Xinzhou Bearing Industrial Inc. is a specialty/Custom Bearing Manufacture,specialized in full ceramic bearings,hybrid bearing,thin section bearings.Bearings(Inch & Metric Sizes )made from Ceramic(Si3N4/ZrO2),stainless(440C/316) or Chrome Steel(SAE52100 steel);Tolerance ABEC1,3,5,7 level.We work directly with our OEMs and bearing distributors.Our engineers can help you with bearing,shaft and housing tolerances as well as semiconductor applications,cryogenic applications,extreme hostile environments,and extreme delta T temperatures environments.Our quality is ranked # by bearing distributors and OEM's.Our physical coating rings,ceramic balls and Moly/PTFE retainers give you the longest lasting best performing bearings in the industry.We are uniquely positioned to provide OEM's and Distributors a full rang of engineered solutions in addition to stocking thousands of bearing and bearing related products to cost-efficiently and consistently provide just-in-time delivery.
Custom silicon carbide ceramic SiC grinding 5mm bearing ball for baking
59% lighter than steel ball, which means less centrifugal force and less wear on thegroove during
high speed and acceleration. 44% larger elastic modulus, which means less deformation under load.
Harder with Rockwell hardness as 78. Smaller friction coefficient. Only 1/4coefficient of thermal
expansion of steel, can endure sharp fluctuation of temperature. Superior surface finishcan be
achieved. Can endure high temperature with high hardness and strength up to 1050C. Never rust,
and can roll without lubrication. More corrosion resistant than steel. Free of metalcontamination.
Non-magnetic. Electric isolation.
High precision bearing balls,high speed ,vacuum,fixed anode X-ray tube, high temp,low temp,electric insulation,
high precision ballscrew set,valve balls for acid,alkali,salt,measure pumps,flowmeter.
Compared with steel,ceramic balls have following advantages
59% lighter than steel ball, which means less centrifugal force and less wear
on the groove during high speed and acceleration.
Larger elastic modulus
44% larger elastic modulus, which means less deformation under load
Harder with Rockwell hardness as 78
Smaller friction coefficient
Low thermal expansion
Only 1/4 coefficient of thermal expansion of steel, can endure sharp
fluctuation of temperature
Superior surface finish can be achieved, Ra could be 4~6 nm
Can endure high temperature with high hardness and strength up to 1050°C
Never rust, and can roll without lubrication.
More corrosion resistant than steel
Free of metal contamination
Non-magnetic while steel is magnetical
Electric isolation while steel is electrified
No metal corrosion
No adhesive-wear with metal
Contact angular is very large with molten and nearly no reaction
Ceramic ball especially Si3N4 have the following performance as low densith ,high strength,low friction coefficient ,electrical and magnetism resistance ,wear rigidity ,lubrication and maintenance free when working ,it's the best choice for rollers(inner and outer ring are made by metal)of the hybrid construction ceramic ball bearing which are used in high-speed,high accuracy and long life environments.Normally,GCr15 or AISI440C,316 304 makes inner ring and outer ring;The ceramic ball can adopt ZrO2,Si3N4 or Sic.
Now we can produce four kinds of ceramic bearing balls: ZrO2 ceramic balls,Si3N4 ceramic balls,SiC ceramic balls and Al2O3 ceramic balls.
We can supply specifications from 0.4mm to 100mm,and grade G5 to G60.
Delivery:In stock for delivery or lead time available.
Packing:Standard package or by customer's request.
