OCM introduces, OSB Series, oil port oriented solid bush roller chain with solid roller. Over 30 years'
experience of manufacturing oil port roller chain made this possible. It incorporates the advantage of solid
bush, cylindrical roundness,making a large bearing area and oil port as oil reservoir.
The large bearing area and oil port,acting as an oil reservoir, improve the wear resistance and prolong the
chain life by 30% as compared with solid bush chain without oil port under no lubricating condition.
Heavy Series differs from standard roller chain in link plate thickness. All the others are identical. There is
no increase in tensile strength, but the thick link plate helps withstand abnormal shock loads.
This chain is more economical than standard roller chain and well suited for applications where shaft
centers are long. Stainless steel chain is available.
