6203-2Z/C2 Bearing Product Overview & Core Advantages
The 6203-2Z/C2 is a single row deep groove ball bearing designed for reliable performance in demanding applications. This shielded bearing excels at handling primarily radial loads and offers a compact, robust solution. Its key advantages include a C2 radial internal clearance for specific operational requirements, a high limiting speed of 17,000 rpm, and pre-lubrication for initial operation. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent quality and is an ideal choice for applications requiring a balance of performance, durability, and cost-effectiveness.
6203-2Z/C2 Bearing Model Code Explained, Specifications & Naming Convention
| Code | Meaning | Technical Significance |
|---|---|---|
| 6203 | Basic Bearing Series & Size | Denotes a metric, single row deep groove ball bearing with a 17 mm bore, 40 mm OD, and 12 mm width. |
| -2Z | Shielded on Both Sides | Provides effective protection against contamination from solid particles while offering low friction and enabling high-speed operation. |
| /C2 | C2 Radial Internal Clearance | Indicates a clearance group smaller than normal (CN), suitable for applications with precise fits, reduced vibration, or where lower operating temperatures are desired. |
6203-2Z/C2 Bearing Structural Features & Performance Benefits
Robust Construction for High Reliability: Manufactured entirely from chrome steel for the rings, balls, and cage, this bearing ensures high strength, wear resistance, and a long service life under radial dynamic loads up to 2147 lbf.
Optimized for Contamination Protection: The non-contact Z-shields on both sides effectively retain the factory-applied lubricant and protect the bearing's interior from dust and debris, enhancing operational reliability.
Precision and Speed Capability: Built to ABEC 1 (ISO P0) tolerance class, it guarantees running accuracy. Combined with the deep groove raceway and C2 clearance, it supports a high limiting speed, making it a capable high-speed bearing for its size.
Versatile Operating Range: With a specified temperature range from -30°C to 120°C, this bearing is suitable for a wide array of industrial environments.
