How to Select Ceramic Balls Ceramic balls are spherical, rolling elements that provide higher stiffness, lower thermal expansion, lighter weight, increased corrosion resistance, and higher electrical resistance than steel balls. They are made from a variety of ceramic materials. How Ceramic Balls are Made Ceramic balls are manufactured by pressing a ceramic powder binder mixture in a preform shape. After the ball is sintered, the part lines are removed via finish-grinding. Lapping and...

Q:
From your perspective, which companies are creating the most innovative ceramic balls?
6 answers
Answers:
I struggled to find companies in the UK to supply fully ceramic bearing sets, with none supplying Zr bearings. I used a company in the states, VBX bearings.

Q:
Is there any advice you want to share with users to help them avoid common errors in selection or usage of ceramic balls?
3 answers
Answers:
Understand the dynamics of the design. Ceramic balls will deform steel under high compression loading, so make sure the application and the materials are matched.
~Lynda W, Quality Assurance & Process Improvement, E. Granby, CT
Try to record as much data as possible for results for different materials and conditions so you have experience to make the right choice for further needs.
~Ricardo Ramos, Research & Development, Tucson, Pima
Check mechanical resistance.
~Edgar F, General Management, Brussels, Belgium

Buying AdviceTop

Q:
Do you have any advice for people relative to buying or using ceramic balls?
4 answers
Answers:
Know what you want, ask questions and look at the industrial specifications that apply to ceramic balls. Most purchase these balls to a general steel ball specification, that's fine for geometries, but not for physical characteristics. Know what you need and communicate your requirements.
~Lynda W, Quality Assurance & Process Improvement, E. Granby, CT
Buy the right one for your application. Follow up weight reduction versus time for durability for price quality advantages.
~Ricardo Ramos, Research & Development, Tucson, Pima
Focus on compressive strength and fracture toughness.
~George H, Research & Development, Shreve, OH
Pay attention to the sphericity
~Edgar F, General Management, Brussels, Belgium
