Material Selection, Cages
Ball cages
The ball cage is designed to keep the ball in the ball bearing separated from each other around the partial circle of the bearing.
To be able to find the optimal solution for any ball bearing, myonic has developed many different models of ball cages. These differ both in their construction as well as in the material.
There is no single ball cage that meets all conceivable requirements. The following requirements need to be taken into account in the selection of the optimal ball cage:
■ Starting and running friction moment
■ Rotational speeds
■ Acceleration and deceleration
■ Operating temperature
■ Type and quantity of lubricant
■ Environmental conditions during use (vacuum, chemicals etc.)
■ Noise level requirements
■ External vibrations
■ Self-lubrication
myonic cage “480” Two piece steel ribbon cage tightly crimped
myonic cage “48” Two piece steel ribbon cage loosely crimped for low torque
Two piece steel ribbon cage with coating
myonic cage “23” for highspeed applications
myonic cage “25” highspeed application for angular contact ball bearing type
myonic cage “27” highspeed application for angular contact ball bearing type
Materials for ball cages
aside from metals, myonic can also offer many synthetic materials for ball cages. Some examples:
■ Hard tissue
■ PAI
■ PI
■ PEEK
■ PA
■ PTFE
■ POM
■ Sterilisable hard tissue (myonic patent)
■ Laminated paper
Each material has its advantages depending on the application, lubrication and operating environment.
We highly recommend that you contact the nearest myonic or one of our technicians to make an optimal selection of the cage material.
Customer-specific cage constructions
If none of the listed standard cages is suitable for the requirements of the customer, myonic can also create special constructions that are completely based on customer specifications.
Our research and development team continuously tests new innovative materials and shapes for ball cages to achieve top performance.
