Description
PM (foot/male) cylindrical rubber anti-vibration mounts: a rubber cylinder with a flat bearing face (foot) and a threaded stud on the other side. They isolate the machine from its base, absorb vibration and noise and cushion shocks; it works as a foot: it rests on the floor and the stud screws into the underside of the machine. Available in 34 sizes, with M4, M6, M8, M10, M12 threads.
- TypePM (foot/male)
- Diametersfrom 15 to 75 mm
- ThreadsM4 · M6 · M8 · M10 · M12
- Dimensions34
Features
- Rubber vulcanised to the metal parts: a single piece, with no glued joints to come apart
- Reduces vibration transmitted to floors, structures and electrical panels
- Lowers noise and protects the machine from shocks
- Quick mounting with standard screws or nuts
Typical applications
Operating conditions
| Load | Works best in compression, with the weight spread over all mounts |
|---|---|
| Shear and tension | Only permitted to a limited extent: under tension the rubber can come away |
| Environment | Dry; rubber does not tolerate oils, solvents, ozone or direct sunlight |
| Temperature | Environment: avoid contact with hot parts of the machine |
Advantages
- Simple and inexpensive
- Absorbs vibration and noise well
- Mounts with standard fasteners
Limitations
- Limited elastic travel
- Not suitable for tensile loads
- Rubber ages with oils, ozone and UV rays
How to read the size
In the "Dimensions" menu you will find the diameter × height of the rubber cylinder (e.g. 20x20 = Ø 20 mm, 20 mm high); in the "Thread" menu, the thread and its length (e.g. M6x6 = M6 thread, 6 mm long).
Technician's tipDivide the weight of the machine by the number of mounting points and choose a mount suited to that load; use the same model at every point, otherwise the machine tilts and vibrates more.
