Product Description
Key Features of Double Row Tapered Roller Bearing 350000 Series
(Custom configurations available upon request.)
Double Row Design
Contains two rows of tapered rollers, providing higher radial and axial load capacities compared to single row bearings.
Tapered Roller Geometry
The rollers and raceways are tapered to efficiently handle combined radial and axial loads in both directions.
Compact and Robust Construction
Offers a strong, space-saving solution for applications requiring heavy-duty load support.
Increased Rigidity
Double row arrangement enhances bearing stiffness, improving machine precision and reducing shaft deflection.
Separable Components
Inner rings, outer rings, and roller assemblies can be separated, facilitating easier mounting and maintenance.
High Load Carrying Capacity
Designed for heavy radial loads and significant axial loads in both directions.
Material and Durability
Manufactured from high-quality bearing steel for long service life and resistance to wear and fatigue.
Wide Application Range
Commonly used in gearboxes, heavy machinery, construction equipment, and automotive applications.
Standardized Series
The 350000 series conforms to industry standards for dimensions and tolerances, ensuring interchangeability.
Cage Options
Available with steel or brass cages depending on the application requirements.
Lubrication Compatibility
Suitable for grease or oil lubrication systems depending on operating conditions.
