Description
Overview:
The 6307 2RSC3 Deep Groove Ball Bearing is a genuine NTN component designed for reliable service in a wide range of machinery. It measures 35 mm inner diameter, 80 mm outer diameter, and 21 mm width. Built from high‐grade bearing steel with precision‐ground raceways, it provides smooth rotation with low friction while supporting both radial and axial loads. The closed face (2RS) design seals both sides to help keep out dust and moisture and retain lubricant, extending service life. With C3 internal clearance, it is suitable for higher‐speed running and applications where heat expansion occurs. Commonly used in electric motors, pumps, gearboxes, compressors, agricultural and garden equipment, and construction plant, this genuine Japanese NTN bearing is a dependable replacement where accuracy and durability matter.
Key Features:
- Genuine NTN Japanese bearing for consistent performance and long service life
- 35 mm ID x 80 mm OD x 21 mm width for straightforward replacement in standard 6307 housings
- Closed face (2RS) seals on both sides to resist contaminants and help retain lubricant
- Deep groove design supports radial and axial loads with stable running
- C3 internal clearance for higher speeds and thermal expansion without overheating
- Low‐friction raceways for smooth, quiet operation and reduced energy loss
- Manufactured from high‐quality bearing steel with precise geometry for accuracy
- Suited to routine maintenance schedules and easy fitting with standard tools
Typical Applications:
Ideal for electric motors, pumps, fans, conveyor rollers, gearboxes, compressors, small industrial drives, agricultural machinery, garden equipment such as shredders and mowers, and construction tools including compactors and mixers. Use wherever a robust, sealed deep groove ball bearing is needed to carry combined loads and run reliably at speed in dusty or damp conditions.
