O-Ring Chain 428H 520H 525H 530H

O-Ring Chain Features:

• Quality engineered for strength and durability
• Top quality of the line roller chains. This chain offers allowable working loads that can provide extra load carrying capability and delivery.
• All parts are heat treatment (quenching and tempering) and controlled in a reasonable tolerance range.
• Solid rollers and bushings provide excellent strength and durability under all riding conditions.
• The O-Ring lubrication system keeps the chain properly lubricated and prevents premature elongation by sealing lubricant in and contaminants out of the pin/bushing joint.
• O-Ring chain is mainly suitable for adverse environments, such as water, mud, or dust. So it's more demanding for its performance, and the service life is about 3~5 times than standard chains.
