Perfect component synthesis for low-friction rotational movement
Maximum precision and quality down to the smallest dimensions

The ball guide element is a complex assembly consisting of 24 individual parts and different materials.
The element is composed of a base body, guide and contact balls, and a limiting ring and a cap.
The limiting ring and cap made of aluminium keep the element in shape.
The base body is formed by a precisely ground and polished dome shape made of zirconium oxide.
20 sapphire contact balls are positioned in this dome shape.
Mounted on the small sapphire balls is a guide ball, which is thereby capable of small rotational movements with minimal friction.
