6203-2RS1/C4HT22 Bearing Product Overview & Core Advantages
The 6203-2RS1/C4HT22 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed bearing excels at handling radial loads and moderate axial loads in both directions. Its key advantages include a C4 radial internal clearance for specific thermal expansion conditions, high-temperature stability (HT22), and robust sealed construction for long-term, maintenance-free operation, making it ideal for applications requiring high reliability and durability.
6203-2RS1/C4HT22 Bearing Model Code Explained, Specifications & Naming Convention
- 6203: Basic model number for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- 2RS1: Designates contact seals on both sides, providing superior protection against contamination and moisture retention.
- C4: Indicates a greater radial internal clearance than normal (C0), suitable for applications with significant thermal gradients or where interference fits are used.
- HT22: Signifies the use of a high-temperature lubricant capable of operating within a range of -30°C to +120°C.
6203-2RS1/C4HT22 Bearing Structural Features & Performance Benefits
The bearing's performance is derived from its specific design features. The deep groove raceway enables efficient handling of both radial and axial loads. The double-contact seals (2RS1) ensure excellent contamination exclusion, protecting the chrome steel components and high-temperature grease, thereby extending service life. The specified C4 radial clearance prevents operational issues in high-temperature environments or with tight fits, ensuring smooth running. Manufactured to ABEC 1 | ISO P0 tolerance class, it provides reliable and consistent performance for a wide range of industrial applications.
6203-2RS1/C4HT22 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Small Gearboxes
- Industrial Fans and Blowers
- Conveyor Systems and Material Handling Equipment
- Agricultural Machinery and Automotive Components (e.g., alternators, idler pulleys)
