6203-2Z/C3WT Bearing Product Overview & Core Advantages
The 6203-2Z/C3WT is a metric single row deep groove ball bearing designed for reliable performance in demanding applications. Its core advantages stem from its shielded construction (2Z) providing effective contaminant protection, and the specified C3 radial internal clearance which ensures optimal performance in applications with thermal expansion or heavy loads. This combination makes it an excellent choice for high reliability and general industrial use where consistent operation is paramount.
6203-2Z/C3WT Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6203 | Basic model number denoting a single row deep groove ball bearing with a 17mm bore, 40mm OD, and 12mm width. |
| 2Z | Signifies shielded on both sides. This provides protection against contamination while allowing for higher speeds compared to contact seals. |
| C3 | Indicates a greater than normal radial internal clearance. This is advantageous for applications involving thermal expansion or where heavy loads are present. |
| WT | This suffix denotes that the bearing is supplied without lubrication, allowing the end-user to apply a grease suitable for their specific operating conditions. |
6203-2Z/C3WT Bearing Structural Features & Performance Benefits
Shielded Design for Contamination Resistance: The non-contact steel shields (2Z) effectively prevent the ingress of solid contaminants, enhancing bearing service life in dirty environments without significantly increasing friction or operating temperature.
Optimized Internal Clearance for Demanding Conditions: The C3 radial clearance is a key performance feature. It accommodates shaft and housing fits and compensates for thermal expansion in applications with high operational temperatures or heavy loads, preventing premature failure due to excessive preload.
Robust Construction for Radial Load Capacity: Manufactured from chrome steel for both rings, balls, and cage, this bearing is built for durability. Its single row deep groove geometry is optimized to handle significant radial dynamic and static loads.
Versatile Lubrication Options: Supplied without grease (WT), this bearing offers flexibility. Engineers can select a specialized lubricant to maximize performance for specific requirements such as extreme temperatures, high speeds, or specific chemical resistance.
6203-2Z/C3WT Bearing Typical Application Areas
- Electric Motors: Ideal for use in small to medium-sized motors requiring reliable, shielded bearings.
- Industrial Gearboxes and Transmissions: Suitable for supporting shafts and handling radial loads in various gearbox designs.
- Material Handling Equipment: Used in conveyor pulleys, rollers, and other components where contamination protection is needed.
- Agricultural Machinery: Fits applications in pumps, fans, and auxiliary drives that operate in harsh, dusty conditions.
- General Industrial Machinery: A versatile component in pumps, compressors, and blowers where standard ABEC 1 / ISO P0 tolerance and robust construction are sufficient.
