DescriptionDatasheetOEM&Customized

We supply car brake discs at wholesale prices,all parts are manufacturers direct,full inspection process and detection.

Why Choose us?

A. Material Standard:

1) Material all according to US-G3000,HT250 along with US-ASTM are our main material standard for our Rotors.Cast iron is the best material for rotors,it have superior wear characteristics at high temperatures compared to other types of steel,It will not warp.
2) Rotor surface tensile strength245N/mm2, hardness BH187-241;
3) Chemical composition as following:C:3.0-3.3% Si:1.8-2.2% Mn:0.6-0.9% S≤0.12% P≤0.15% Cu:0.2-0.4% Cr:0.15-0.25%

B. Casting Standard:

1) Dimensional tolerance of casting according to GB6416-86
2) Casting surface roughness meet GB606.1-85 standard requirement
3) Non-processing casting surface must have no gas-hole, sand hole and other casting flaws

C. Finished Products Standard:

1) Should not have any casting flaws, Scratch or collision damages on the surface.
2) All burrs, edges and corners shall be clean, and shall not leave traces of black and rough machining casting
3) Rotor surface flatness is less than 0.04mm; while the parallelism is less than 0.06mm, runout within 0.1mm,this is our regular runout for every order from our customer.

D. Available Packaging:

1) As soon as Rotor after cleaning,will be coated with quick-drying anti-rust oil, into a plastic bag sealed.
2) Outer packaging according to customer’s needs to use carton or white / color Box, customer’s tag is ok.

E.Strictly Detection

The use of large automatic CNC equipment, automatic processing to achieve high- precision hole diameter and rotor body precision positioning.

Precision Installation holes,every order with strict inspection.before ship them to you.Deviation rejected!
If you need,when you place orders, we can provide you screw bolt,bearing,bolts and assemble them

Caused by uneven thickness of the rotor body, the braking force, hydraulic changes, and so Brake jitter occurs.Rotor thickness difference means the maximum difference of the rotor body (maximum thickness minimum thickness) (PS: 10mm away from the edge of the rotor, mark 8
points , using the micrometer screw to measure the thickness one point by one point, among this 8 points,the maximum thickness minimum thickness” is the thickness difference. )

Brake disc runout is one main reason to cause thickness difference, According to regulations,TIR(Total Indicated Runout)TIR should be within 0.04mm,Only guaranteed tolerance does not exceed the specified range, the car braking process was smooth, safe, no jitter. If you exceed this range car during braking will be on a security risk. This is one of the most important section of the brake rotor ,we take enough attention to make the rotor quality is good enough, we think quality equals safety.
