Maus 5R/70 & 5R/71 Tube Expander Series

Five-Roller Systems for Thin-Walled & Sensitive Tubing

Superior Stress Distribution

The Maus 5R/70 and 5R/71 series feature a specialized five-roller design that distributes expansion forces evenly around the tube circumference. This is critical for thin-walled tubes and sensitive materials such as titanium or stainless steel, where conventional 3-roller systems might cause excessive stress or unwanted distortion.

Key Advantages

• Reduced Distortion: 5-roller setup minimizes local stress points.
• Precise Depth: Adjustable collars allow for exact expansion seating.
• System Ready: Fully compatible with torque-controlled pneumatic or electric drives.

Expert Insight: When working with thin-wall tubing in heat exchangers, the five-roller configuration is your best defense against tube wall deformation. It ensures that the expansion force is applied in smaller, more frequent increments, resulting in a superior, leak-free seal without damaging the tube's structural integrity.
