**NTN Metric ISO Series Tapered Roller Bearings: Precision, Durability, and Performance for Demanding Applications**

NTN’s Metric ISO Series Tapered Roller Bearings represent the pinnacle of engineering excellence, delivering unmatched reliability, load capacity, and precision in a wide range of industrial and automotive applications. Designed to meet stringent ISO dimensional standards, these bearings are optimized for high radial and axial load performance, ensuring smooth operation under even the most demanding conditions.

### **Technical Features & Design Advantages**
NTN’s tapered roller bearings feature a precision-engineered conical geometry, with rollers guided by a robust ribbed inner ring (cone) and outer ring (cup). This design ensures optimal load distribution, reducing stress concentrations and extending service life. Key features include:

– **High Load Capacity**: The tapered roller design efficiently handles combined radial and thrust loads, making these bearings ideal for applications with complex loading conditions.
– **Precision Ground Surfaces**: Advanced manufacturing techniques ensure ultra-smooth roller and raceway surfaces, minimizing friction and heat generation.
– **Optimized Cage Designs**: NTN offers reinforced steel or polymer cages to reduce weight, prevent roller skewing, and enhance high-speed performance.
– **Heat Treatment & Material Excellence**: Bearings undergo specialized heat treatment processes (such as carburizing or induction hardening) to achieve superior wear resistance and fatigue life.
– **Sealing & Lubrication Options**: Customizable sealing solutions (contact or non-contact) and pre-greased configurations ensure contamination protection and maintenance-free operation.

### **Performance Benefits**
NTN’s Metric ISO Series Tapered Roller Bearings excel in applications where durability and precision are critical:

– **Extended Service Life**: Reduced internal sliding friction and optimized roller alignment contribute to longer operational lifespans, even under heavy loads.
– **Enhanced Rigidity & Stability**: The tapered geometry provides superior axial positioning, improving system rigidity in gearboxes, axles, and transmission systems.
– **Energy Efficiency**: Low friction designs reduce power losses, contributing to improved fuel efficiency in automotive applications.

### **Typical Applications**
These bearings are widely used across industries requiring robust, high-precision rotational solutions:

– **Industrial Machinery**: Gearboxes, conveyor systems, mining equipment, and heavy-duty pumps.
– **Automotive Systems**: Wheel hubs, differentials, transmissions, and axle assemblies in passenger vehicles, trucks, and off-highway equipment.
– **Precision Equipment**: Machine tool spindles, agricultural machinery, and construction equipment where alignment accuracy is critical.
