BK400SQ-2 | 400 mm 2-Jaw Solid Pneumatic Chuck
The TOP-TOOL BK400SQ-2 is a 400 mm 2-jaw solid pneumatic chuck for air-operated workholding applications. Its two-jaw configuration is suitable for setups that require two-point gripping and repeatable pneumatic clamping.
This pneumatic chuck uses a solid body structure without a through-hole. It is selected according to the workpiece shape, required gripping range, available air pressure and machining conditions.
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.
