Spring Mount

- As an enclosed spring mount, it has the spring between upper and bottom housings. An anchor hole is on the bottom housing and the tap is on the top housing, which allows level control of the bolt with a level bolt and nut to be used. Plus, the spring cap with a bolt guided hole is at the top of the spring to distribute the load transferred from the level bolt and the anti-frictioner is attached between upper and bottom housings, which somewhat reduces attenuation and friction caused by left-right and top- down relative displacement when the equipment is running. There is a CR pad attached on the bottom of the bottom housing to compensate disadvantages of the spring transferring high frequency due to a kind of surging effect. 

- As an enclosed spring mount, it has the same features and intended purpose as the SMB type, but is equipped with the spring having a static deflection of 50 mm. It is used when equipment like air conditioners and fans installed on a group floor of the building need to be kept quite when running.
