New standard for BS/DIN roller chain optimises life

New standard for BS/DIN roller chain optimises life
Tsubaki reports that it has released a new 4th generation BS/DIN standard roller chain. The latest generation chain, branded Tsubaki GT4 Winner, boasts a number of significant manufacturing and material developments.

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. 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.

The new product has four key features, the first being pre-lubrication lube groove. A new production technique is used 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.

Secondly, 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.

The third feature is ease of dis-assembly, thanks to a centre sink rivet. 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.

Finally, you get increased transmission capacity: the Ring Coined connecting link allows the chain to be specified up to its full kW rating. The typical standard slip-fit connecting link is usually much weaker than the other links, but Tsubaki's Ring Coin technology has overcome that.

Tsubaki is also keen to promote its environmental responsibility, and says that the new BS/DIN series chain contributes significantly to reducing CO2 emissions due to the greatly extended replacement frequency.

Supplied in a new high quality box design for the European market, GT4 Winner is available in sizes 06B to 48B as standard, larger sizes are available on request. Both simplex and duplex variants are available; with a triplex variant available to order and as a stock item later in the year. Stock of the new GT4 Winner chain will be held by Tsubaki throughout Europe and by many leading distribution partners, making it available for next-day delivery in most areas.
