ABIS Miniature Ball Bearing Materials
The standard material for ABIS rings and balls is a vacuum degassed high carbon chromium steel allowing for high efficiency, low torque, low noise level and long bearing life.
For bearings requiring anti-corrosion or heat-resistant properties, martensitic stainless steel is used.
