Our AAR standard couplers are globally recognized as the leading choice for heavy-duty railway wagons. Designed for superior performance, our couplers are constructed with bodies, knuckles, and locks made from quenched and tempered grade E steel. This high-strength structure ensures reliable safety and exceptional interchangeability. By incorporating AAR standard couplers, transportation safety and reliability are improved, and train formation efficiency is enhanced.Types of AAR Standard Couplers:

1. E Type Coupler:
   The latest addition to our range is the E60EE model, approved as an AAR standard coupler in 2000. It offers significant improvements over the previous E60DE model, optimizing the wall of the knuckle side, knuckle tail end face, lock face, and coupler lock face structure. These enhancements effectively control the longitudinal free clearance of the coupler. Our present service includes E60DE, SBE60EE, and SBE60DE with bottom shelf, SE60EE with top and bottom shelf, and SBE67DE with bottom shelf and long body.

2. F Type and FR Type Couplers:
   The F type interlock coupler boasts a high-strength structure, small coupling clearance, anti-creep mechanism, interlock and automatic centering functions, reliable three-state operation, and excellent curve passing performance. On the other hand, the FR type coupler is a rotatable interlock coupler designed specifically for mass goods transportation and turnover discharge. Our present service offers F70DE, SF70DE with top shelf, F79DE with long body, and more for F type couplers. For FR type couplers, we provide FR207AE and FR209E, among others.

3. EF Type Coupler:
   The EF type coupler, developed based on the E and F type couplers, offers increased lateral oscillating quantity to accommodate train curve passing requirements. It is primarily used for railway wagons with longer traction beams. With its high-strength structure and excellent curve passing performance, the EF type coupler provides optimal performance. Our present service includes E68DE, E69CE, SBE68DE with bottom shelf, SE68DE with top and bottom shelf, and more for EF type couplers.
