Description
Overview:
The 6303 2RSC3 Deep Groove Ball Bearing is a genuine NTN component (MPN NTN63032RSC3) made from hardened bearing steel for dependable service life. With a 17 mm inner diameter, 47 mm outer diameter, and 14 mm width, it is a standard 6303 metric size that fits 17 mm shafts. The twin rubber seals (2RS) form a closed face to keep out dust and moisture, while the C3 internal clearance allows smooth running at higher speeds and temperatures. Designed to carry both radial and moderate axial loads, it is well suited to construction and garden machinery where reliability matters, including electric motors, pumps, gearboxes, mower spindles and rollers. Factory grease-fill and sealed design help maintain consistent performance with minimal maintenance.
Key Features:
- Genuine NTN bearing for consistent quality and tolerance control
- Standard 6303 size: 17 mm ID x 47 mm OD x 14 mm width
- Closed face with twin rubber seals (2RS) for contaminant protection
- C3 internal clearance for smooth running under heat and higher speeds
- Supports radial and axial loads for versatile use across machinery
- Deep-groove raceways reduce friction and running noise
- Factory-lubricated (greased) and ready to install
- Corrosion-protected steel rings and balls for extended service life
- Suits motors, pumps, drive rollers and mower spindles in harsh environments
