Because the shaft never touches the bearing surface, there is no contact wear. Hydrostatic bearings offer theoretically infinite life—limited only by oil quality and system care, not by material fatigue.
Роликовые изнашиваются от касания. Гидростатика убирает причину: вал не касается поверхности.
Нет контакта — нет усталости и износа. Ресурс бесконечен, ограничен лишь чистотой масла и уходом.
Точность и жёсткость стабильны всю жизнь станка.
Ổ lăn hỏng vì chạm và mỏi. Thủy tĩnh bỏ nguyên nhân: trục không chạm mặt ổ.
Không tiếp xúc — không mỏi, không mòn. Tuổi thọ vô hạn, giới hạn chỉ bởi dầu và bảo dưỡng.
Độ chính xác và cứng ổn định suốt đời máy.
Les roulements échouent par contact et fatigue. L'hydrostatique supprime la cause: l'arbre ne touche pas la surface.
Pas de contact—pas de fatigue ni d'usure. Durée infinie, limitée par l'huile et l'entretien.
Précision et raideur restent stables toute la vie de la machine.
Wälzlager versagen durch Berührung und Ermüdung. Hydrostatik beseitigt die Ursache: Welle berührt die Fläche nicht.
Kein Kontakt—keine Ermüdung, kein Verschleiß. Lebensdauer unendlich, begrenzt nur durch Öl und Pflege.
Genauigkeit und Steifigkeit bleiben über die Maschinenlebensdauer konstant.
Rolling and sliding bearings fail because surfaces touch, fatigue, and wear. Service life is finite and degrades accuracy as clearances grow. Hydrostatic bearings remove the root cause: the shaft or table rides on a pressurized oil film and never contacts the bearing surface.
With no contact, there is no material fatigue and no progressive wear. Hydrostatic support offers theoretically infinite life—its real limits are oil cleanliness (NAS 5+), correct temperature, and routine monitoring, not bearing wear.
Accuracy and stiffness stay constant for the machine's working life. Capital invested in a hydrostatic spindle or table is protected against the gradual degradation that forces rolling-bearing machines into retirement.
