| 2Z | Double-sided steel shields | Provides excellent contamination protection while maintaining low friction |
213-2Z Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry enables efficient handling of radial loads while accommodating moderate axial loads in both directions. With a dynamic load rating of 13,601 lbf and static load rating of 13,151 lbf, this bearing delivers reliable performance under demanding conditions.
High-Speed Capability: Featuring a nylon cage that reduces friction and weight, the 213-2Z achieves a limiting speed of 4,800 rpm. The combination of precision manufacturing and optimized internal clearance (CN group) ensures smooth operation at high rotational speeds.
Maintenance-Free Operation: The double-sided steel shields (2Z) effectively retain the factory-applied grease lubrication while excluding contaminants. This construction provides long-term protection and consistent performance across the operating temperature range of -30°C to 120°C.
Precision Engineering: Manufactured to P0 tolerance class with tight dimensional control (bore and OD tolerance: -0.015mm to 0), this bearing ensures precise fitment and reliable operation in precision applications.
213-2Z Bearing Typical Application Areas
- Electric Motors and generators requiring reliable radial bearing support
- Industrial Pumps and compressors where contamination protection is critical
- Material Handling Equipment such as conveyor systems and gearboxes
- Agricultural Machinery operating in demanding environmental conditions
- Automotive Components including alternators and transmission systems
- General Industrial Machinery requiring cost-effective, maintenance-free bearing solutions
