Deep groove ball bearing NTN 6216C3, Outer diameter: 140 mm | Width: 26 mm | Inner diameter: 80 mm

Thanks to its open design and its internal radial clearance C3, this ball bearing from the NTN brand ensures smooth rotation with low friction. Ideal for applications requiring high speeds, it adapts to environments where heat dissipation is essential. Its sheet steel construction provides good resistance to loads while facilitating maintenance.

Features :
This ball bearing is designed with deep raceways on its inner and outer rings, allowing it to support both radial and axial loads in both directions. Its C3 clearance increases its tolerance to thermal expansion and reduces internal friction, thus promoting improved high-speed performance. Its lack of seals allows easy access for lubrication and simplifies maintenance. The pressed steel cage offers good resistance to shock and steady loads, ensuring an extended service life under controlled conditions. Its quiet operation and low rolling resistance make it a suitable choice for demanding industrial applications.

Maintenance :
Regular lubrication is essential to ensure the longevity and performance of the product. Using a lubricant suitable for the operating conditions helps limit wear and optimize running smoothness. Periodic checks of lubrication level, noise and vibration help anticipate anomalies and prevent premature failures. In case of contamination, thorough cleaning should be performed to remove particles that may impair performance. It is recommended to avoid environments exposed to excessive moisture to reduce the risk of corrosion.

Sealing :
This bearing has no protection against external contaminants, such as dust, particles or liquids. The absence of seals allows optimal heat dissipation and direct access to components for maintenance. However, this also implies increased exposure to impurities and a need for more frequent maintenance or use in a clean, controlled environment.
