The NJ1008M is a precision single-row cylindrical roller bearing, designed for robust performance and reliability across diverse mechanical applications, making it a top choice in multiple industries.

• Outer Ring: Features a smooth inner surface as a stable raceway, crafted from premium vacuum-degassed high-carbon chromium steel (e.g., GCR15) for exceptional fatigue strength, hardness, and wear resistance under heavy loads.
• Inner Ring with Integral Flange: Boasts an integral flange to guide rollers and ensure alignment. Made of high-grade bearing steel with precise machining for a tight shaft fit, enhancing radial load capacity and offering moderate axial load support.

• Cylindrical Rollers: Primary load carriers, made from chrome steel with strict standards for roundness, surface finish, and dimensions. Optimized to transfer radial loads efficiently, reducing friction and wear.
• Cage: Keeps rollers spaced and aligned, typically made of steel or high-performance polymers. Allows free movement while preventing collisions, boosting efficiency and extending service life.

• Radial Dynamic Load Rating: Handles heavy continuous/intermittent radial forces, suitable for industrial machinery, automotive components, and power-transmission systems.
• Radial Static Load Rating: Withstands static/slowly changing radial loads without deformation, ensuring stability during startup, shutdown, or standby.

• Reference Speed: Optimal operating speed for peak performance and long life under normal conditions.
• Limit Speed: Maximum speed under specific conditions; requires careful monitoring of lubrication, load, and temperature to avoid accelerated wear.

• Lubrication: Grease for general use, oil for high speeds/extreme temperatures. Pre-lubricated options simplify installation.
• Sealing: Options include rubber seals (dust/moisture protection) and metal shields (larger debris). Sealed versions extend life in harsh environments.

• Industrial Machinery: Used in conveyor systems to support heavy-load rollers and machine tools (lathes, mills) for precise shaft support during cutting.
• Automotive Industry: Applied in transmission systems (gear shafts, differentials) and wheel hubs of small-to-medium trucks, handling radial loads for smooth operation.
• Power-Generation Equipment: Supports rotor shafts in electric motors and generator components, enduring radial/axial forces from high-speed rotation.

• High Radial Load Capacity: Robust construction and quality materials enable handling heavy radial forces, reducing breakdown risks in heavy-duty applications.
• Smooth Operation: Precision-machined components minimize friction, lowering energy use, wear, vibration, and noise.
• Long Service Life: High-quality steel, strict manufacturing controls, and effective lubrication/sealing ensure durability under varying loads.
• Cost-Effective: Wide availability, long life, and low maintenance result in a low total cost of ownership, with versatile configurations.
• Easy Maintenance: Separable components simplify installation/replacement; pre-lubricated/sealed options reduce upkeep, with readily available parts.
