Donghua’s Self-Lubricating Roller (SLR) Chain incorporates special oil impregnated sintered bushings. These extend beyond the inner plates to prevent dirt ingress, giving these chains their self-lubricating characteristics.
Nickel plated throughout to prevent corrosion, and with chemically plated and tempered pins, Donghua’s Self Lubricated (SLR) Chain offers improved wear resistance and added protection in the bearing area. This chain is ideal for use in areas where chain lubrication is difficult or undesirable.
