Traditional Chain CHOHO Solid Bush Chain

S25H Solid Bush

The traditional chain treatment process for the pin sha adopts the traditional C-N treatment, and

the CrV treatment technology and the strengthened pre-tensioning technology of the chain are

used to enhance the surface strength of the pin sha and the fatigue strength of the chain, which

greatly improves the durability of the chain.

Traditional chains mostly use rolled sleeves, S25H

introduces cold forging technology, seamless sleeves

greatly improve the wear resistance of the chain

The Traditional

C-n Treatment

This technology is mainly used in the surface strengthening treatment of the pin sha, which can

make the surface hardness of the pin sha reach 2200HV, and can improve the wear resistance

of the chain by more than 100%

Punching principle

Fine

Blanking principle

The perfect tooth profile design makes the

chain and sprockets in perfect engagement,

stable driving, and low noise.

The minimum pitch divergence ensures the

consistency between chain and sprockets

and chain is not easy to jump.

High-precision dimension, small geometric

tolerance, can guarantee the sprockets

installation accuracy and easier to install.

The shearing surface is 100%

bright, fa

to occur, with beautiful appearance.

Fine Blanking is a kind of technology, with

special-structured precision mould and

customized fine blanking press machine,

to realize small clearance precision

punching, making the materials under

three to compressive stress state with

strong pressure.
