6203-2RSL/C3 Bearing Product Overview & Core Advantages
The 6203-2RSL/C3 is a metric single row deep groove ball bearing engineered for superior performance in demanding applications. Its core advantages stem from its sealed design (2RSL) and optimized internal clearance (C3), making it an ideal solution for applications requiring robust radial load capacity and reliable operation in contaminated environments. This bearing offers a compact design, high reliability, and is pre-lubricated for maintenance-free service life.
6203-2RSL/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6203: Standard designation for a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width.
- 2RSL: Denotes contact seals on both sides. The "RSL" suffix typically indicates low-friction, synthetic rubber seals that provide excellent protection against contaminants while offering superior sealing performance compared to standard shields.
- C3: Specifies a greater than normal radial internal clearance. This is beneficial for applications with significant thermal expansion, such as in electric motors, or where interference fits are used, ensuring optimal performance under these conditions.
6203-2RSL/C3 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The double-sided contact seals (2RSL) effectively exclude moisture, dust, and other contaminants, significantly enhancing bearing service life in harsh conditions. The seals also retain the factory-applied lubricant.
Optimized Internal Clearance: The C3 clearance group provides operational stability in applications prone to thermal expansion or where tight fits are employed, preventing premature failure due to excessive preload.
High Load Capacity & Durability: Manufactured from chrome steel for both rings and balls, this bearing delivers a high dynamic load rating of 2147 lbf and a static load rating of 1079 lbf, ensuring reliable performance under significant radial loads.
Precision & Speed: Built to ABEC 1 | ISO P0 tolerance class, it offers consistent performance for general industrial use, with a limiting speed of 17,000 rpm.
6203-2RSL/C3 Bearing Typical Application Areas
The 6203-2RSL/C3 is widely used across various industries due to its sealed and robust design. Key application areas include:
- Electric Motors (particularly where C3 clearance is specified)
- Industrial Gearboxes
- Agricultural Machinery
- Material Handling Equipment (conveyors, pulleys)
- Automotive Components (pumps, alternators)
- General Machinery requiring reliable, sealed bearing solutions
