Seal Type
Metal Shielded (ZZ / 2Z)
Metal shields on both sides. Moderate protection from dust and debris. Pre-lubricated with grease.
Best forModerately clean environments. Applications where some contamination is possible but not severe.
Avoid forHarsh environments with heavy moisture, chemicals, or fine dust ingress.
Examples
- Electric motors
- Fans and blowers
- Power tools
- HVAC equipment
Internal Clearance
Greater Than Normal (C3)
Increased radial internal clearance. Required when bearings operate at elevated temperatures or with tight shaft fits.
Best forHigh-temperature applications. Tight interference fits. Electric motors with frequent starts/stops.
Temperature70-150°C operating temperature
