SKF N308-ECP Single Row Cylindrical Roller Bearing 40mm x 90mm x 23mm

The SKF N308-ECP is a high-performance single row cylindrical roller bearing designed to handle heavy radial loads and high-speed applications. This N-series bearing features two integral flanges on the inner ring with a plain outer ring, allowing for axial displacement in both directions to accommodate thermal expansion and shaft deflection.

Key Specifications:

• Bore diameter: 40mm (1.575 inches)
• Outer diameter: 90mm (3.543 inches)
• Width: 23mm (0.906 inches)
• Dynamic load rating: 93 kN
• Static load rating: 78 kN
• Reference speed: 8,000 RPM
• Limiting speed: 9,500 RPM

Design Features:

• Polyamide (PA66) cage with glass fiber reinforcement for high speed capability
• Logarithmic roller profile reduces edge stresses and improves load distribution
• Enhanced flange and roller end geometry promotes lubricant film formation
• Normal radial clearance (CN) for standard applications
• Open bearing design without seals for easy inspection and relubrication
• Separable construction allows inner and outer ring components to be mounted independently

Performance Benefits:

• Low friction operation due to optimized contact geometry
• High axial load carrying capacity from improved flange design
• Enhanced operational reliability under arduous conditions
• Long service life with reduced sensitivity to misalignment
• Suitable for rapid accelerations and peak loads
• Temperature range: -30°C to +120°C (-22°F to +248°F)

The separable design of the N308-ECP facilitates easy mounting, dismounting, and maintenance inspections. Components are interchangeable within the same bearing designation, simplifying inventory management. This bearing meets RBEC 1 (ISO P0) precision standards and ABEC 3 running accuracy specifications, making it ideal for industrial machinery, gearboxes, electric motors, pumps, and other demanding power transmission applications.
