Isolator Sandwich Mounts (SL Series)

The ISOLOSS SL series are the highest damped E-A-R elastomers, capable of loss factors above 2. There are multiple Type A durometers available including SL-20300 (19), SL-35300 (30), SL-50300 (45), and SL-60300 (56).

E-A-R™ vibration isolation sandwich mounts combine highly damped elastomeric materials in overmolded standoff designs. These isolators are available in multiple configurations: male to male (MM), male to female (MF), male to blank (MB), and female to blank (FB). Each isolator is constructed of compression molded damping elastomer bonded to steel inserts.
