💡 Quelle configuration de lubrification permet à une vis à billes de fonctionner plus souplement à des vitesses élevées ?
Réponse rapide : adaptez le pas, la course et le type de support à la charge et à la vitesse de votre axe.
* Le pas détermine la vitesse d'avance et le couple requis
* Des supports d'extrémité adaptés garantissent un alignement précis sous charge
* Une bonne lubrification réduit la chaleur et l'usure à long terme

Conçu pour assurer un mouvement fluide et une précision constante pendant les longues séries de production.
