6203/15.875-2Z Bearing Product Overview & Core Advantages
The 6203/15.875-2Z is a high-performance inch series ball bearing designed for precision applications requiring reliable operation. As a single row deep groove ball bearing with integral shields (2Z), it offers excellent radial load capacity while providing effective contamination protection. Manufactured to ABEC 1 | ISO P0 tolerance standards, this bearing delivers consistent performance in demanding industrial environments. Its compact design and standardized dimensions make it an ideal choice for replacement and OEM applications where space constraints and operational reliability are critical.
Model Code Detailed Explanation
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Standard deep groove ball bearing series designation |
| 15.875 | Bore diameter in millimeters (equivalent to 0.625") |
| 2Z | Double-shielded construction providing protection from contaminants on both sides |
6203/15.875-2Z Bearing Structural Features & Performance Benefits
Deep Groove Geometry: The optimized raceway profile enables superior radial load capacity and moderate axial loads in both directions, making it versatile for various mounting configurations.
Double Shield Protection: The 2Z shielded design effectively prevents the ingress of dust and debris while retaining lubricant, extending service life in contaminated environments without the increased friction of contact seals.
Precision Manufacturing: Built to ABEC 1 | ISO P0 tolerance class with CN radial clearance, ensuring smooth operation and reduced vibration levels for general industrial applications.
Material Excellence: Constructed entirely from chrome steel for rings, balls, and cage, providing excellent wear resistance and durability across the operating temperature range of -30°C to 120°C.
