BK250SQ | 250 mm 3-Jaw Solid Pneumatic Chuck
The TOP-TOOL BK250SQ is a 250 mm 3-jaw solid pneumatic chuck for repeatable air-operated clamping of round workpieces.
The three-jaw self-centering structure is suitable for general pneumatic chuck applications where a solid body and repeatable clamping cycle are required.
Key Features
- Air-operated clamping for repeatable loading and unloading cycles.
- Solid chuck body for applications that do not require a through-hole.
- Multiple chuck sizes available for different workpiece ranges.
- Technical parameters are provided for model selection.
Typical Applications
- Pneumatic workholding setups
- Repeat loading and unloading operations
- Machining applications requiring air-operated clamping
- Model selection based on chuck size, gripping range and installation method
Selection Notes
- Confirm the workpiece dimensions and required gripping range.
- Check whether a solid, semi-through-hole or through-hole structure is required.
- Review the allowable air pressure, jaw stroke, clamping force and maximum speed.
- Send the machine information and workpiece drawing for technical review before ordering.
