Overview
The NTN 6302LLBC3/1E is a single-row radial ball bearing featuring non-contact double rubber seals. This deep groove ball bearing delivers reliable performance across a wide range of industrial applications, from electric motors to conveyor systems. The sealed design minimizes grease loss and contaminant ingress, extending bearing life and reducing maintenance intervals.
Key Features
- Double rubber seal design (non-contact) for contamination protection
- C3 internal clearance for thermal expansion and speed operation
- Single-row radial ball bearing geometry for radial and axial load support
- Sealed and pre-greased—ready to install without additional lubrication setup
- Suitable for general industrial machinery, electric motors, and rotating equipment
