INA SCE45 Drawn Cup Needle Roller Bearing - 1-1/4 inch Bore - High Dynamic Load Capacity
The INA SCE45 (Series E) Drawn Cup Needle Roller Bearing is engineered for applications requiring maximum load density in a restricted radial space. Featuring a deeply drawn, thin-walled outer ring made from high carbon chromium steel, this bearing is designed for precision press-fit installation directly into the housing bore. The construction allows for significant axial rigidity and high dynamic load capacity, making it an ideal choice where housing bores cannot be extensively machined. The precision-formed outer shell and cage assembly ensure smooth rolling element guidance, reducing friction and maximizing operating lifespan even under fluctuating loads and high rotational speeds.
As part of Schaeffler's premium INA line, the SCE45 offers exceptional reliability and performance consistency crucial for demanding industrial environments. This specific inch-series designation facilitates easy integration into standardized North American designs, commonly found in gearboxes, automotive transmissions, agricultural equipment, and power tools. By eliminating the need for an inner ring (running directly on a hardened shaft), the SCE45 offers a highly cost-effective and simplified assembly solution, driving down overall system complexity while delivering robust, maintenance-free performance.
Key Features
Extremely compact radial cross-section for space-saving installations.
High dynamic and static load carrying capacity characteristic of needle roller bearings.
Cost-effective design when running directly on a hardened and ground shaft (eliminating the inner ring).
Inch series standard designation, simplifying procurement and replacement in existing systems.
Precision-drawn outer cup ensures secure press-fit installation and optimized rigidity.
Suitable for high-speed operation and severe operating conditions.
