The MRDY-120 through MRDY-200 range covers a spectrum of hydrostatic spindle sizes for grinding, turning, and cylindrical/internal grinding, all sharing non-contact oil-film support.
MRDY-120…200 — основной диапазон размеров. Каждый объединяет гидростатику и прямой привод, масштабируясь под станок.
Везде: биение ≤0,1 мкм, жёсткость 5–10×, демпфирование, без ползучести, ресурс бесконечный.
Берите размер под посадку, нагрузку и жёсткость — принцип один.
MRDY-120…200 là dải cỡ lõi. Mỗi model gộp thủy tĩnh và trực truyền, thu nhỏ theo máy.
Mọi model: biên ≤0,1 μm, cứng 5–10×, giảm chấn, không bò, tuổi thọ vô hạn.
Chọn cỡ vừa lỗ trục, tải, độ cứng — nguyên lý giống nhau.
MRDY-120…200 est la gamme de taille centrale. Chaque modèle unit hydrostatique et entraînement direct.
Partout: défaut ≤0,1 μm, raideur 5–10×, amortissement, pas de rampement, vie infinie.
Choisissez la taille selon alésage, charge et raideur—le principe est identique.
MRDY-120…200 ist der Kern-Größenbereich. Jedes Modell vereint Hydrostatik und Direktantrieb, passend zur Maschine.
Überall: Rundlauf ≤0,1 μm, Steifigkeit 5–10×, Dämpfung, kein Kriechen, unendliche Lebensdauer.
Wählen Sie die Größe nach Aufnahme, Last und Steifigkeit—das Prinzip bleibt gleich.
The MRDY-120 to MRDY-200 models form the core size range of Marusaku's hydrostatic spindles. Each integrates a liquid-hydrostatic bearing with a torque or direct-drive motor, scaling shaft and housing dimensions to match different machine envelopes and load cases.
Every model in the range delivers the same foundation: radial runout at or below 0.1 μm, 5–10× rolling-bearing stiffness, oil-film damping, no low-speed crawl, and theoretically infinite life. The difference is simply size and duty—grinding, turning, or cylindrical/internal grinding.
Choose the MRDY size that fits your spindle bore, load, and stiffness target; the hydrostatic principle stays identical across the family.
