Features & Benefits
High combined load capacity: Due to the tapered roller geometry, this bearing set supports substantial radial loads plus axial (thrust) loads in one direction—ideal for load-intense shafts.
Separable construction (cone + cup): Makes installation and alignment easier; allows proper preload adjustment and mounting flexibility.
Precision manufacturing: NTN quality, case‐carburized steel, appropriate for heavy-duty industrial usage.
Robust for harsh environments: Recognized for use in mining, steel, heavy machinery, and applications with heavy shock loads or high demands.
Typical Applications
Heavy‐duty gearboxes, drive shafts, and transmissions
Mining and aggregate machinery (e.g., roller mills, kilns, crushers)
Axle shafts, construction vehicle drive units
Industrial machine spindles needing thrust & radial support
General industrial situations where shafts are axially located and subject to combined loads
Ordering & Engineering Notes
Ensure proper matching of the cone (25580) and cup (25520) components—this is a bearing set.
Confirm mounting direction of axial load: the bearing set provides thrust support in one direction (check application).
Check preload and shaft/housing fits: tapered bearings require proper seating and axial adjustment for optimal life.
Use correct lubrication and check operating speeds relative to limiting speeds.
Consider the environment: contamination, shock loads, misalignment will all affect bearing performance and service life.
Model: 25580 (cone) / 25520 (cup)
Brand: NTN
Type: Single-row tapered roller bearing set (cone + cup)
Applications: Designed for combined heavy radial loads and significant thrust (axial) loads in one direction, suitable for shafts requiring axial location and/or rotation under load.
