Product Description:

Bull brake cylinders are 100% produced by superior HT200 steel materials,we have already all models of brake cylinders in markets,and our research department is efficient to develop the newest models of brake cylinders,the best quality of our brake cylinders already helps us to promote our brake cylinders to markets of European,North and South American,Middle East and so on,we will insist on the principles to provide our clients the best quality of brake cylinders.

As follows,we are glad to make a brief introduction of our brake cylinders,we will introduce you our brake calipers from their materials,key points,product technique,test programs,packages and shipments,hope this will help to understand us better.

1.The most important part of brake cylinder body parts is the surface roughness inside of it,the surface roughness shall be strictly controlled at Ra0.4um,if not,the friction force between the pistions and wheel cylinder casting parts will be bigger,so it will directly affect the working life of brake cylinders,and it will also cause oil leaking.

2.Another key size of brake cylinders is the space between the pistons and wheel cylinders casting parts,the allowable tolerance of pistions is -0.04mm to -0.07mm,and the allowable tolerance of wheel cylinders is +0.052mm,these sizes shall be strictly controlled,otherwise it will affect the work schedule of pistions and the gas tightness inside of the brake cylinders casting parts.

3.The sizes control between the EPDM rubber boots is also very important.According to different codes of brake cylinders,there are different sizes of boot slots,so we produce the boots on the baiscs of various sizes of boot slots,if not,the boots can't guarantee a good gas tightness,which will cause brake fluids leakage.

As to guarantee that each of our brake cylinder can meet the OE standards,we bought the most advanced CNC machines to manufactur the accurate sizes of different brake cylinders casting parts,especially the surface finishing inside of them,also we have the full-automatic machines to make these installing holes with accurat sizes.All of our production lines are controlled by computers,which can help us to make better quality control system,so our brake cylinders will never let you down.

In order to make sure that each of our brake cylinder can meet the quality standards of clients,we have developed different kinds of test programs.There are five test programs of brake cylinders that are the most effective methods to value the quality of a brake cylinder,they are the test of size and appearance,the hardness test,the strength of extension test,metallography detection and the durability test,together all these tests can not only check the outside sppearance and sizes of our brake cylinders,but also guarantee some important features of brake cylinders,such as the extension strength,the metallpgraphy detection is a kind of test to ensure that the internal chemical components of the brake cylinders is up to the international standards.

1. New PE plastic bag packing of brake cylinders to protect the them from wet air.
3. Stronger and harder paper box with beautiful printing.
4. Up-market printing with an excellent market value.
5. Stylish label of brake cylinders on the top of each box.

We worked with our shipping agency more than ten years, each year we export about 300 containers through them, we treat every client equally, that is to make each order shipped safety and timely.
