NJ1010M Single Row Roller Bearing 50x80x16 For Automotive Industry

NJ1010M Single-Row Cylindrical Roller Bearing (50x80x16mm) for Industrial/Automotive

The NJ1010M is a high-performance single-row cylindrical roller bearing, designed for reliable operation and strong load-handling in diverse mechanical systems, widely used across industries.

Structural Features

Ring Design

• Outer Ring: Smooth inner surface acts as a stable raceway, made from high-quality vacuum-degassed high-carbon chromium steel (e.g., GCR15) for excellent fatigue strength, hardness, and wear resistance under heavy loads.

• Inner Ring with Integral Flange: Integral flange on one side guides rollers and maintains alignment. Crafted from high-grade bearing steel with precise machining for a tight shaft fit, enhancing radial load capacity and providing moderate axial load support (up to ~10% of radial load).

Rolling Element and Cage

• Cylindrical Rollers: Key load carriers, made from chrome steel with strict roundness, surface finish, and dimensional standards. Optimized shape transfers radial loads efficiently, reducing friction and wear.

• Cage: Keeps rollers spaced and aligned, usually steel or high-performance polymer. Allows free movement while preventing collisions, boosting efficiency and extending service life.

Key Dimensions

Technical Performance

Load Ratings

• Radial Dynamic Load Rating: Handles substantial 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.

Speed Ratings

• 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 and Sealing

• Lubrication: Grease for general use, oil for high speeds/extreme temperatures. Pre-lubricated options simplify installation.

• Sealing: Rubber seals (dust/moisture protection) or metal shields (larger debris). Sealed versions extend life in harsh environments.

Application Scenarios

• Industrial Machinery: Supports rollers in conveyor systems and rotating shafts in machine tools (lathes, mills), ensuring smooth material handling and machining.

• Automotive Industry: Used in transmission systems (gear shafts, differentials) and wheel hubs of medium vehicles, handling radial loads for stable drivetrain operation.

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

Product Advantages

• High Radial Load Capacity: Robust construction and quality materials handle heavy radial loads, suitable for heavy-duty applications.

• Smooth Operation: Precision-machined components minimize friction, reducing 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 low total ownership cost, with versatile configurations.

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