NBC Deep Groove Ball Bearing 6818ZZ C3
The NBC 6818ZZ C3 is an ultra-thin section, single-row deep groove ball bearing manufactured by National Engineering Industries Ltd. (NBC Bearings). Designed for applications where space and weight savings are crucial without compromising operational precision, it features a 90 mm inner diameter (d), a 115 mm outer diameter (D), and a 13 mm width (B) with a net weight of approximately 0.38 kg.
Dual Metal Shields (ZZ): Equips non-contact steel shields on both sides to retain factory lubrication and shield internal components against dust and particulate contaminants without inducing rotational drag.
C3 Internal Clearance: Offers higher radial internal clearance than standard (CN) ratings, allowing thermal expansion during operation and accommodating heavy press fits without pre-loading or seizing.
Load & Performance Capabilities: Capable of handling combined radial and light-to-moderate axial loads in both directions, providing smooth, low-vibration rotation with dynamic load capacities tuned for high-speed performance.
Industrial Applications: Widely utilized in thin-profile assemblies, robotics, electric gearboxes, automation machinery, textile equipment, and general industrial drive units.
