**Introduction to NTN Single Row Cylindrical Roller Bearings (ISO Series)**

NTN’s **Single Row Cylindrical Roller Bearings (ISO Series)** represent a cornerstone of precision engineering, delivering exceptional load capacity, rigidity, and operational efficiency for demanding industrial and automotive applications. Designed to meet rigorous ISO standards, these bearings are optimized for high radial loads, moderate speeds, and environments where precision and durability are critical. With advanced materials, precision grinding, and innovative cage designs, NTN’s cylindrical roller bearings ensure reliable performance in machinery, drivetrains, and other high-stress applications.

### **Technical Features & Design Advantages**
NTN’s ISO-compliant single row cylindrical roller bearings incorporate several key features that enhance performance:

– **High Radial Load Capacity**: The bearings utilize a single row of barrel-shaped rollers with optimized line contact, distributing loads evenly across the raceways. This design minimizes stress concentrations, making them ideal for heavy radial loads in industrial gearboxes, electric motors, and construction equipment.
– **Robust Cage Designs**: NTN offers multiple cage options, including pressed steel, machined brass, or polyamide (depending on the series), ensuring stability at high speeds and reducing friction-induced heat.
– **Precision Ground Raceways**: Ultra-precise machining of inner and outer rings reduces vibration and noise, critical for applications like machine tool spindles or automotive transmissions.
– **Interchangeability & ISO Compliance**: Manufactured to ISO dimensional standards (e.g., ISO 15:2017), these bearings ensure seamless integration with existing systems, simplifying maintenance and replacements.
– **Heat Treatment & Material Quality**: NTN employs specialty steel alloys and advanced heat treatment processes (such as carburizing or through-hardening) to enhance fatigue resistance and extend service life under harsh conditions.

### **Performance Benefits**
– **Low Friction & Energy Efficiency**: Optimized roller profiles and surface finishes reduce rotational resistance, improving energy efficiency in applications like electric vehicle (EV) drivetrains or industrial pumps.
– **High-Speed Capability**: Select series feature precision-balanced components and lightweight cages, enabling stable operation at elevated speeds without compromising load capacity.
– **Durability in Contaminated Environments**: Optional sealing solutions (e.g., rubber or metal shields) protect against debris and moisture, making them suitable for agricultural machinery or mining equipment.

### **Typical Applications**
NTN’s single row cylindrical roller bearings are widely used across industries, including:
– **Industrial Machinery**: Gearboxes, compressors, conveyor systems, and printing presses.
– **Automotive Systems**: Transmission shafts, wheel hubs (in some designs), and differential assemblies.
– **Precision Equipment**: Machine tool spindles, robotics, and medical imaging devices requiring minimal runout.

By combining ISO-standard reliability with NTN’s engineering expertise, these cylindrical roller bearings deliver unmatched performance in high-load, high-precision environments. Whether in heavy industry or advanced automotive systems, NTN’s solutions ensure longevity, reduced downtime, and operational excellence.
