SKF NJ 215 ECP Cylindrical Roller Bearing | 75x135x25mm | High-Load Polyamide Cage

The SKF NJ 215 ECP is a high-performance single row cylindrical roller bearing engineered for demanding industrial applications requiring exceptional radial load capacity and high operating speeds. Featuring the optimized E-design internal geometry and robust glass fiber reinforced polyamide (P) cage, this bearing ensures enhanced operational reliability and reduced friction. The NJ configuration allows for axial displacement in one direction, facilitating thermal expansion, and is fully separable, simplifying mounting and dismounting procedures in complex machinery. This component is ideal for use in gearboxes, pumps, electric motors, and heavy machinery subject to continuous, dynamic loads. Selecting the SKF NJ 215 ECP guarantees superior service life and minimizes costly downtime associated with bearing failure. SKF's proprietary heat treatment and manufacturing precision deliver consistent quality and low running noise, translating directly into optimized equipment performance and lower total cost of ownership. The lightweight, low-friction polyamide cage also provides excellent inertial stability, making the NJ 215 ECP a reliable choice for operations requiring higher acceleration and sustained speed capability up to 120°C.

Key Features

  • E-Design Optimization: Enhanced internal geometry maximizes radial load capacity and operational lifespan.
  • Separable Components: Inner and outer rings can be mounted independently, facilitating maintenance and installation.
  • Axial Location: Designed with flanges on the inner ring to accommodate axial displacement in one direction, essential for thermal expansion control.
  • ECP Polyamide Cage: Lightweight, high-strength glass fiber reinforced polyamide cage (P) reduces friction, lowers noise, and allows for higher speeds.
  • High Temperature Resistance: Stable operation under standard operating conditions up to 120°C.
  • Reduced Friction: Precision roller crowning minimizes edge stresses and frictional heat, ensuring cooler running.
