The 3506/119A Tapered Roller Bearing is a high-performance bearing engineered to handle combined radial and axial loads, especially in applications where durability, precision, and load-bearing capacity are critical. Featuring a tapered inner and outer ring raceway with rolling elements arranged at an angle, this bearing is specifically designed to support axial thrust in one direction while also withstanding significant radial forces.
Constructed from premium-quality chrome steel (GCr15 or equivalent), the 3506/119A ensures excellent hardness, wear resistance, and fatigue life under harsh working conditions. The internal geometry is optimized for smooth load transfer and minimal rolling resistance, making it highly suitable for rotating assemblies under sustained stress.
This bearing is often used in industrial drive systems, gearboxes, wheel hubs, and railway axle boxes, where robust performance and consistent reliability are essential. The designation /119A typically indicates a specific matching between cone and cup (inner and outer rings), often signifying a tailored fit or application-specific variation, such as modified internal clearance or geometry.
Key Features:
High Load Capacity: Handles both radial and axial forces efficiently.
Tapered Design: Provides excellent alignment and load distribution for reduced friction and extended lifespan.
Durable Material: Made from high-carbon chromium bearing steel for superior mechanical performance.
Application Flexibility: Suitable for a wide range of heavy-duty and precision machinery.
Precision Engineering: Maintains tight tolerances for vibration-free, stable operation.
Common Applications:
Gearboxes and transmission units
Truck and trailer axles
Agricultural and construction machinery
Rail vehicle wheel sets and axle boxes
Heavy-duty industrial equipment
