O-Ring chains

● The interchangeability dimension of o-ring roller chain conforms to ISO standard and matches with standard sprocket; O-ring seals are installed between the outer and inner chain plates to prevent grease loss and sundries from entering the gap of the chain shaft sleeve during use, which is suitable for the use environment with high wear resistance and unable to lubricate frequently.

● Under the test condition, the wear resistance of O-ring roller chain is more than 10 times that of the standard roller chain only after initial lubrication. The products are widely used in agricultural machinery, motorcycles and other open drives.
