Product Number: 4030MM25-70
Variations
Engineered to hold firm under demanding conditions, the 4030MM25-70 is a 40x30mm male-male anti-vibration bobbin mount with M10x25 threads and a 70 Shore A rubber hardness grade, the firmest option in this geometry and the right choice when maximum load capacity and minimal deflection are the priorities. With a maximum load rating of 87.0 kg and a deflection of just 2.6 mm, this mount is built for applications where controlled restraint and structural rigidity matter as much as vibration attenuation. Rubber-to-metal bonded construction gives the 4030MM25-70 the integrity to operate effectively in shear, compression or a combination of both. The firm 70 Shore A compound resists movement under shock and impact, making it particularly suited to heavier plant and equipment where a softer grade would allow excessive displacement. As with all mounts in this family, the rubber compound is available in oil-resistant and high-temperature variants on request, and stainless steel hardware can be specified for corrosive environments. This mount serves industries including power generation, construction and off-highway, marine, agriculture, and automotive, anywhere diesel engines, generator sets, industrial machinery or equipment must be secured and isolated from structure-borne vibration simultaneously. The combination of an M10 thread, a compact 40x30mm body and a 70 Shore A rating makes it a practical fit for mid-range machinery mounting where load exceeds what lighter grades can reliably carry. This mount is one of several sizes and grades available.

A. This mount has a maximum load rating of 87.0 kg and a deflection of 2.6 mm.
A. The outer body measures 40 mm diameter by 30 mm height (D x H: 40x30). The threaded stud is M10 with a 25 mm length (d x L: M10x25).
A. A 70 Shore A rating is the firmest grade in this geometry. It carries higher loads with less movement, making it suited to heavier equipment, shock and impact loading, and applications where the mounted item must be held firmly in position rather than allowed to deflect freely.
A. The mount can be loaded in shear, compression or a combination of both.
A. This mount is suited to applications including diesel engines, generator sets, air-conditioning units, exhaust mountings, instruments, and industrial machinery and equipment. Industries served include power generation, construction and off-highway, agriculture, marine, automotive, and railway and mass transit.
A. Yes — oil-resistant and high-temperature rubber compounds, stainless steel hardware, and additional or custom sizes are available on request.
A. Yes. The same 40x30mm M10x25 geometry is available in 45 Shore A (4030MM25-45) and 60 Shore A (4030MM25-60). Additional sizes in the wider range include 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44.
