Drawings and parameter data
The interchangeability dimension of o-ring roller chain conforms to ls0 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 chains haft 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 10times that of the standard roller chain only after initial lubrication. The products are widely used in agricultural machinery, motorcycles and other open drives.
