What is an SG3-coated bearing, and what are its advantages?

What is an SG3-coated bearing?

A CEMA SG3-coated bearing is a hybrid ceramic bearing. The bearing consists of ceramic balls and hardened steel raceways to which an ultra-thin protective layer has been applied through a special treatment. 

What exactly is that coating?

The coating on our SG3 bearings is a microscopically thin, hard layer of a corrosion-resistant material that bonds to the surface of the bearing rings through a special process.

What exactly does that coating do?

Cycling rarely takes place under ideal conditions. Rain, mud, and temperature fluctuations have a direct impact on bearings. The coating on our SG3 bearings creates an additional barrier against moisture, oxidation, and dirt particles. Its purpose is to significantly increase the oxidation resistance of the bearing rings and the durability of the bearing. In addition to corrosion resistance, the surface treatment also increases the hardness of the raceways, making them less susceptible to wear and extending their service life. Furthermore, the increased hardness results in reduced friction, ensuring a smoother-running bearing and more efficient power transmission.

The coating ensures:


  • Extra protection against corrosion
  • Longer service life of the bearing rings
  • Increased resistance to wear
  • Longer bearing life
  • Reduced friction

Who are SG3 bearings suitable for?

SG3-coated bearings are designed for cyclists and professionals who refuse to compromise on performance and durability.

They are ideal for:


  • Competitive cyclists
  • Gravel cyclists who ride in varying conditions
  • Mountain bikers who have to deal with mud and dirt
  • Heavy users and competitive riders
  • Anyone looking for a low-maintenance and sustainable solution

Salt Spray Report

The results of a comparative salt spray test conducted on bearing rings made of different materials demonstrate the increased corrosion resistance of the coated bearing rings. ​
