Why Your Robotiq Gripper May Show Surface Marks or Color Variations

Understand the normal cosmetic differences in gripper finishes and rubber components

Context

This article explains why some Robotiq grippers may show minor surface scratches or slight color differences on the rubber fingertips. These characteristics are expected and do not indicate a defect or affect the product’s performance.

 

Anodized Gripper Body

  • Robotiq grippers use an anodized aluminum finish, not paint.

  • Anodizing is an electrochemical process that increases corrosion resistance and durability.

  • Unlike paint, anodizing does not produce a uniform cosmetic layer.

  • Minor surface marks or scratches can appear during handling or assembly.

  • These do not affect the gripper’s strength, functionality, or lifespan.

Rubber Fingertip Color Variations

  • Rubber fingertips may show slight color inconsistencies.

  • This is due to natural differences in rubber material and the molding process.

  • These variations are normal and have no impact on gripping performance or durability.

When to Contact Support

  • If you see deep damage, missing parts, or functional issues, contact Robotiq Support.

  • Cosmetic differences alone do not require replacement or service.

 

Conclusion

Surface marks on the gripper body and color variation on rubber tips are both normal and expected. These features are part of the manufacturing process and do not impact performance or reliability.
