All RK Sealed chains feature heat-treated hi-carbon alloy steel components, giving unrivalled wear life. Seamless rollers allow the chain to run freely between the teeth of the sprocket and reduce chain vibration. All RK seals are made from an advanced Nitrile Butadiene composite for maximum performance and wear life.

As part of their continuing quality improvement program, the RK Chain Factory has made a running production upgrade to their bestselling XSO chain line. The XSO chains feature RK's proprietary "RX-Ring" seal design. Viewed in cross-section, the RK "RX-Ring" has two contact lips and one lubrication pool versus the single seal point/pool design of a regular O-ring chain. RK's XSO chains offer quality, performance and unbeatable value, for all but the most demanding high-performance application.
