TSUBAKI sets new standard for RS roller chain


Tsubaki, the world's largest and most advanced manufacturer of roller 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 materials developments.


Pre Lubrication Lube Groove (LG) Bush
Tsubaki Lube Groove (LG) seamless bushes are precision components and perfectly cylindrical. Our special lube grooves hold 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, and improved lubricant retention.

Easy dis-assembly
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.

Increased Transmission Capacity > Ring Coining
The Ring Coined 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.

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.


Supplied in a new high quality box design for the European market, GT4 Winner is available in sizes 06B to 40B as standard, with larger sizes 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.
