NSK spherical roller bearings 22207CAME4 35x72x23mm
The NSK 22207CAME4 is a high-performance double-row spherical roller bearing engineered to excel in harsh industrial environments requiring heavy load capacity, self-alignment, and long service life. Designed with advanced internal geometry and premium materials, this bearing is a trusted choice for a wide range of machinery, delivering consistent performance even under conditions of high radial loads, moderate axial loads, and shaft-housing misalignment.
Key Design Features & Advantages
- Optimized Internal Configuration (Suffix A): Features a modified internal design with optimized roller profiles and raceway curvature, reducing stress concentration and enhancing load distribution. This design significantly improves fatigue life and resistance to impact loads.
- Robust Cage Design (Suffix C & M): Equipped with a machined solid brass cage (C) that is roller-guided (M). The brass cage offers superior rigidity, heat resistance, and wear resistance compared to pressed steel alternatives, making it ideal for high-speed and heavy-load applications. The roller-guided design ensures stable cage operation, even in variable load conditions.
- Efficient Lubrication System (Suffix E4): The outer ring is manufactured with circumferential oil grooves and multiple oil holes, enabling continuous and uniform lubricant distribution to the bearing’s contact surfaces. This feature is critical for extending service life in high-temperature, high-speed, or dusty operating environments.
- Exceptional Self-Alignment Capability: The spherical shape of the outer raceway allows the bearing to compensate for shaft-housing misalignment of up to 2°, eliminating additional stress on the bearing and adjacent components. This makes it suitable for machinery with imprecise mounting or dynamic shaft deflection.
- Premium Material & Heat Treatment: Utilizes NSK’s high-quality bearing steel (SUJ2) and advanced heat treatment processes, ensuring excellent hardness, toughness, and wear resistance. The bearing’s surfaces are precision-ground to strict tolerances, reducing friction and vibration during operation.
