Description
Overview:
The 6306 C3 Deep Groove Ball Bearing is a single‐row, open‐type radial bearing engineered for smooth, low‐friction rotation in demanding machinery. This genuine NTN component is manufactured from high‐grade bearing steel for strength, wear resistance and long service life. The open face design allows straightforward inspection and re‐lubrication where required. With a 30 mm inner diameter (1.18 in), 72 mm outer diameter (2.83 in) and 19 mm width (0.75 in), it suits a wide range of equipment, including electric motors, pumps, compressors, gearboxes, conveyors and agricultural or garden machinery. C3 internal clearance supports reliable running at higher speeds and temperatures, making it a dependable choice for workshop repairs, plant maintenance and OEM replacements.
Key Features:
- Genuine NTN quality for consistent fit and performance
- C3 internal clearance for thermal expansion and high‐speed operation
- Open face (unsealed) for easy inspection, cleaning and re‐lubrication schedules
- Robust bearing steel construction for durability and long service intervals
- Standard 6306 geometry for wide compatibility across industrial and automotive uses
- Low‐friction deep groove raceways for smooth, efficient rotation
- Dimensions: 30 mm ID (1.18 in), 72 mm OD (2.83 in), 19 mm width (0.75 in)
- Simple press‐fit installation in correctly sized housings and shafts
- Suited to both radial loads and moderate axial loads in either direction
- Reliable choice for preventative maintenance and cost‐effective overhauls
Typical Applications:
Commonly used in electric motors, alternators, pumps, conveyor rollers, fans, blowers, agricultural implements, compact construction equipment, and garden machinery spindles. Suitable for gearboxes and transmission assemblies where a 6306 size with C3 clearance is specified. Ideal for environments where periodic inspection and lubrication are part of routine maintenance.
