The 3519/530 is a 530mm bore, ~190kg large-format bearing. Lead time, pricing, and availability depend on precision grade and clearance specification. Contact our technical team before ordering to confirm exact dimensional requirements, preload specification, and delivery schedule.
The 3519/530 is available in both TDO (Tandem Double Outer) and TDI (Tandem Double Inner) configurations:
Configuration | Structure | Axial Load Direction |
TDO | Double cup · 2 cones · 1 spacer ring · double row rollers · 2 pressed cages | Handles axial loads from both directions; outer ring (cup) is single unit |
TDI | Double cone · 2 cups · spacer ring | Handles axial loads from both directions; inner ring (cone) is single unit |
Spacer rings available with or without lubricant grooves and holes
Both configurations support use as locating or non-locating bearings
Mounting holes on both inner and outer rings for easy installation
Specify TDO or TDI at time of order. Default supply is TDO unless otherwise stated. Contact our technical team to confirm the correct configuration for your application.
The 3519/530 (10979/530) is a 530×710×190mm double row tapered roller bearing for heavy industrial applications — rolling mills, mining equipment, large gearboxes, and heavy-duty axle assemblies.
Double-row tapered roller geometry simultaneously handles high radial loads (equipment weight / process forces) and bidirectional axial loads (thrust forces in both directions) — the defining advantage of this configuration over single-row or ball bearing alternatives. The large 530mm bore and ~190kg mass place this bearing in the heavy industrial / metallurgical category.
Available in P0 through P2 precision grades and C0 through C5 clearance classes — specify both parameters at time of order.

SKF / FAG / Timken / KOYO | Contact us — confirm dimensional equivalence before ordering |
Due to the large bore and GOST-specific geometry, international brand cross-references require technical verification. Provide your application details and dimensional drawing for confirmed equivalents.
Industry | Application |
Steel / Metallurgy | Rolling mill roll necks, continuous casting equipment |
Mining | Crusher main shafts, conveyor drive heads, mill pinion shafts |
Heavy Machinery | Large gearbox output shafts, industrial reducers |
Power Generation | Turbine support bearings, large generator shafts |
Marine / Port Equipment | Crane slewing rings, large winch drums |
Advantage | Detail |
High radial load capacity | Line contact between tapered rollers and raceways — superior to ball bearings at large bore sizes |
Bidirectional axial load | Double-row arrangement handles thrust in both directions simultaneously |
Adjustable preload | Precise preload setting optimises stiffness and running accuracy for the application |
High rigidity | Critical for rolling mill and machine tool applications requiring minimal shaft deflection |
Separable design | Cone and cup assemblies can be replaced independently — reduces maintenance cost |
Q: 3519/530 vs 10979/530 — what's the difference?
Same bearing — two GOST designation systems. 3519/530 = GOST series designation. 10979/530 = alternative GOST numbering for the same 530×710×190mm double row tapered roller bearing. Always confirm dimensions against your application drawing.
Q: What precision grade should I specify?
P0 (standard) suits most heavy industrial applications. P5 / P4 / P2 are available for applications requiring higher running accuracy (e.g. precision rolling mills, machine tool spindles). Specify at time of order — precision grade affects lead time and pricing.
Q: What clearance class should I specify?
C0 (standard) for most applications. C3 / C4 for applications with significant thermal expansion (e.g. hot rolling mills, high-speed equipment). Consult our technical team if unsure — incorrect clearance on a 530mm bearing causes significant performance and service life issues.
Q: Does this bearing require preload adjustment during installation?
Yes. As a double row tapered roller bearing, correct preload / clearance setting during installation is critical. Follow the OEM equipment manual or contact our technical team for installation guidance specific to your application.
Q: What is the lead time for 3519/530?
Large-bore bearings (530mm+) are typically made-to-order. Lead time varies by precision grade and clearance specification. Contact us with your full requirements for a confirmed delivery schedule.
Q: What documentation is available?
Dimensional inspection reports, GCr15 / AISI 52100 material certificates, hardness test reports, packing lists, commercial invoices, certificates of origin. SGS / BV / TÜV third-party inspection supported.
Q: OEM / private label available?
Yes — custom box artwork, laser-engraved part number and logo on bearing ring, fully branded packaging. All IP rights belong to you. MOQ and pricing on request.
Q: Do you supply other large-bore GOST tapered roller bearings?
Yes — Nexans Bearings maintains a full range of GOST large-bore tapered roller bearings for mining, metallurgy, and heavy industry. Contact us with your part numbers or dimensional requirements.
