Increased abrasion resistance.

The carburized and induction hardened surface makes the balls last longer and are more resistant to abrasion.

This process takes place under special supervision, which ensures perfect parameters of the furnace and cooling liquid.

Extended service life.

This is due to the material used, which is resistant to cracking and hardened only on the surface, thanks to which the ball is resistant to damage resulting from heavy loads.

Surface hardening prevents the ball's surface from abrasion during operation, but does not cause the ball itself to become brittle.

Corrosion resistance.

All balls are subjected to an appropriate galvanizing process, ensuring high resistance to weather conditions.
