28A-3 Donghua HSP (Heavy Super Power) drive chain

Donghua HSP drive chain shares the thickness of the link plates with the Heavy Duty and Heavy Reinforced drive chains. The special pin material is also through-hardened which provides a higher tensile strength and a higher shock load resistance than Donghua SP drive chains. The pitch holes are critically formed and ball drifted. HSP drive chains can be used to replace the next larger size of ANSI standard roller chain, making them ideal for applications where space is limited. Best suited for low speed operating conditions of up to 50 m/min. All connecting links have standard connecting plates with press fit, these are more difficult to mount but increase fatigue resistance by 15%. Manufactured to ISO 606 DIN8188, this ANSI Drive chain is pre-loaded, has seamless rollers and comes marked with a production batch code number for complete traceability. This Drive chain is pre-lubricated by default, special lubricants for high or low temperatures, food applications or specific environments are available. All Donghua chains are sealed in plastic bags and packed in cardboard boxes with clear descriptions and safety instructions according to ISO 606 DIN8188 Standard packaging size is 5 meters per box, reels are available on request.
