Female spherical rod ends, also known as female rod end bearings, are mechanical articulating joints used in various applications to accommodate misalignment and oscillation. Common sizes and specifications include:
1. **Thread Size**: Female rod ends typically have internal threads. Common thread sizes range from M4 to M30 in metric measurements and from 1/4-28 to 1-1/4-12 in inches.
2. **Bore Diameter**: The bore diameter, which is the hole through the spherical ball, usually matches the shaft size it will accommodate. Common bore sizes range from 4 mm to 30 mm in metric and from 1/8 inch to 1 inch in inches.
3. **Material**: The body is often made from carbon steel, stainless steel, or aluminum, while the spherical ball is typically made from hardened steel or stainless steel for durability and corrosion resistance.
4. **Load Capacity**: Load ratings vary based on size and material, with static load capacities ranging from a few hundred pounds to several thousand pounds.
5. **Misalignment Angle**: The angle of misalignment that the rod end can accommodate typically ranges from 5 to 15 degrees.
6. **Lubrication**: Some rod ends come with lubrication fittings for maintenance, while others are maintenance-free with PTFE liners.
7. **Standards**: Female rod ends are often manufactured to meet standards such as ISO, DIN, or SAE, ensuring compatibility and quality.
8. **Applications**: They are used in automotive, aerospace, industrial machinery, and agricultural equipment, among others.
These specifications ensure that female spherical rod ends can be selected to meet the specific requirements of various mechanical systems, providing flexibility, strength, and reliability.
