Product Description

440C bearing steel balls are our main product.

Our best precision of them is G16( the ball diameter variation is 0.4um max. )

Diameter from 2.0mm to 1'' are all ok to us.


Our hot sizes: 2.0mm 2.381mm 2.5mm 3.175mm(1/8'') 4.763mm(3/16'') 5.0mm 5.5mm 6.0mm 6.35mm(1/4'') 7.144mm(9/32'') 7.938mm (5/16'') 8.731mm 9.0mm 9.525mm(3/8'') 11.1125mm(7/16'') 12.7mm(1/2'') 9/16'' 5/8'' 3/4'' 1'' ...

Usually we also have some stock of them.

Advantages

For high precision 440c stainless steel ball bearings, the roundness and surface roughness is very important.

For roundness, we use roundness measuring equipment.

For surface roughness, we use 100 times microscope and 500 times microscope.

We will check each Lot no. steel balls before packing.

Q:The difference between sheet metal and casting parts
Casting parts are made by casting (followed by a variety of processing), the shape can be simple, can also be very complex, usually large parts, as a base, bed, work table, and so on, good seismic performance.
Q:Domestic large steel castings factory which is better, recommend!
At least spend money on research and development, then the quality should be all right.
Q:How can the casting be plated with ordinary zinc plating? The coating is too thin and requires 0.08 thickness
Hot galvanizing doesn't seem to workThe zinc layer is 275g/ square meters of material coating is 0.019mm (mm), up to 0.08 thick.
Q:What are the factors affecting the machining process of the casting material and structure?
The impact on the machining is obvious, it should be the material and heat treatment of the castingCarbon steel parts should be treated by heat treatment (annealing) without special conditions. It can effectively prevent the uneven hardness and hard points. It is easy to turn.
Q:What is the reason for 304 stainless steel precision casting parts to be changed?
304 stainless steel is easier to change than ordinary steel. Because the 304 heat conductivity is lower than that of the low doped steel, the temperature is even more uneven, and 20% of the non ferrous elements also make the distribution of internal and external elements more uneven, hard and soft inside. Each of these two produces greater internal stresses, resulting in a variant.
Q:Casting parts by shot blasting, spray painting, baking after the formation of very small rust spots, how to solve ah?
The first process is very important. Shot blasting must be thorough. The solution is to wipe the surface of the paint with a release. Re shot
Q:What reason is the bronze statue choking fire?
The casting process in boiling phenomenon, is the setting of the exhaust hole positioner position or number is not reasonable, the air cavity can not be discharged, overwhelmed by a material inlet, reflux, change mould, sincerely help you look forward to adopt,
Q:What do you mean by "proofing" in the casting? Do you charge for the proofing?
Proofing refers to making the first sample to confirm to the customer
Q:Cast iron, casting parts 5
1, qualified enterprises will directly iron ore into molten iron, and then poured into the mold, such a good product performance. I work in the cast iron industry, which I can tell you for sure.2, this, like the Great Wall Motor Company has its own parts production department, as well as the corresponding mold center, so it will be their own casting. If the manufacturer does not have these departments, they can only place orders for others to do.
Q:What are the casting parts processing engineering?
Among them, special casting has metal mould casting, pressure casting, low pressure casting, lost wax casting (also known as precision casting), shell casting, lost foam casting, centrifugal casting, continuous casting, V casting, and clay casting
