6238/C4 Bearing Product Overview & Core Advantages
The 6238/C4 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This open-type bearing excels in handling primarily radial loads and is manufactured to ABEC 1 | ISO P0 tolerance standards, ensuring reliable and consistent operation. A key feature is its C4 radial internal clearance, which makes it particularly suitable for applications with significant thermal expansion or where interference fits are used. Constructed entirely from chrome steel, it offers excellent durability and a long service life.
6238/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6238 | Basic Bearing Number | Denotes a single row deep groove ball bearing with a 190mm bore, 340mm OD, and 55mm width. |
| /C4 | Radial Internal Clearance | Indicates a greater than normal radial internal clearance. This is critical for applications involving high temperatures or heavy press fits to prevent operational issues. |
6238/C4 Bearing Structural Features & Performance Benefits
- Robust Construction: The single row deep groove raceway and chrome steel construction (rings, balls, and cage) provide high strength and resistance to wear, contributing to a long operational lifespan.
- High Load Capacity: With a dynamic load rating of 57,326 lbf and a static load rating of 62,947 lbf, this bearing is engineered to handle significant radial loads in heavy-duty machinery.
- Optimized for Specific Conditions: The C4 clearance is a defining performance feature. It accommodates shaft expansion and contraction, making it ideal for applications where thermal management is a concern.
- Versatile Lubrication Compatibility: As an open bearing, it allows for the use of various lubricants (oil or grease) tailored to the specific application's speed and temperature requirements, supporting a limiting speed of 2,400 rpm.
6238/C4 Bearing Typical Application Areas
The 6238/C4 is a versatile component found in a wide range of industrial sectors due to its robust design and specific internal clearance. Common applications include:
- Electric Motors & Generators
- Industrial Gearboxes
- Material Handling Equipment (Conveyors, Pulleys)
- Agricultural Machinery
- Vibrating Screens and Heavy-Duty Fans
