API 8C Single-arm Elevator Link Description Single Arm Elevator Link (also known as elevator bails) is a precision-forged, weldless component designed to optimize performance in oil well drilling operations. Built from high-strength alloy steel with weldless design to enhance structural integrity. And eliminate potential failure points associated with welded connections. As a critical part of Drilling Elevator Bails, this robust construction ensures maximum load-bearing capacity while reducing the risk of fatigue or breakage. Making it ideal for medium-duty applications in onshore and shallow offshore environments. High-Strength Weldless Construction – Eliminates weak points associated with welding, providing enhanced durability and safety. API 8C Compliance – Rigorously tested to meet industry standards for elevator bails used in oilfield drilling operations. High-Strength Alloy Steel – Forged from high quality grade alloy steel with heat treatment, offering exceptional resistance to corrosion, wear, and shear stress. Heavy-Duty Load Capacity – Designed for high-stress environments in oil well drilling, ensuring maximum performance. Elevator Links Specifications Material: Super high-quality structural alloy steel Working Load Limit: 50-750 US tons. Safety Factor: n=2.25~3 Standard: API Spec 8C、GB/T19190 Signs such as WORKING LOAD LIMIT marked on the elevator link. Surface painted with finished paint. Art.
