6209-Z Bearing Product Overview & Core Advantages
The 6209-Z is a single row deep groove ball bearing engineered for exceptional performance in demanding applications. This precision bearing features integral shielded protection (denoted by the "Z" suffix), offering reliable operation and contaminant exclusion. Designed primarily for radial loads, it also accommodates moderate axial loads in both directions. Manufactured to a P6 tolerance class, it delivers high running accuracy, making it ideal for applications requiring smooth operation and high rotational speeds up to 11,000 rpm. Its compact design, combined with pre-lubrication, ensures long service life and reduced maintenance needs.
6209-Z Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance & Benefit |
|---|---|---|
| 6209 | Basic Bearing Series & Size | Indicates a standard metric deep groove ball bearing with a 45mm bore, 85mm OD, and 19mm width. |
| -Z | Shield on One Side | Provides effective protection against contaminant ingress while allowing higher speed operation compared to contact seals. |
6209-Z Bearing Structural Features & Performance Benefits
- Robust Construction: Manufactured from chrome steel rings and balls with a stainless steel cage, this bearing offers excellent durability and corrosion resistance, contributing to a high dynamic load rating of 7891 lbf.
- High-Speed Capability: The combination of the P6 tolerance class, optimized internal geometry, and a lightweight stainless steel cage enables a limiting speed of 11,000 rpm, making it a true high-speed bearing.
- Pre-Lubricated & Low Maintenance: Factory-filled grease lubrication and the Z-shield provide a sealed-for-life solution, reducing maintenance frequency and ensuring consistent performance within a temperature range of -30°C to 120°C.
- Precision Fit & Operation: The tight bore diameter tolerance and standard CN radial internal clearance ensure precise shaft fits and smooth, low-vibration operation.
