RoHS

Rubber elasticity protects the mounting device from vibration and impact: Anti-vibration rubber protects the mounting device from vibration and impact with its rubber elasticity.
It also reduces the transmission of vibrations from motors, fans, etc., and prevents solid noise generated from panel covers, etc.

Performance/Features

1. The elastic structure absorbs vibrations and shocks and reduces the generation of solid sound.

2. Labor saving can be achieved

3. Can be easily tightened with a screwdriver by working on one side

4. Excellent sealing effect against liquids and gases

Precautions for use

How to use

There are two ways to use Anti-vibration rubber: one for simple fixation and one for vibration isolation. In either case, the fastening method is the same. Insert Anti-vibration rubber from one side into the designated pilot hole and screw in the screw to expand the rubber sleeve, making it easy to fasten.
In this case, the self-tightening action of Anti-vibration rubber acts as a lock washer and a lock nut is not required.
Refer to the table above for plate thickness, prepared hole diameter, and tightening torque.
