Description
Overview:
The 6310 C3 Deep Groove Ball Bearing is a genuine NTN open-face bearing designed to keep rotating parts running smoothly in construction, garden, and industrial machinery. Made from hardened bearing-grade steel for strength and wear resistance, it supports mainly radial loads with capability for moderate axial loads in both directions. The C3 internal clearance allows for thermal expansion and higher running speeds without binding. Open-face (unsealed) construction means no shields or seals, making it suitable where external lubrication is used and easy inspection is required. Size: 50 mm inner diameter (1.97 in), 110 mm outer diameter (4.33 in), and 27 mm width (1.06 in). This industry-standard 6310 size is commonly found in electric motors, pumps, gearboxes, compressors, conveyors, and drive assemblies across workshops and job sites.
Key Features:
- Genuine NTN part for dependable quality and compatibility
- 50 mm ID (1.97 in), 110 mm OD (4.33 in), 27 mm width (1.06 in) in the standard 6310 footprint
- Deep groove geometry for high radial load capacity with controlled axial support
- C3 internal clearance for improved performance at higher temperatures and speeds
- Open-face (no seals/shields) for direct greasing, fast inspection, and lower running friction
- Precision-ground raceways for smooth rotation and reduced noise
- Durable bearing steel construction for long service life in demanding environments
- Interchangeable with standard 6310 housings and fits, simplifying replacement
- Suitable for electric motors, pumps, gearboxes, agricultural and garden machinery
- Straightforward to fit with standard tools and practices when following correct handling and lubrication
Typical Applications:
Used in drive ends of electric motors, mower and compactor shafts, pump and fan assemblies, conveyors, gearboxes, compressors, and general transmission layouts. Ideal where reliable radial support and low friction are required, and where external lubrication schedules are in place, such as plant maintenance, workshop repair, and OEM builds.
