6207-RS1Z/C3 Bearing Product Overview & Core Advantages
The 6207-RS1Z/C3 is a high-performance single row deep groove ball bearing designed for demanding industrial applications. This metric bearing excels in providing reliable radial load support while accommodating moderate axial loads in both directions. Its key advantages include a robust chrome steel construction for durability, a C3 radial internal clearance for stable operation under thermal expansion, and a versatile one side shielded, one side sealed configuration that offers excellent contaminant protection. Engineered to ABEC 1 | ISO P0 tolerance standards, it delivers consistent precision and is ideal for applications requiring a balance of performance, longevity, and cost-effectiveness.
6207-RS1Z/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6207: Basic model number indicating a single row deep groove ball bearing with a 35mm bore, 72mm OD, and 17mm width.
- RS1: Designates the sealing configuration. R indicates a contact seal (nitrile rubber) on one side, providing superior sealing against contaminants and moisture retention. S1 denotes a non-contact shield (steel) on the opposite side, offering basic protection with lower friction.
- Z: This suffix, when combined with RS1, confirms the specific seal/shield combination described above.
- /C3: Specifies a greater than normal radial internal clearance. This is critical for applications with high operating temperatures or where fits cause a reduction in internal clearance, preventing premature failure due to excessive preload.
6207-RS1Z/C3 Bearing Structural Features & Performance Benefits
Optimized Sealing & Protection: The unique RS1Z combination provides a robust defense against contamination. The sealed side effectively retains lubricant and blocks dust and moisture, while the shielded side offers protection with minimal friction, contributing to a limiting speed of 9,200 rpm.
Robust Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a dynamic load rating of 5778 lbf and a static load rating of 3462 lbf, ensuring reliable performance under significant radial loads.
Thermal & Operational Stability: The C3 clearance is a key feature that accommodates thermal expansion in the shaft and housing, maintaining optimal performance and preventing seizure in applications with elevated operating temperatures (up to 120°C).
Precision & Reliability: Built to ABEC 1 (ISO P0) precision class, it guarantees smooth and quiet operation, minimizing vibration and power loss for enhanced machine efficiency.
