Aluminum Cross Pipe Clamp – Optical Axis Shaft Fixing Connector

Aluminum Alloy Cross Pipe Clamp – Precision Axial Fixing Connector

This aluminum alloy cross tube clamp is a versatile and durable fastening component designed for DIY builds, linear motion systems, and precision mechanical assemblies. Whether you're constructing a guide rail setup, a robotic arm frame, or an automation jig, this clip-style connector delivers rock-solid axial and radial positioning with effortless installation. Made in China.

Key Features

• Axial Shaft Fixation: Mounts firmly to one side of a rotating or sliding shaft to keep components locked in position during operation.
• Guide Shaft Stop Block: Ideal for use at one end of a linear guide shaft, acting as a precise stop block for linear motion mechanisms.
• Adjustable Positioning: Clamp both ends of a shaft section to define and fine-tune the axial position of any mounted part.
• Screw-Lock Clamping: The open-end screw design tightens securely around the shaft without marring or damaging the shaft surface — protecting both the clamp and the workpiece.
• Aluminum Alloy Construction: Lightweight yet strong, with natural corrosion resistance and long service life.
• Wide Application Range: Suitable for semiconductor manufacturing equipment, PCB/IC assembly machines, robotic arms, precision measurement instruments, office automation devices, and large linear sliding systems.

Frequently Asked Questions

Q: What shaft or tube diameter does this aluminum cross clamp fit?

A: The clamp size is as shown in the product images. Please refer to the listing photos for exact bore diameter specifications. For the best fit, measure your optical axis or guide shaft diameter before ordering.

Q: Will this clamp damage or scratch the shaft surface when tightened?

A: No — the open-end screw-lock design distributes clamping force evenly around the shaft, securing it firmly without gouging or marring the shaft surface. This protects both your shaft and the clamp itself.

Q: Can this clamp be used in both rotational and linear motion applications?

A: Yes. This cross connector is designed to handle axial fixation for both rotating shaft components and linear guide rail stop-block applications, making it highly versatile for a wide range of DIY and industrial assembly projects.

Q: Is this clamp suitable for outdoor or humid environments?

A: The aluminum alloy construction offers natural corrosion and rust resistance, making it suitable for moderately humid environments. However, for heavy outdoor exposure, consider additional protective measures.
