6220 ZZ NAF 100x180x34 Deep Groove Ball Bearing

Technical details & design features

The 6220 ZZ NAF 100x180x34 mm Deep Groove Ball Bearing is a single-row deep groove ball bearing engineered to dimensions of 100 mm (inner diameter) x 180 mm (outer diameter) x 34 mm (width). The “ZZ” designation indicates metal shields on both sides, offering excellent protection against dust ingress while preserving the low-friction performance characteristic of bearings. The “NAF” suffix denotes the specific manufacturer cataloging and quality level. This bearing accommodates radial and moderate axial loads and supports high speeds. It is designed for industrial-grade applications where stable rotation, minimal maintenance and high service life are essential.

Industrial applications & performance benefits

This ball bearing is ideally suited for demanding industrial applications including heavy-duty gearboxes, large drive shafts, industrial fans, conveyor systems and large-diameter rollers. The combination of standard large size (100x180x34) and dual side shielding makes it a versatile component for machine builders, OEMs and maintenance teams seeking a reliable bearing unit. Its shielding helps reduce contamination risks and extends life in tough environments, contributing to lower downtime and higher productivity. Key search phrases such as “deep groove ball bearing”, “100x180x34 bearing”, “industrial ball bearing” and “dual shield bearing” align with what procurement professionals search for globally.

Benefits for B2B & maintenance teams

• High durability - precision steel raceways plus dual metal shields offer outstanding wear resistance and long operational life.

• Pre-selected size - the 100x180x34 measurement fits typical large-shaft assemblies, simplifying your inventory and replacement strategy.

• Reduced service need - the shielded configuration protects from moderate ingress of debris and supports cleaner running, which translates into fewer outages.

• Versatile integration - suitable replacement in legacy machines or new builds requiring a strong ball bearing element for radial and axial loads.

• Efficient procurement - clear specification and popular size allow quicker purchase decisions and faster lead times for B2B flows.

FAQ

Q: What applications is a 100x180x34 mm bearing suitable for?
A: This size is common in large drive shafts, industrial conveyors, heavy rollers and large-diameter machinery requiring reliable radial support.

Q: What does “ZZ” shielding mean and why is it beneficial?
A: “ZZ” means both sides of the bearing are equipped with metal shields. This offers good protection from external contamination while maintaining low friction and facilitating higher speeds.

Q: Can this bearing handle axial loads as well as radial?
A: Yes. Although primarily designed as radial, the deep groove design supports moderate axial loads in both directions when applied correctly.

Q: What maintenance considerations apply to shielded deep groove bearings?
A: Shielded bearings require less frequent lubrication changes than open types but still benefit from periodic inspection, correct installation and alignment to maximize service life.
