M6 M8 M10 Thread Sizes Double Male Stud Cylindrical Rubber Vibration Isolation Mount and Rubber Isolator Mount
Product Details
Anti-Vibration Rubber Mount
,Oil-Resistant NR Compound
,Galvanised Steel Inserts
This noise-reduction compression-mount rubber isolator is purpose-built for air compressors, where a rigid machine-to-floor connection would otherwise radiate a constant drone through the building. The mount works in pure compression, so the compressor load passes straight down through the rubber element and the isolation behaviour stays predictable from the moment it is fitted. With no shear or tension components to account for, the design is simple, robust and largely maintenance-free once the machine has been levelled.
Loading the rubber in compression gives a stiff, stable support with a very predictable vertical spring rate. The natural frequency can be set low enough to avoid resonance with the compressor's running speed.
Operators get quieter operation, less fatigue cracking in pipework and longer bearing life from a single, inexpensive change. Removing structure-borne noise at source also shields neighbours and employees from the low-frequency rumble that rigid mounts transmit.

Q: Will fitting this isolator actually cut compressor noise?
Yes — the rubber element mainly removes structure-borne noise, the low drone that travels through a rigid floor or frame.
Q: Is compression mounting better than shear for a compressor?
A compression design avoids the tension that shear mounts can impose, which suits the steady downward weight of a compressor.
Q: Will oil damage the rubber?
The compound is chosen to resist oil mist and ageing, so the compressor isolator keeps working in an oily environment.
Q: How do I pick the load capacity?
Send the total weight and foot count and we will calculate the correct load rating for you.
Additional Notes
Sizing the M6 M8 M10 Thread Sizes Double Male Stud Cylindrical Rubber Vibration Isolation Mount and Rubber Isolator Mount: begin with the point load at each support, then check the running speed. The right rubber grade keeps the natural frequency clear of the machine speed, which is what avoids resonance and cracked mounts.
- Suited to equipment running above 1200 rpm, where plain pads fall short.
- Adhesion of about 40 kg/cm2 keeps the rubber and steel firmly bonded.
- A temperature window of -40 C to +80 C covers cold stores and warm plant rooms.
Because the rubber carries load in two directions at once, the same body can be tuned for a light fan or a heavier machine simply by changing the compound hardness. That is why the load rating and the running speed matter more than the mount's size on its own. If you can share a mounting drawing or the bolt centres, we will match the rating and thread to suit your base without guesswork.
Quick Q&A
Q: How many mounts does a machine need?
A: Typically one per support point; send your layout for a count and rating.
