628/5-2Z Bearing Product Overview & Core Advantages
The 628/5-2Z is a metric single row deep groove ball bearing designed for high-performance applications requiring precision and reliability. This shielded bearing excels in handling radial loads with excellent operational stability. Its compact design (5mm bore × 11mm OD × 4mm width) makes it ideal for space-constrained assemblies while maintaining high rotational accuracy due to its P6 tolerance class. Pre-lubricated with grease and featuring integrated shields, it offers long-term performance with minimal maintenance.
628/5-2Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Performance Benefit |
|---|---|---|
| 628/5 | Standard deep groove ball bearing series with 5mm bore diameter | Proven design for reliable radial load capacity |
| 2Z | Double-sided steel shields | Effective contamination protection while maintaining high-speed capability |
628/5-2Z Bearing Structural Features & Performance Benefits
Optimized Load Distribution: The single row deep groove raceway geometry ensures efficient radial load distribution, supported by a stainless steel cage that maintains ball alignment at limiting speeds up to 60,000 rpm.
Precision Engineering: Manufactured to P6 tolerance class with CN radial clearance, this bearing delivers consistent performance in precision applications. The chrome steel construction provides excellent wear resistance and durability.
Maintenance-Free Operation: Factory-filled grease lubrication combined with double shields (2Z) creates a sealed environment that protects against contamination while operating within a temperature range of -30°C to 120°C.
