YDTech™ supplier of ceramics zirconia ZrO2 needle and cylindrical rollers! OEM of zirconium oxide(ZrO2) rollers,balls,bearings, rings,tube,blocks,shafts in china.

we supply many kinds of ceramic parts

according to the customers' differents

requirements. our products include the

ceramic disc valve, ceramic plunger , ceramic

rod, ceramic shaft, ceramic piston, ceramic

water valve sheet, ceramic pipe sleeve, ceramic loom plunger, ceramic seal ring, special

shape ceramic, zro2 zirconia ceramic roller ,al2o3 alumina ceramic roller ,ceramic knife etc.

the products of ceramic balls and ceramic bearings have been successfully applied in aviation

and aerospace spheres,contributing to a lot for national defense. to date ceramic balls of

various specification in a wide rang of sizes,which are made have been assembled in precision,

high speed main shaft,dental drill,instrument bearing,computer hard disk driver and anti-

magnetic,anti-corrosion,high-temperature applications. non-standard bearing orders to

specifications arranged by customers are also welcomed.

we are specializing in designing and supplying

zirconia ceramic ,such as zirconia ceramic

according to your requirement, we encourage

you to discuss your project with us early to

avoid difficult problems later. we will specify benefits of each material

and discuss various processing techniques which is suitable for your product.

you tell us your requirement, we design and supply the best product for you. your any

comments is the most support for us. the improvement will never end. welcome to your

enquiry including requirement!

ceramic materials, which can be used in

making bearings, include mainly silicon nitride

(si3n4), zirconia(zro2), alumina(al2o3)and so

on. si3n4 is in speaking form,which bearing

steel also had,but zro2,al2o3 fail in a crush form,a catastrophic

failure. !note:non-standard ceramic ball orders to specifications

arranged by customers are also welcomed.

the constant quality control during manufacturing is the guarantee for the good quality and

for the satisfaction of our customer. meeting the specifications and drawings of our

customers are the basis of our quality control. we use many ways and equipment to inspect
