Product Overview
The JTBY-160PV-305 is a precision square-hole laser chuck set designed for tube laser cutting machines that process round tubes, square tubes and structural profiles. This tube laser cutting chuck supports round tubes from Ø8 to Ø165 mm and square tubes up to 165 × 165 mm, making it suitable for medium-size metal tube and profile cutting applications.
Its front-and-rear chuck configuration provides stable workpiece clamping during laser cutting, while the square-hole structure expands compatibility with I-beams, channel steel and selected special-shaped profiles. With a combined load capacity of up to 120 kg, this laser chuck for tube cutting machines is ideal for manufacturers seeking flexible, precise and reliable clamping for mixed-profile production. Custom auxiliary jaws are available for non-standard workpieces.
Why Choose This Model
The JTBY-160PV-305 is designed for tube laser cutting applications that require one chuck system to handle multiple workpiece shapes within a medium-size processing range. Its square-hole design provides broad compatibility with round tubes, square tubes and selected structural profiles, making this model particularly suitable for mixed-profile processing.
Square-Hole Design for Mixed Profiles
The square-hole laser chuck accommodates round tubes from Ø8 to Ø165 mm and square tubes up to 165 × 165 mm. It can also handle compatible I-beams, channel steel and special-shaped profiles within the allowable jaw range.
Front and Rear Chuck Configuration
This tube laser cutting chuck is supplied as a front-and-rear chuck set, providing a matched clamping solution for tube laser cutting machines rather than a single standalone chuck.
120 kg Combined Load Capacity
The maximum combined load capacity of the two chucks is 120 kg, giving machine builders and end users a clear reference when matching the chuck to workpiece weight.
Flexible Jaw Options for Non-Standard Workpieces
For profiles that exceed the effective range of the standard jaws, custom auxiliary jaws can be added. This makes the JTBY-160PV-305 a practical laser chuck for tube cutting machines that process a mix of standard tubes and non-standard profiles.

Workpiece Compatibility & Clamping Range
The JTBY-160PV-305 square-hole laser chuck is designed to clamp a variety of tube and profile shapes used in tube laser cutting applications. Its square-hole structure makes it suitable for mixed production where round tubes, square tubes and selected structural profiles need to be processed on the same machine.
Round Tubes
Supports round tubes with diameters from Ø8 to Ø165 mm. Workpieces outside this diameter range require a different chuck size or a specially engineered clamping solution.
Square Tubes
Supports square tubes up to 165 × 165 mm, making the chuck suitable for common square-section tube cutting applications.
I-Beams and Channel Steel
The chuck can accommodate compatible I-beams and channel steel up to No. 10, provided that the profile geometry fits within the available jaw clamping range.
Special-Shaped Profiles
Special-shaped tubes and profiles can be clamped within the effective jaw range, with custom auxiliary jaws available for irregular workpieces. This provides greater flexibility for non-standard profile processing.
Clamping Limitations
The standard chuck configuration is not recommended when the workpiece exceeds the specified 165 mm size range, falls outside the effective jaw contact area, or causes the combined load on the front and rear chucks to exceed 120 kg. In these cases, a larger laser chuck model or a customized jaw configuration should be selected.
Front & Rear Chuck Configuration
The JTBY-160PV-305 laser chuck set combines a front chuck and rear chuck for integration with tube laser cutting machines, providing a complete clamping configuration for workpiece positioning and support during cutting.
Front Chuck
The front chuck features a 110 flange interface and a 1:4 transmission ratio, providing defined mechanical parameters for machine mounting and drive-system matching.
Rear Chuck
The rear chuck is available with a 90 / 110 flange interface and uses a 1:3 transmission ratio, allowing the chuck configuration to be matched to different machine structures and installation requirements.
Machine Integration
With clearly defined front and rear chuck interfaces, the tube laser cutting chuck system can be integrated into compatible CNC laser tube cutting equipment. The combined load capacity of the two chucks is up to 120 kg.
For machine builders or retrofit projects, mounting dimensions, drive configuration and workpiece requirements should be confirmed before selecting the final chuck configuration.
Typical Applications
The JTBY-160PV-305 laser chuck is designed for tube laser cutting applications that require flexible clamping of different workpiece shapes and sizes.
Is This the Right Chuck for Your Machine?
The JTBY-160PV-305 laser chuck is a good fit for tube laser cutting machines that process medium-size tubes and profiles within the specified clamping and load range.
Choose This Model If:
Your round tubes are between Ø8 and Ø165 mm
Your square tubes are up to 165 × 165 mm
You process a mix of round tubes, square tubes and structural profiles
Your application requires a front and rear laser chuck set
The combined workpiece load does not exceed 120 kg
You need optional custom auxiliary jaws for irregular or special-shaped profiles
Consider Another Chuck Model If:
A larger or different laser chuck for tube cutting machines should be considered if the workpiece exceeds the 165 mm clamping range, exceeds the rated load capacity, or requires a jaw configuration outside the standard working range.
For machine integration, confirm the workpiece size, shape, weight, mounting interface and processing requirements before selecting the final chuck configuration.
Engineering Validation & Quality Control
The JTBY-160PV-305 laser chuck is manufactured and inspected with a focus on dimensional accuracy, assembly consistency and reliable integration with tube laser cutting machines.
Dimensional & Interface Inspection
Key dimensions and mounting interfaces, including the front and rear chuck flange specifications, are checked to ensure compatibility with the intended machine configuration.
Assembly & Functional Verification
The front and rear chucks are checked for proper assembly, jaw movement and transmission operation before delivery, helping ensure stable clamping performance during tube and profile processing.
Quality Documentation & Traceability
Technical drawings, dimensional information and relevant inspection records can be provided according to project requirements. For OEM machine builders and customized applications, critical mounting and workpiece parameters can also be confirmed before production.
For special profiles or customized jaw configurations, the workpiece dimensions and clamping requirements should be reviewed in advance to ensure the selected laser chuck system matches the application.
FAQs
Is the JTBY-160PV-305 suitable for mixed tube production?
Yes. Its square-hole design is suitable for production involving round tubes, square tubes and compatible structural profiles, making it a practical option for manufacturers processing multiple workpiece types on the same tube laser cutting machine.
When are custom auxiliary jaws required?
Custom auxiliary jaws are recommended when special-shaped or irregular profiles cannot be securely clamped within the effective range of the standard jaws. Jaw design can be matched to the workpiece geometry and clamping requirements.
What should be checked before integrating the chuck into a laser cutting machine?
Before installation, confirm the mounting interface, flange specification, transmission ratio, workpiece size, workpiece weight and machine configuration to ensure the laser chuck matches the equipment design.
What information is needed to select the correct laser chuck?
For accurate model selection, provide the workpiece shape, minimum and maximum dimensions, maximum weight, laser cutting machine configuration, mounting requirements and drawings of any special profiles.
