Description
As part of their continuing quality improvement program, the RK Chain factory has made a running production upgrade to their best-selling GB530XSO chain. The new upgraded GB530XSO chains feature heat treated hi-carbon alloy steel components with seamless rollers and shouldered bushings, and are fitted with RK's proprietary RX-Ring seal design. RK's new GB530XSO chains offer quality, performance and unbeatable value, for all but the most demanding high performance applications. RK's 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 percent longer wear life compared to standard O-ring chains. RK's new RX-Ring chains offer tremendous value, plus true quality and performance for all but the most demanding high performance applications. Pin length in mm: 24.9mm. Maximum wear life index: 750. Maximum tensile in pounds/feet: 9500 pounds/feet. Master link type: rivet. Weight in pounds per 100 links: 4.48 pounds.
