The 3519/500 (10979/500) is a 500×670×180mm double row tapered roller bearing weighing 159kg. Both designations refer to the identical bearing — 3519/500 is the GB/ISO standard; 10979/500 is the alternative cross-reference used by some manufacturers and distributors.
Key dimensional fact: At 180mm width, the 3519/500 is the narrowest and lightest bearing in the entire 3519 series — despite sharing the same 41,000N / 51,000N load ratings as all larger series members. This makes it the go-to choice where housing length is constrained at the 500mm bore class.
Internal construction: double cup + two cones + optional spacer — separable, field-maintainable without special tools.
Industry | Typical Use | Selection Reason |
Mining — Crushers | Jaw / cone / gyratory crusher mainshafts | Impact load resistance; contamination exclusion |
Mining — Excavators | Swing drives, crawler finals, bucket wheel drives | Shock & vibration; severe misalignment |
Steel & Rolling Mills | Work roll necks, pinion stand shafts | High combined load; roll neck precision (P5) |
Heavy Gearboxes | Large output / intermediate shafts | High rigidity; compact 180mm width |
Cement & Aggregate | Vertical mill reducers, kiln trunnion drives | Continuous heavy radial load; thermal stability |
Tunnelling | TBM main drives, rotary drilling rigs | Bidirectional axial thrust; extreme shock |

✦ The 3519/500 and 3519/530 are not interchangeable — the 63mm width gap between them is the largest step-change between any two adjacent members in the series. Always verify bore, OD, and width against your equipment drawing.

Q: 3519/500 vs 10979/500 — what's the difference?
Same bearing. 3519/500 = GB/ISO designation. 10979/500 = alternative cross-reference.
Q: Why is the 3519/500 (180mm) so much narrower than the 3519/530 (243mm)?
Each bore class has independently optimized roller geometry — roller diameter, length, count, contact angle, and pitch circle are all calculated separately to achieve the target load ratings. The 3519/500's 180mm width is a geometry outcome specific to the 500mm bore class, not a compromise. The two bearings are not interchangeable.
Q: Recommended clearance for crusher applications?
C3 or C4 — accommodates thermal expansion and prevents preload under impact. For standard gearbox service at ambient temperature, C0 (Normal) is standard. Confirm with your OEM equipment manual.
Q: Recommended precision grade for rolling mill roll necks?
P5 (ABEC-5), catalogued as 3519/500/P5. P0 (ABEC-1) for standard mining and gearbox applications.
Q: Lubrication — rolling mill vs mining?
Rolling mills: circulating oil, ISO VG 220–460. Mining/crushers: EP additive grease, NLGI Grade 2 or 3. Confirm with your OEM equipment manual.
Q: What is the internal construction?
One double cup (outer ring, two raceways) + two cones (inner rings with roller/cage assemblies) + optional spacer. Separable — field-maintainable without special tools.
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 export documentation included at 159kg 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.
