RK EXCEL RK-XSO-RING 530 MASTER LINK

RKs RX-ring chains feature an X-ring shaped seal. Viewed in cross-section, the X-ring has two lubrication pools and seal points versus the single seal point/pool design of a regular O-Ring chain. RX-ring technology offers less torsional friction, increased high- stress performance, and a 30% longer wear life compared to standard O-Ring chains. RKs new RX-Ring chains offer tremendous value, plus true quality and performance for all but the most demanding high performance applications.
