- Compatible with Standard Hydraulic 3‑Jaw Chuck Dimensions
The external dimensions, draw‑tube thread, and mounting interface match standard hydraulic 3‑jaw chucks, enabling quick and seamless replacement.
- Uses Standard Soft Jaws and T‑Nuts
Featuring 60° serrations with a 1.5 mm pitch, the JP series is fully compatible with commonly available soft jaws, reducing the need for custom jaws and lowering both lead time and cost.
- No Custom Jaws Required, While Maintaining Diaphragm Precision
The JP series retains the high precision and low deformation characteristics of diaphragm chucks, while allowing the use of various soft jaws for greater flexibility.
- No Sliding Components, Long‑Lasting Accuracy
With no sliding parts, the chuck requires no lubrication and has no wear‑related backlash issues, maintaining stable accuracy during long‑term operation.
- Gentle Clamping Force Achievable Under Standard Hydraulic Pressure
The diaphragm mechanism delivers gentle, evenly distributed clamping force without lowering hydraulic pressure, ensuring stable performance for delicate workpieces.
- Ideal for Thin Rings, Thin Tubes, and Fragile Components
Compared with hydraulic 3‑jaw chucks, diaphragm chucks significantly reduce clamping deformation, making them highly suitable for thin‑wall or easily deformed parts.
