Revolutionizing O-Ring Installation
The Future of Automated O-Ring Installation
In modern manufacturing, flexibility and precision aren’t optional, they’re essential. That’s why AIS developed the Variable Robotic Module (VRM), the most adaptable robotic O-ring installation solution available today. Built to work with SCARA or 6-axis robots, and designed around AIS’s proven radial stretch method, the VRM brings a new level of accuracy, speed, and placement freedom to automated seal installation.
The VRM is not a standalone tool, it is engineered to integrate directly with the AIS ASP-1 O-ring installation machine, forming a fully synchronized system for advanced O-ring handling and placement.
Unmatched Flexibility for Complex O-Ring Placement
The VRM uses a pneumatically controlled actuator that can tilt, pivot, or rotate up to 180°, and its hollow design allows O-rings to be installed at multiple depths on the same part.
This gives robotic systems the ability to install O-rings:
- at almost any angle
- on external surfaces at varying depths
- at any reachable position on the part
This level of adaptability eliminates many of the constraints that traditionally limit seal-assembly automation.
Whether your part geometry is simple or highly complex, the VRM allows your robot to place each O-ring exactly where it needs to go.
Precision You Can Count On
By pairing the VRM with the AIS ASP-1, manufacturers gain an installation process that is both fast and dependable. The ASP-1’s consistent radial stretch ensures:
-
proper O-ring expansion,
-
reduced installation damage,
-
tight, repeatable seal placement,
-
long-term O-ring integrity,
-
fewer rejects and rework events.
Cycle rates can reach up to 45 installations per minute (2,700 per hour) while maintaining the precision that AIS is known for across industries requiring medical-grade, automotive-grade, or industrial-grade reliability.
Engineered for Seamless Robotic Integration
The VRM is built to slot directly into:
-
existing robotic cells, or
-
new automation builds looking for a flexible O-ring installation module.
Once integrated, the robot can rotate or tilt the VRM to the required angle, and place the O-ring on the part without human intervention or manual handling.
This design:
-
reduces bottlenecks,
-
shortens cycle times,
-
improves workflow consistency, and
-
supports more advanced assembly sequences.
The VRM essentially turns your robot into a full-coverage O-ring installer, capable of reaching positions and orientations that fixed tooling can’t match.
A Game-Changer for Modern Automated Assembly
Manufacturers across plastics, automotive, medical, industrial, aerospace, and consumer product sectors are seeking ways to automate O-ring installations that previously required manual assistance. The VRM-ASP-1 combination delivers:
-
high precision, even on intricate geometries
-
high throughput, without sacrificing accuracy
-
reduced labor costs and fewer ergonomic risks
-
repeatable quality, shift after shift
-
increased design freedom, allowing engineers to optimize parts rather than design around installation constraints
The VRM features adjustable, pre-set pneumatic rotation from 90° down to 180° outward. This setup lets your automation cell match your part geometry without any on-the-fly adjustments.
See What True Flexibility Looks Like
The Variable Robotic Module, paired with the AIS ASP-1, represents the next evolution in automated O-ring installation:
-
fewer constraints
-
fewer damaged seals
-
fewer limitations on your part design
If your production line needs faster cycles, improved seal integrity, and a more capable robotic assembly cell, the VRM delivers a scalable, flexible, and proven solution.
