NJ1007M Automotive Roller Bearing 35x62x14 Reliable Operation

NJ1007M Single-Row Cylindrical Roller Bearing (35x62x14mm) for Industrial/Automotive

The NJ1007M is a single-row cylindrical roller bearing, engineered for robust performance, high load-handling capabilities, and reliable operation across diverse mechanical applications, making it a preferred choice in multiple industries.

Structural Features

1. Ring Design
   • Outer Ring: Boasts a smooth inner surface as a stable raceway for cylindrical rollers. Crafted from high-quality vacuum-degassed high-carbon chromium bearing steel (e.g., GCR15), it offers excellent rolling fatigue strength, hardness, and wear resistance to withstand heavy loads during continuous operation.
   • Inner Ring with Integral Flange: Features an integral flange on one side to guide rollers and maintain alignment. Made of high-grade bearing steel with precise machining for a tight shaft fit, the flange enhances radial load handling and contributes moderately to axial load capacity.

2. Rolling Element and Cage
   • Cylindrical Rollers: Key load carriers, made from chrome steel with strict roundness, surface finish, and dimensional accuracy. Optimized shape and size efficiently transfer radial loads, reducing friction and wear, with carefully calculated quantity and arrangement to maximize load capacity and smooth operation.
   • Cage: Keeps rollers evenly spaced and aligned, typically made of steel or high-performance polymers. Its design allows free roller movement while preventing collisions, boosting rotational efficiency and extending service life by reducing wear.

Key Dimensions

Technical Performance

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

2. Speed Ratings
   • Reference Speed: Optimal operating speed under normal conditions, ensuring performance, reliability, and long life when adhered to.
   • Limit Speed: Maximum speed under specific conditions; operating near this requires careful monitoring of lubrication, load, and temperature to avoid accelerated wear.

3. Lubrication and Sealing
   • Lubrication: Grease is standard for general use, with oil preferred for high speeds or extreme temperatures. Pre-lubricated options simplify installation.
   • Sealing: Options include rubber seals (for dust/moisture protection) and metal shields (for larger debris). Sealed versions extend life in harsh environments by maintaining a clean, lubricated interior.

Application Scenarios

1. Industrial Machinery: Used in conveyor systems to support heavy-load rollers and in machine tools (lathes, mills) for precise, high-speed shaft support during cutting operations.

2. Automotive Industry: Applied in transmission systems (gear shafts, differentials) and wheel hubs of small-to-medium trucks, handling radial loads and ensuring smooth operation.

3. Power-Generation Equipment: Supports rotor shafts in electric motors and generator components, withstanding radial/axial forces from high-speed rotation and environmental factors.

Product Advantages

1. High Radial Load Capacity: Robust construction and quality materials enable handling heavy radial forces, reducing breakdown risks in heavy-duty applications.

2. Smooth Operation: Precision-machined components and optimized design minimize friction, lowering energy use, wear, vibration, and noise.

3. Long Service Life: High-quality steel, strict manufacturing controls, and effective lubrication/sealing systems ensure durability under continuous and varying loads.

4. Cost-Effective: Wide availability, long life, and low maintenance needs result in a low total cost of ownership, with versatile configurations for specific needs.

5. Easy Maintenance: Separable components simplify installation and replacement; pre-lubricated/sealed options reduce upkeep effort, with readily available replacement parts.
