BREAKAGE ABRADE FIRE BURN ROLLER  CRACKLE FATIGUE PEELING Do you  encounter such  problem ? *Delivered products to clients, frequent accidents, encoutered a huge quality claim *Problems to find sellers complaints, ignored？！*Refused to accept Delivery  is slow, cause customer dissatisfaction with miss out on important business  ？！*Lose the trust of the customers and credibility,who will guarantee our quality？！New Heat Treatment Process To Solve All Your Worries!! We currently apply for the most advanced non-oxidation  protective atmosphere bainite quenching, the difference between bainite non-oxidation quenching and traditional quenching technique ：The deoxidize layer of part surface is controlled within 0.05mm to ensure the hardness and strength of bearing  production to avoid the fatigue peeling of bearing parts during the application The toughness, abrasive  resistance, and stability strengthened greatly The yield degree and percentage of contraction of cross section Decrease the diffusivity of bearing parts’ crack Strengthen the impact toughness and breaking tenacity of material High purity and inclusion-free ① Bainite oxygenation ④ Before quenching ③ Martensite ② Bainite non-oxidation

 

King of performance ratio

WSW will strive for more substantial interest for our clients in alternative way！！

1he storage of bearing distributors will occupy funds, but cannot provide in time once the end user needs the bearing urgently! bearings factories require MOQ, but the distributors don’t need so much as MOQ, will occupy funds if the quantity reaches MOQ When the end users estimate the bearings will breakdown, they will give short delivery time to lower the cost for maintenance. WSW has abundant stock and rich types for your choose, we can also prepare according to your regular need. The accumulation of production experience makes us do more for customers, we’d like to accept small quantity orders We have good bearing parts suppliers and the agreement for good quality parts to share the production schedule and stock information, we will mark the urgent products for the supervisors to arrange non stop productioin, such small changes will win 15 days for customers

     

1.Because of quantity production, so the lower cost and abundant stock provide us much advantage in the market. With advanced heat treatment equipment, products’quality is much stable ,the cost is lower. Because of our factory outlet, which saves many intermediate links and brings maximum interests for customers Most bearing factories worry about overstock and won’t produce with large stock of bearings Many bearing manufacturers search for factories with heat treatment because they don’t have funds and technique for bringing in heat treatment, so the quality of bearing products is not stable and the cost is higher. Too many beaing distributors make the commotion of price.

100% Reliability 100% Inspect rate

WSW research laboratory own s high quality personnel and technology of bearing measuring and testing equipment. We import direct reading spectrometer from Germany, and also bring in three-coordinate measuring machine, surface roughness tester, roundness measuring equipment, etc at home and abroad.
