II. Core Parameters & Performance

【表格】

Specification Technical Details Explanation

Bearing Type Triple-Row Roller (Axial + Radial + Tilt Moment) Independent roller paths for optimized load distribution.

Outer Diameter (D) 1500–5000 mm (customizable) Designed for ultra-large equipment (e.g., offshore cranes, wind turbines).

Bore Diameter (d) 800–2500 mm Matches heavy-duty shafts and gearboxes.

Height (H) 150–350 mm Thicker design for extreme load resistance.

Dynamic Load Rating 5000–50,000 kN (axial/radial) Handles severe cyclic loads (e.g., mining excavators).

Static Load Rating 10,000–100,000 kN (axial/radial) Supports massive stationary loads (e.g., offshore platforms).

Gear Type External/Internal Gear (Module 8–16) External gear for high-torque drive systems; internal for compactness.

Sealing System Triple-lip metal seals + labyrinth Prevents water/salt ingress (IP67/IP68 optional).

Lubrication Method Grease (manual/centralized) + Oil Bath Required for low-speed/high-load applications (up to 150°C).

Material 42CrMo4/34CrNiMo6 alloy steel Ultra-high-strength, case-hardened steel for shock resistance.
