- Compatible with US‑standard 5C collets / Japan‑standard YB‑25 collets
- Built‑in hydraulic rotary cylinder
- Designed for 4‑axis / 5‑axis machining center automation
- Front‑mounted on the rotary table without interfering with table tilting
- Hydraulic actuation provides high clamping force
- Equipped with a radial shaft seal (skeleton oil seal) for superior sealing performance
- Lip‑type sealing structure maintains continuous contact with the shaft surface
- Provides significantly better resistance to coolant and water ingress compared to pneumatic sealing
- Offers bidirectional sealing: prevents internal hydraulic oil leakage while blocking external coolant, chips, and fine debris
- Stable sealing performance under high‑speed rotation and varying pressure conditions
- Enhances service life of the rotary cylinder and bearings by keeping contaminants out
- Reduces maintenance frequency and improves long‑term operational reliability
