Adjusts chain slack to maintain normal chain transmission
A large amount of chain slack can cause vibration and noise, and can lead to poor meshing with the sprocket, preventing smooth chain transmission.
We offer a lineup of four types of chain tensioners to eliminate chain slack: TH, TCS, ETS, and TA.
Using Chain Tensioners
We have four types available: TCS type, ETS type, TA type, and TH type.
The main body of the chain tensioner contains two coil springs. The elasticity of these coil springs is used to press the idler sprocket or plastic shoe attached to the tip of the chain, adjusting the slack.
Please refer to the formula below for the relationship between the displacement of the idler sprocket or plastic shoe and the pressing force acting at that time, and use it as a guide when installing and
Tsubaki chain tensioners consist of a main body and an idler sprocket (the TA type is an integrated type with a plastic shoe).
The tensioner body (made of aluminum) is designed to perform tensioning using the elasticity of the built-in coil spring.
The idler sprocket section consists of a sprocket with a built-in bearing (an oil-less bush type is also available as an option for the TH type), mounting bolts and washers.
The sprocket teeth are induction hardened, the TCS and ETS types black oxide finish, and the TH type is plated.
