Friction Inserts
Achieve a higher coefficient of friction in critical connections in heavy machinery, gearboxes, and structures
Friction Inserts: friction increase materials for high-performance bolted Joints
When design limits are reached, increasing friction becomes the key to unlocking higher performance. A higher coefficient of friction allows bolted joints to transmit more torque without slipping.
Freudenberg Friction Inserts provide a reliable, high friction coefficient solution for engineers and specialists dealing with critical bolted connections in heavy-duty and industrial environments.

What is friction increase?
Friction increase is the process of raising the static friction coefficient between two surfaces. This allows higher load transmission without movement. In industrial systems, this prevents:
- Slip in bolted joints
- Structural instability
- Mechanical failures
Friction Inserts are a friction increase solution using a micro-interlock mechanism. Diamonds embedded on a flexible carrier penetrate both joining surfaces under load, increasing friction significantly. This solution combines:
- High friction performance
- Tolerance neutrality
- Ease of integration
The result is a design tool for engineers, not just a corrective measure.

How do Freudenberg Friction Inserts differentiate from other friction enhancement solutions?
Friction Inserts stand out by combining high friction, no tolerance impact, and flexible integration. Other solutions like metal shims or coatings typically require trade-offs between performance, consistency, and manufacturability.
Frequently Asked Questions about Friction Inserts in industrial environments
It is advisable to increase friction in a connection when there is a problem with the transmission of forces or when there is a risk that bolts could become loose.
Freudenberg Friction Inserts work well with thin coatings like e-coatings. We can test their compatibility with other corrosion coating systems.
Freudenberg Friction Inserts utilize a mechanical interlocking mechanism of the diamonds into the surfaces, ensuring that oil and grease do not affect their performance.
Freudenberg Friction Inserts are packaged for transportation in a way that ensures they remain securely in place. As Friction Inserts use adhesives, they must not be stored in temperatures over 40°C or in direct sunlight.
