The 3519/560 / 10979/560 is a metric large-bore double row tapered roller bearing with a 560mm bore, 750mm OD, and 213mm width, weighing 235kg per unit. Positioned in the mid-range of the NKS 3519 series — above the 3519/530 and below the 3519/600 — it serves the 560mm shaft diameter class across a broad spectrum of heavy-industry applications, most notably large industrial gearboxes, mining machinery, rolling mills, and hoisting equipment.
The 3519/560 is specifically identified for heavy-duty applications such as gearboxes, mining machinery, rolling mills, and hoisting equipment — where the bearing must simultaneously withstand high radial loads and bidirectional axial loads with maximum structural rigidity. Its double-row tapered roller geometry — comprising a double cup, two cones, and an optional spacer — distributes load across the full roller-to-raceway line contact, maximizing fatigue life and resistance to edge stress under the misalignment conditions inherent in heavy rotating equipment.
A notable dimensional characteristic of the 3519/560 is its 213mm width — sitting between the narrower 3519/600 (205mm) and the wider 3519/530 (243mm). This balanced cross-section reflects an independent internal geometry optimization for the 560mm bore class, delivering the 41,000N / 51,000N load ratings within a moderate axial footprint that suits the widest range of equipment housing designs at this bore size.
The 3519/560 is cross-referenced as 10979/560 — both designations refer to the identical bearing. NKS manufactures this bearing from GCr15 chrome steel (AISI 52100 / 100Cr16 / SUJ2 / 683/XVIII / SKF3 equivalent) — the same alloy specification used by TIMKEN, FAG, NSK, and NTN for this bearing class — with full dimensional and load rating inspection conducted at our facility in Liaocheng, Shandong, China before every shipment.
Industry | Typical Application | Why This Bearing |
Heavy Industrial Gearboxes | Large output shafts, intermediate shafts, multi-stage speed reducers | High rigidity; bidirectional axial load; balanced width for standard housing envelopes |
Mining & Minerals | Crusher mainshafts, ball mill trunnions, conveyor head drives | Contaminated environment; severe misalignment; heavy impact loads |
Steel & Rolling Mills | Work roll necks, pinion stand shafts, intermediate roll drives | High combined radial + axial load; shock & vibration resistance |
Hoisting & Lifting Equipment | Industrial crane slewing rings, winch drums, drawworks | High static load; cyclic combined load; long service life |
Cement & Aggregate Processing | Vertical mill reducers, kiln trunnion drives, rotary drum drives | Continuous heavy radial load; thermal stability; contamination exclusion |
Heavy Construction Machinery | Rotary drilling rig main drives, large excavator swing drives | Bidirectional axial thrust; contaminated environment; shock resistance |
The 3519/560 is specifically identified for heavy-duty applications including gearboxes, mining machinery, rolling mills, and hoisting equipment — withstanding high radial loads and bidirectional axial loads with high structural rigidity.

A key observation: the 3519/560 at 213mm width is narrower than the 3519/530 (243mm) despite having a larger bore — and at 235kg is lighter than the 3519/600 (266kg) despite being an intermediate size. This reflects independent internal geometry optimization for each bore class in the 3519 series, where width and weight do not follow a simple linear progression. Always verify bore, OD, and width against your equipment drawing before ordering.

The 3519/560 occupies the mid-range position in the NKS 3519 series — the transition point between the lower mid-range (3519/530) and the compact large-bore class (3519/600 and above). For 530mm shaft diameters, see the NKS 3519/530 listing; for 600mm shafts, see the NKS 3519/600 listing.

Double row tapered roller bearings deliver high load carrying capacity, axial load support in both directions, and high stiffness — the three defining performance attributes for the 3519/560 across its gearbox, mining, rolling mill, and hoisting equipment applications.
The 560mm bore class is a widely specified size in large industrial gearboxes, mining crusher drives, and rolling mill pinion stands. NKS maintains verified production access and stock capability at this bore size, sourced from China's top-tier large bearing factories. Every 235kg unit undergoes full dimensional inspection and load rating verification before shipment.
The 3519/560's 213mm width provides a balanced cross-section that fits the widest range of standard equipment housing designs at the 560mm bore class — neither as narrow as the 3519/600 (205mm) nor as wide as the 3519/530 (243mm). This makes it the most versatile mid-range specification in the series for retrofit and replacement applications.
At 235kg, the 3519/560 is the lightest bearing in the NKS 3519 mid-range — lighter than both the adjacent 3519/530 (~260kg) and 3519/600 (266kg). This reduces installation handling complexity, crane lift requirements, and shipping costs.
The separable double cup / dual cone / optional spacer construction allows field assembly and disassembly without specialized tools — a critical maintenance advantage for mining and rolling mill equipment operating in remote or high-downtime-cost environments.
Available in GCr15 / AISI 52100 / 100Cr16 / SUJ2 / 683/XVIII / SKF3 chrome steel grades — covering all major international material standards. Carburized steel options available for applications requiring enhanced surface hardness.

Both designations refer to the identical bearing — 560×750×213mm double row tapered roller bearing. 3519/560 is the Chinese GB/ISO standard designation; 10979/560 is an alternative cross-reference designation used by some manufacturers and distributors. NKS lists both for search and procurement convenience.
This is one of the most frequently asked questions about the 3519 series. The width of each bearing in the series is determined independently by the internal geometry optimization for that specific bore class — roller diameter, roller length, roller count, contact angle, and pitch circle diameter are all independently calculated to achieve the target load ratings (41,000N Cr / 51,000N Cor) at each bore size. The 3519/560's 213mm width is the result of a roller geometry that achieves full load ratings within a narrower axial envelope than the 3519/530. This is not a compromise — it is a deliberate engineering outcome. The 3519/560 cannot be substituted with a 3519/530 in a 560mm housing, and vice versa. Always verify bore, OD, and width against your equipment drawing before ordering.
The 3519/560 consists of: one double cup (outer ring with two raceways), two cones (inner rings with tapered roller and cage assemblies), and an optional spacer between the two cone assemblies. This separable construction allows field assembly and disassembly without specialized tools — a significant maintenance advantage for large equipment where in-situ bearing replacement is required.
The 2kg difference between NKS's 235kg and TradeBearings' 237kg is within normal manufacturing tolerance for a bearing of this size and reflects minor variations in measurement methodology (gross vs net weight) or cage material between production batches. Both figures are consistent with the expected weight for a 560×750×213mm double row tapered roller bearing. Confirm the exact net weight with NKS at time of order if your logistics planning requires precise unit weight data.
For mining crusher applications — characterized by heavy impact loads, elevated operating temperatures from friction, and potential for thermal expansion of the shaft — C3 or C4 clearance is typically recommended. The increased internal clearance accommodates thermal expansion during operation and prevents bearing preload under impact loading conditions. For standard gearbox applications at ambient temperature, C0 (Normal) clearance is standard. Always confirm with your OEM equipment manual or crusher manufacturer's specification.
For stock items: 5–7 business days. For made-to-order or special-configuration units: lead time confirmed at order placement. NKS supports FOB Qingdao, CIF, and EXW Incoterms. Given the 235kg unit weight, NKS provides full wooden crating, sea freight logistics coordination, and handling documentation as standard.
