For standard situations, Tsubaki can provide you with two outstanding roller chains:
the GT4 Winner and the ANSI G8
Tsubaki's 8th model upgrade, celebrating 100 years of quality. Pursuing the ultimate in quality, Tsubaki has created the world's highest standard of roller chain.
All ANSI Chains Are Not Created Equal
ANSI defines minimum threshold standards: acceptable, but they won't improve your bottom line. Tsubaki ANSI G8 Chains set the bar higher with design innovations that deliver solid results!
Solid Lube Groove Bush - Our Latest Innovation
Unlike curled bush, Tsubaki SOLID Lube Groove Bush does not have a split. This means that oil cannot leak from the bearing area as a result of that type of manufacturing process. Additional to that innovation Tsubaki developed a unique process to add grooves to the inner surface of the solid bush. This lube groove process ensures longer and better lubrication which results in an extended chain life.
The Lube Groove Bush is available in ANSI sizes RS80 through RS140, perfectly sized for the most demanding applications.
Save Operating Costs and Reduce Downtime
Normally, ANSI chains are removed or replaced due to elongation caused by wear in the pin-bush joint. The patented Lube Groove retains lubricant right where it's needed: in the pin-bush joint. In many applications you'll notice a significant difference in maintenance, operating, and replacement costs due to the increased reliability of the ANSI G8 chains.
Increased kW Rating
Transmission capacity has been increased by applying the patented Tsubaki Ring Coining process on the connecting link plate.
For easy assembling the pin and link plate of a connecting link are slip fit. In general, this type of connecting link has a 20% lower fatigue strength than the chain itself. However, Tsubaki developed a special process to eliminate that loss of Fatigue Strength and still satisfy the customers demand for easy assembly: the patented Ring Coining process. By applying the patented Ring Coining process, Tsubaki generates a cold deformation around the pin hole of the connecting link plate. This results in residual stress around the pin hole and thereby adds strength. By using this process transmission capacity is increased to 100% of that of the base chain.
Constant Quality Level
In pursuit of outstanding quality, every Tsubaki chain is made of a special steel alloy developed by the Tsubaki Engineering Department.
Besides that, Tsubaki produces the ANSI G8 under highly controlled conditions in its advanced heat treatment facilities. This, in combination with the Tsubaki fatigue strength confirmation tests, ensures that our customers can always rely on a constant level of Tsubaki quality.
Since 1917 Tsubakimoto Chain Company has maintained a line-up of cutting-edge chain products with exceptional quality and performance that help end-users meet their power transmission and conveying requirements. Tsubaki is proud to introduce the 4th generation, enhanced BS/DIN European premium chain. The product is available in chain sizes from RF06B up to RS48B*. Simplex, duplex and triplex executions are at your disposal.

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 finishing resulting in better surface contact between the pin and bush, and improved lubricant retention.
Ring Coin: Increased Transmission Capacity
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.
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.
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 strongly extended replacement frequency.
Constant Quality Level
In pursuit of outstanding quality, every Tsubaki chain is made of a special steel alloy, the specification of which has been developed by the Tsubaki Engineering Department, for selected steel mills to work with. Besides that, Tsubaki produces the GT4 Winner under highly controlled conditions in its advanced heat treatment facilities. This, in combination with the Tsubaki fatigue strength confirmation tests, ensures that our customers can always rely on a constant level of Tsubaki quality.
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. 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.
