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
Parameter
Value
Significance
Bore Diameter
50 mm
Precision-machined for snug shaft fit, ensuring efficient power transmission and avoiding vibration or premature failure.
Outer Diameter
80 mm
Interfaces seamlessly with housing, distributing radial loads evenly to enhance stability and maintain lubrication clearance.
Width
16 mm
Balances structural integrity and load capacity, determining roller quantity/size for versatile applications.
Weight
0.32 kg
Lightweight design eases installation and reduces system weight, beneficial for mobile or high-speed setups.
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.
