SKF 6205 ETN9 C3 Deep Groove Ball Bearing 25x52x15

Overview

The SKF 6205 ETN9 C3 is a premium single row deep groove ball bearing measuring 25x52x15 mm. It features a reinforced glass fiber reinforced polyamide ETN9 cage and C3 internal clearance, making it ideal for applications operating at high speeds, elevated temperatures and continuous industrial duty. The optimized internal geometry provides excellent running accuracy, reduced friction and long service life in demanding OEM and maintenance applications.

Industrial Applications

The SKF 6205 ETN9 C3 is widely used in electric motors, pumps, gearboxes, compressors, industrial fans, conveyors, agricultural machinery, machine tools, automation systems and industrial power transmission equipment. It operates together with rotary shaft seals, oil seals, shaft seals, radial shaft seals, bearing housings, transmission components, industrial sealing systems and rotating shafts.

Construction

The bearing incorporates precision-ground deep raceways and a single row ball design capable of supporting radial loads together with moderate axial loads in both directions. The reinforced internal design (E) provides increased load capacity, while the ETN9 glass fiber reinforced polyamide cage reduces weight, minimizes friction and contributes to quieter operation. The C3 internal clearance compensates for thermal expansion during high-speed operation, improving bearing reliability and service life.

Material

The SKF 6205 ETN9 C3 is manufactured from premium through hardened bearing steel with precision-ground raceways and rolling elements. The ETN9 cage is produced from high-performance glass fiber reinforced polyamide, offering excellent mechanical strength, low mass and outstanding dimensional stability under demanding operating conditions.
