ZA27, ZA303 as raw material low friction coefficient,long using life,easily processed,light weight ,low cost, non-magnetic.
Roller liner
We supply new type of roller liner use Zinc alloy ZA303, ZA27 as raw meratial. Our liner take place of old brass liners. It can self-lubricate, using life severely longer than trational liners.
1. Low friction coefficient and high thermal conductivity.The using life of our products are 2-3 times longer than copper roller liner.
2.Easily processed.
3.Light weight.The material of our products is 40% lighter than the copper.
4.Low cost. half price compare traditional copper roller lining.
5.Good castability.Our products can be cast into the casting wall thickness of 2.5mm.
6. Used as load bearing in rotary kilnm ball mill, etc.
