High Speed Cylindrical Roller Bearings NJ1011M High Load Bearings
Product Overview
The NJ1011M cylindrical roller bearing is a key component in industrial transmission systems, widely used in various mechanical equipment due to its unique design and excellent performance. This single-row cylindrical roller bearing features an inner diameter of 55mm, outer diameter of 90mm, and width of 18mm, achieving an optimal balance between compact structure and efficient load-carrying capacity for space-constrained applications.
Structural Design
Rolling Elements: High-precision cylindrical rollers made from quality bearing steel provide line contact with raceways, significantly increasing load capacity compared to point-contact bearings
Raceways: Precision-ground inner and outer ring raceways with high surface hardness and smoothness ensure optimal roller movement and stress distribution
Cage: Metal machined solid cage accurately separates and guides cylindrical rollers, preventing collision and maintaining proper roller arrangement during high-speed operation
Rib Structure: Double ribs on outer ring and single rib on inner ring provide one-way axial load capacity and axial positioning capability
Performance Characteristics
High Radial Load Capacity: Line contact design enables excellent radial load performance for heavy mechanical equipment applications
Axial Force Resistance: Rib structure allows bearing of one-directional axial loads while providing reliable axial positioning
High-Speed Operation: Precision manufacturing and optimized design ensure stable performance at elevated rotational speeds
Long Service Life: Quality materials and manufacturing processes contribute to extended operational life and reduced maintenance requirements
Application Fields
Industrial Machinery: Transmission components in automated production lines and reducer input/output shafts
Machine Tool Equipment: Spindle support applications ensuring machining accuracy and reducing vibration
Motor Manufacturing: Rotor shaft support in various motor types for stable, efficient operation
Ventilation & Refrigeration: Equipment such as ventilators and air-conditioning compressors requiring continuous operation
