SKF Leaf Chains are designed for high load, slow speed tension linkage applications. Often, they are specified for reciprocating motion lifting devices such as forklifts or as counterweight chains for elevators or telescoping equipment, e.g. cranes. The chains are typically supplied in a specific length and connected to a clevis at each end.
The clevis may accommodate “male” ends (inside links) or “female” ends (outside links), as required. SKF Leaf Chains are available in series: AL, BL, LL, FL, 12XX, 15XX, 19XX and 25XX. The AL and BL series are based on American chain standards, while the LL series is based on British chain standards. BL series leaf chains are made according to the ASME/ANSI B29.8 American standard. LL series leaf chains are made in accordance with the ISO 606 international standard. A chain with an even number of pitches has one male and one female end. A chain with an odd number of pitches have either two male or two female ends.
