**TIMKEN Spherical Roller Bearings: Metric and Inch Accessories with Metric Lockplate – Engineered for Reliability and Performance**
TIMKEN spherical roller bearings are precision-engineered components designed to deliver exceptional load capacity, durability, and misalignment compensation in demanding industrial applications. Available in both metric and inch configurations, these bearings are complemented by high-quality accessories, including metric lockplates, ensuring secure mounting and optimal performance in heavy-duty machinery, automotive systems, and precision equipment.
### **Technical Features and Performance Advantages**
TIMKEN spherical roller bearings are built with a robust two-row barrel-shaped roller design, enabling them to handle high radial and moderate axial loads in both directions. Their self-aligning capability accommodates shaft misalignment up to ±1.5 degrees, reducing stress and wear caused by mounting errors or shaft deflection. The bearings feature advanced heat-treated steel construction for superior fatigue resistance and extended service life, even in harsh operating conditions.
The **metric lockplate** accessory ensures a secure fit by preventing loosening due to vibration or rotational forces, enhancing reliability in high-speed applications. The lockplate’s precision-machined design guarantees consistent clamping force, eliminating the need for additional adjustments during operation.
Key advantages of TIMKEN spherical roller bearings include:
– **High Load Capacity:** Optimized roller geometry and premium-grade materials support heavy radial and axial loads.
– **Extended Service Life:** Advanced lubrication retention and contamination resistance reduce maintenance frequency.
– **Versatility:** Available in both metric and inch sizes, ensuring compatibility with global equipment standards.
– **Reduced Friction:** Engineered surface finishes and optimized internal clearances minimize energy loss and heat generation.
### **Typical Applications**
TIMKEN spherical roller bearings are widely used in industries where reliability under extreme conditions is critical. Common applications include:
– **Industrial Machinery:** Gearboxes, conveyors, crushers, and pulp & paper equipment requiring high load-bearing capacity and misalignment tolerance.
– **Automotive Systems:** Heavy-duty truck axles, off-road vehicles, and drivetrains where vibration resistance and durability are essential.
– **Precision Equipment:** Wind turbines, mining machinery, and steel mill rollers that demand long-term performance with minimal downtime.
By integrating TIMKEN spherical roller bearings with metric lockplates, engineers and maintenance professionals can achieve enhanced operational efficiency, reduced maintenance costs, and improved equipment longevity. Trusted worldwide for their precision engineering and robust construction, these bearings continue to set the standard for performance in mechanical power transmission systems.
For industries that demand reliability under load, misalignment adaptability, and long-lasting performance, TIMKEN’s spherical roller bearings and accessories provide the ideal solution.
