Ruby bill

Ruby balls are widely recognized for their exceptional hardness, their remarkable endurance against corrosion and high temperatures. They also have superior wear resistance and reliable dimensional consistency. Designed from a monocrystalline aluminium oxide, these balls have their distinct red shade due to some residual impurities in the material. But it is not only their physical characteristics that make them popular.

Characteristics of ruby balls

  • Material: Monocrystalline aluminium oxide
  • Coloring: Red, due to minor impurities

Are ruby balls automatically lubricated? Yes. Ruby balls have a self-lubrication capacity that reduces the need for an external lubricant, which can add to their operating cost.

Why are ruby balls easy to polish? The ruby material has a crystal structure that gives it an exceptional ability to take a glossy finish when it is polished.

Why don't ruby balls fade? The red colour of ruby balls is due to small impurities in the material, and not to a colouring or coating that could simmer or discolor.

Clearly, the potential of ruby logs is immense. Whether in high-end products or in industrial equipment, they offer undeniable added value in terms of reliability, durability and efficiency+.
