Overview: The document provides technical specifications for the Female Double Swivel Ring (FE.DSR) with both metric and UNC threads. It includes details on dimensions, working load limits (WLL), safety factors, and torque requirements.
Specifications:- Metric Threads: The FE.DSR is available in various sizes from M8 to M22. The working load limit (WLL) varies depending on the safety factor (SF), with SF 5:1 ranging from 0.40t to 3.50t and SF 4:1 from 0.50t to 4.50t. Torque requirements range from 6 Nm to 120 Nm.
- UNC Threads: Sizes range from 1/4''-20 to 7/8''-9. The WLL for SF 5:1 ranges from 330 lbs to 7,900 lbs, and for SF 4:1 from 450 lbs to 9,800 lbs. Torque requirements range from 3 ft-lb to 90 ft-lb.
Dimensions: Both metric and UNC versions share similar dimensions, with variations in length (L Maxi) and weight. The metric version has a consistent weight of 0.9 kg for smaller sizes and 2.6 kg for larger sizes, while the UNC version follows a similar pattern.
Key Features:- Both versions are designed to swivel, providing flexibility in lifting applications.
- Standardized dimensions ensure compatibility with various industrial applications.
- High safety factors (5:1 and 4:1) ensure reliability and safety in use.
Recommendations: Ensure proper torque application during installation to maintain safety and performance. Select the appropriate size and thread type based on the specific load requirements and application environment.
