**TIMKEN Tapered Roller Bearings – Single Cones (Metric Series 473): Precision, Durability, and Performance for Demanding Applications**
TIMKEN’s Metric Series 473 Single Cone Tapered Roller Bearings represent the pinnacle of engineering excellence, delivering unmatched reliability and performance in high-load, high-speed applications. Designed to handle combined radial and thrust loads, these bearings are a critical component in industrial machinery, automotive systems, and precision equipment where durability and efficiency are non-negotiable.
### **Technical Features & Design Advantages**
The Metric Series 473 Single Cones are precision-engineered with an optimized tapered roller and rib design, ensuring even load distribution and reduced stress concentrations. Key features include:
– **High-Quality Steel Construction:** Manufactured from premium-grade alloy steel, these bearings undergo rigorous heat treatment processes to enhance hardness, fatigue resistance, and operational lifespan.
– **Precision Ground Surfaces:** The rollers and raceways are meticulously ground and super-finished to minimize friction, reduce heat generation, and maintain consistent performance under heavy loads.
– **Robust Cage Design:** The reinforced steel or polymer cage securely retains rollers, preventing misalignment and ensuring smooth rotation even in high-vibration environments.
– **Interchangeability & Standard Compliance:** Conforming to ISO metric standards (473 series), these single cones are designed for seamless integration with matching cups, simplifying maintenance and replacement.
### **Performance Benefits**
TIMKEN’s tapered roller bearings excel in applications where both radial and axial loads are present, offering distinct advantages:
– **Superior Load Capacity:** The tapered geometry allows for efficient distribution of radial and thrust loads, making them ideal for gearboxes, wheel hubs, and heavy machinery.
– **Extended Service Life:** Advanced lubrication retention features and wear-resistant materials reduce maintenance frequency and downtime.
– **High-Speed Capability:** Optimized internal geometry minimizes skidding and ensures stable operation at elevated speeds, critical for automotive drivetrains and industrial spindles.
– **Reduced Friction & Energy Loss:** Precision engineering lowers torque requirements, improving energy efficiency in power transmission systems.
### **Typical Applications**
TIMKEN Metric Series 473 Single Cones are widely used across industries, including:
– **Industrial Machinery:** Conveyors, crushers, and mining equipment requiring robust bearings for shock and misalignment resistance.
– **Automotive Systems:** Wheel hubs, differentials, and transmissions where high-load capacity and durability are essential.
– **Precision Equipment:** Machine tool spindles and agricultural machinery demanding tight tolerances and smooth operation.
Engineered for reliability in the harshest conditions, TIMKEN’s tapered roller bearings ensure optimal performance, reduced downtime, and long-term cost savings. Whether in heavy industrial applications or precision automotive systems, the Metric Series 473 Single Cones deliver the strength and precision that keep operations running smoothly.
