Sorbothane Pad Set 60D AEG

Brief History

Sorbothane is a material invented in 1982 out of the need for a material with good mechanical shock absorption properties. Sorbothane is a blend of materials with elastic properties similar to those of silicone, rubber, and other soft plastic polymers. This material is successfully used worldwide in various fields such as aerospace engineering, construction, and sports. Manufactured in various shapes, thicknesses, and hardnesses, Sorbothane effectively absorbs most mechanical shocks.

Description

This Sorbothane pad is used to dampen the shock between the piston head and the cylinder head in AEG replicas, thus extending the lifespan of the entire assembly. The front end of the gearbox casing will break much less easily, and the chances of cracking both the piston head and the cylinder head are reduced. The pad is made from Sorbothane and polyurethane. The polyurethane exists to protect the integrity of the Sorbothane surface.

Due to its dimensions, this pad serves a dual purpose. The first role is to absorb mechanical shocks, while the second is to adjust the angle of engagement of the piston by the sector gear, known as AOE, Angle Of Engagement.

In most cases, this engagement angle is incorrect, with the sector gear pulling the piston at the wrong angle, wearing down the first tooth and potentially breaking it over time. Using pistons with all-metal teeth also carries the risk of wearing down the first tooth of the gear, eventually leading to its breakage.
By applying the Sorbo-pad on the cylinder head, this engagement angle is corrected, which is valid in most cases, optimizing the engagement of the piston by the sector gear.
However, great care must be taken during installation. The last teeth of the piston must be configured correctly. The second tooth of the piston must be completely removed, the third reduced by half, and the fourth reduced by 1/4 of its original size. The pad is mounted on the surface of the cylinder head after removing the original rubber. It is secured with super glue. (The Sorbo-pad does not come with adhesive)

This Sorbo-pad is compatible with version 2 and 3 gearbox for AEG replicas.

The package is delivered with 4 thicknesses for optimal adjustment:

• 3.5 mm
• 4.2 mm
• 5.8 mm
• 7.4 mm

The manufacturer recommends using 60D Sorbothane with the following springs:

• For standard replicas with springs up to 130 m/s
• For high rate of fire replicas and SAW type replicas with springs up to 120 m/s
• For DMR replicas with springs up to 140 m/s
