Product Description
The 3510/600 (also referenced as 971/600) is an extreme heavy-duty double row tapered roller bearing with dimensions of 600×870×270mm — one of the largest-format tapered roller bearings in industrial use. At 500kg, with a dynamic load rating (Cr) of 41,000N and a static load rating (Cor) of 51,000N, this bearing is engineered to operate reliably under conditions that would destroy conventional bearings.
Double row tapered roller bearings of this class are specifically designed for extremely severe applications — supporting high combined radial and axial loads, tolerating severe shaft misalignment, resisting contaminated environments, and absorbing heavy shock and vibration loads. These characteristics make the 3510/600 the preferred bearing solution for the most demanding sectors: mining, metallurgy, steel rolling mills, heavy gearboxes, and large industrial machinery.
Manufactured from GCr15 / 52100 chrome steel to ABEC and DIN620 precision standards, and supplied factory-direct by NEXANS Bearing from Liaocheng, Shandong, the 3510/600 delivers the industry's highest load ratings in its size class — with full OEM customization available for global industrial buyers.

✅ Extreme Combined Load Capacity — Double row tapered geometry simultaneously handles massive radial and bidirectional axial (thrust) loads — the defining requirement for heavy mining shafts, rolling mill roll necks, and large industrial gearbox assemblies
✅ Severe Misalignment Tolerance — Engineered to maintain full performance under significant shaft misalignment conditions, reducing sensitivity to installation errors and structural deflection in heavy machinery frames
✅ Shock & Vibration Resistance — Purpose-built to absorb heavy impact loads and continuous vibration — critical for mining crushers, tunneling machines, and heavy-duty industrial drives where shock loading is constant
✅ Contamination Resistance — Available with sealed or shielded configurations to protect against the extreme contamination levels found in mining, metallurgy, and heavy construction environments
✅ 500kg Heavy-Format Construction — The 600×870×270mm dimensions and 500kg weight confirm this as an ultra-large industrial bearing, delivering the structural mass and rolling element volume needed for extreme load applications
✅ Multiple Precision & Clearance Grades — Available in ABEC 1 through 9 and DIN620 P0 through P2 precision grades, with clearance grades C0 through C5 — enabling precise specification matching for diverse heavy industrial applications
✅ GCr15 Chrome Steel Construction — Manufactured from high-grade GCr15 / AISI 52100 chrome steel for exceptional hardness, wear resistance, and rolling contact fatigue life under sustained extreme loads

Q1: What industries and machines use the 3510/600 double row tapered roller bearing?
The 3510/600 is primarily used in extreme heavy-duty industrial applications including large mining crushers, grinding mills, steel rolling mill roll necks, heavy industrial gearboxes, petroleum drilling equipment, and large-scale metallurgical machinery. Its 600mm bore, 500kg weight, and combined load ratings make it one of the largest and most capable tapered roller bearings in industrial use — specifically designed for applications where standard bearings cannot survive.
Q2: What makes double row tapered roller bearings superior to single row for heavy industrial use?
Double row tapered roller bearings provide significantly higher combined radial and axial load capacity than single row designs, because two rows of tapered rollers share the load — dramatically increasing the bearing's dynamic and static load ratings. The double row configuration also provides greater shaft rigidity, better resistance to moment loads, and improved tolerance to misalignment — all critical advantages in heavy mining, rolling mill, and large gearbox applications.
Q3: What do the dynamic load rating (41,000N) and static load rating (51,000N) mean for the 3510/600?
The dynamic load rating (Cr) of 41,000N represents the constant radial load the bearing can carry for a calculated rating life of one million revolutions. The static load rating (Cor) of 51,000N represents the maximum static load the bearing can sustain without permanent deformation of rolling elements or raceways. For the 3510/600, these ratings confirm its suitability for the highest-load industrial shaft applications — where both sustained dynamic loads and peak static shock loads must be safely managed.
Q4: What clearance and precision grades are available for the 3510/600?
NEXANS Bearing supplies the 3510/600 in the following grades: Clearance: C0 (standard), C2 (reduced), C3, C4, C5 (progressively increased) Precision: ABEC 1, 3, 5, 7, 9 / DIN620 P0, P6, P5, P4, P2Grade selection depends on operating speed, temperature range, load magnitude, and shaft/housing fit requirements. Our technical team provides application-specific grade recommendations — contact us for guidance.
Q5: How is the 3510/600 bearing installed in heavy industrial machinery?
Due to its 500kg weight and 600mm bore, the 3510/600 requires specialized heavy lifting equipment and precision alignment tools for installation. Correct interference fit on the shaft and in the housing is critical, as is proper preload setting to ensure optimal load distribution across both roller rows. Thermal mounting (heating the bearing for installation) is typically required for interference fits at this size.

Q6: What is the cross-reference between 3510/600 and 971/600?
3510/600 and 971/600 are cross-reference designations for the same bearing — used by different manufacturers and catalog systems to identify the identical 600×870×270mm double row tapered roller bearing. NEXANS Bearing supplies this bearing under both reference numbers and can provide documentation in either format to match your procurement and maintenance system requirements.
Q7: Is the 3510/600 interchangeable with SKF, FAG, Timken, or NSK equivalents?
Yes. The 3510/600 is dimensionally equivalent to double row tapered roller bearings from SKF, FAG, Timken, NSK, NTN, and other major manufacturers sharing the same 600×870×270mm dimensions. NEXANS Bearing manufactures this bearing to the same ABEC/DIN620 dimensional and performance standards, ensuring a direct drop-in replacement for maintenance, MRO, and OEM procurement — at significant factory-direct cost savings.
Q8: What are the shipping and logistics considerations for a 500kg bearing?
The 3510/600 bearing weighs 500kg, requiring specialized heavy freight handling. NEXANS Bearing has extensive experience shipping large-format industrial bearings globally, using secure wooden crate packaging, professional heavy freight carriers, and full export documentation including packing lists, commercial invoices, and certificates of origin.
