brake s-cam shafts heat treatment

Brake s-camshaft for truck as the important parts which connect the brake drum and brake shafts is the key part.

It's hardness is very necessary to reach 55 hrc.


Our company have two ways for this steps :

  1. whole shaft totally do heat treatment and whole hardness reach the standards requirements.

  2. the key parts of the shaft do heat treatment,the S head,teeth and spline etc parts.


The second way can keep the  cost low and price small.


hope clients choose right way according their ideal price.
