Repeated testing and field data indicate that wear between the bearing parts is a primary limiting factor in overall chain life, particularly in externally lubricated chain types such as BS/DIN standard roller chain. Significant amounts of research and development allowed making improvements in this area, to reduce wear and chain elongation over a longer period of time-evenfor standard drive roller chain.
The BS/DIN series roller chain GT4Winner utilises a new production technique to manufacture a seamless bush with grooves incorporated on the inner surface.The lube-grooved (LG) bush holds oil at the point of contact where the chain needs it most, providing an internal reservoir for lubricant.The result is a chain that lasts longer with lower maintenance costs over the lifetime of the chain.
The seamless bush with a very precise cylindrical profile and surface finish results in better surface contact between the pin and bush along with improved lubricant retention. The design of the rivet head the chain is easily disassembled, in the event of the chain being overloaded; the markings on the rivet head will identify pin rotation.
The Ring Coined connecting link allows the chain to be specified upto its full kW rating offering high precision and strength. The typical standard slip-fit connecting link is usually much weaker than the other links, Ring Coin technology can overcome that.
Furthermore the chain contributes significantly to reducing CO2 emissions due to the extended replacement frequency. It is available in sizes 06B to 48B as standard, larger sizes are available on request in both simplex and duplex variants; a triplex variant is available to order.
