SKF Roller Bearing Single Row Cylindrical 40 mm ID, 80 mm OD, 18 mm Width Shielded C3 Clearance Germany NUP 208 ECP/C3

SKF NUP 208 ECP/C3 roller bearing is a precision single row cylindrical roller bearing featuring a 40 mm inside diameter, 80 mm outside diameter, and 18 mm race width. Designed with shielded ends and a non-metallic cage, this bearing provides smooth, low-noise operation with protection against contaminants. The C3 internal clearance allows for thermal expansion during operation, improving durability under varying load and temperature conditions.

This bearing supports high radial loads with a dynamic load rating of 62 kN and a static load rating of 53 kN, suitable for use in automation, electrical, and mechanical systems that demand reliability at high speeds up to 11000 rpm. Its cylindrical bore type and single row design enable axial locating on one side using a flange or shoulder, while allowing shaft displacement on the opposing side, making it ideal for assembly in motor spindles, conveyor drive rollers, gearbox shafts, and precise test rig applications.

The bearing’s German origin guarantees manufacturing excellence and consistent performance. With a manageable mass of 0.4 kg, installation is straightforward and efficient. Key housing design parameters include minimum abutment diameters da min 47 mm, db min 56 mm and maximum diameter Da max 72.8 mm, with minimum fillet radii of 1.1 mm for mating components.

Non-metallic cage reduces noise and friction for efficient operation. Shielded ends minimize ingress of contaminants, enhancing service life. High radial load capacity with dynamic and static load ratings of 62 kN and 53 kN respectively.

Permits high-speed operation up to 11000 rpm for dynamic applications. C3 clearance facilitates thermal expansion under load conditions. Single-row cylindrical design allows axial location on one side. Commonly used in automation equipment, drum conveyors, and electrical machine rotors.

Manufactured in Germany ensuring quality and reliability. Lightweight design at 0.4 kg enables easy handling and installation. Housing design includes key abutment and fillet radius specifications for proper seating.
