Four Key features
1: Lube Groove, 2: Seamless Bush, 3: Centre Sink Rivet, 4: Ring Coin
Tsubaki, the world’s largest and most advanced manufacturer of chain has released a new 4th generation BS/DIN standard roller chain. The latest generation chain, branded Tsubaki GT4 Winner hosts a number of manufacturing and material developments.
Repeated testing and field data indicate the 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. Tsubaki has committed significant amounts of research and development to making improvements in this area, to reduce wear and chain elongation over a longer period of time - even for standard drive roller chain.
Lube Groove
Tsubaki’s new BS/DIN series roller chain utilise a new production technique to manufacture a seamless bush with grooves incorporated on the inner surface. The lube- grooved 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.
Seamless Bush - Perfectly Cylindrical
The new Tsubaki BS/DIN series chain has a seamless bush with a very precise cylindrical profile and surface finish resulting in better surface contact between the pin and bush along with improved lubricant retention.
Centre Sink Rivet - Easy Disassembly
With Tsubaki’s design of rivet head the chain is easily dis-assembled with an additional benefit being that in the event of the chain being overloaded, the markings on the rivet head will identify pin rotation.
Ring Coin - Increased Transmission Capacity
The Ring Coin connecting link allows the chain to be specified up to its full kW rating. The precision and strength achieved on these components is far beyond that of competitor’s offerings. The typical standard slip-fit connecting link is usually much weaker than the other links. Tsubaki’s Ring Coin technology has overcome that.
CO2 Reduction
Tsubaki takes its environmental responsibility very seriously in its state-of-the-art production facilities. The new BS/DIN series chain contributes significantly to reducing CO2 emissions due to the greatly extended replacement frequency.
A standard box length - 5 metres.
