Cup Spring Mounts

Easyflex EFCUS Type Spring Isolators are highly effective for control of both high and low frequency vibration produced by reciprocating air or refrigeration compressors, pumps, packaged air handling and air conditioning equipment, centrifugal and axial fans, internal combustion engines, etc. The Type Spring Isolators are free standing and laterally stable spring isolators. The coils are designed with an excellent ratio between the coil outer diameter and operating height, ensuring lateral stability. In all of our designs, this ratio is a minimum of 0.80 and many of our springs have approximately a 1:1 ratio. In addition, our coils are designed with low operating stresses, thus ensuring a long operating life for the isolator. The EFCUS Type Spring Isolators also feature weldless construction. The spring coils are not welded to steel plates. Instead, the EFCUS Type Spring Isolators are assembled to elastomeric cups and steel plate bases with two mounting holes for attachment to structure – providing durability and flexibility. The series also include a built-in leveling device for simplified installation. The product incorporates a color-coded steel spring for ease of identification and inspection in the field. All of our open spring isolators have leveling capability and include a bolt hole in the bottom cup.
