environment; impact loads; misalignment |
Paper & Pulp Machinery | Large press roll necks, dryer / calendar rolls | High radial load; continuous operation; moisture resistance |
Heavy Industrial Gearboxes | Large output / intermediate shafts | Bidirectional axial load; high rigidity |
Hoisting & Lifting | Crane slewing rings, winch drums, drawworks | Combined load; high static capacity; cyclic reliability |
Speed Reducers | Large planetary and parallel-shaft reducers | Precision alignment; high load density; low vibration |

Q: 3519/750 vs 10979/750 — what's the difference?
Same bearing. 3519/750 = GB/ISO designation. 10979/750 = alternative cross-reference.
Q: How does the 3519/750 compare to the 3519/710?
+40mm bore, +50mm OD, +24mm width, +54kg. Specified by shaft diameter — if your shaft is 710mm, see the 3519/710.
Q: How does the 3519/750 compare to the 3519/800?
The 3519/800 adds +50mm bore, +60mm OD, +6mm width, +105kg. If your shaft is 800mm, see the 3519/800.
Q: What precision grade is required?
P0 / ABEC-1 — gearboxes, mining, hoisting (standard)
P6 / ABEC-3 — paper machinery, speed reducers
P5 / ABEC-5 — rolling mill finishing stands, precision gearboxes
P4 / P2 — high-precision applications; confirm with OEM equipment data
Q: Sealing and lubrication — rolling mill vs mining?
Rolling mills: open configuration, circulating oil ISO VG 220–460. Mining / outdoor: ZZ or 2RS with EP-additive grease NLGI Grade 2–3. Confirm with OEM equipment manual.
Q: Recommended clearance for crusher / high-temperature applications?
C3 or C4 — accommodates thermal expansion and prevents preload under impact. C0 for standard gearbox service at ambient temperature.
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 499kg unit weight.
Q: OEM / private label available?
Yes — custom box artwork, laser-engraved logo on bearing ring, fully branded packaging. All IP rights belong to you. MOQ and pricing on request.
