Product Number: 3040MF20-70
Variations
Rated at a maximum load of 37.0 kg with a controlled deflection of just 3.6 mm, the 3040MF20-70 is a 70 Shore A male-female bobbin anti-vibration mount engineered for installations where the mounted item must be held firmly with minimal movement under heavier load or sudden shock. The 30 mm diameter by 40 mm height rubber element is bonded to metal end fittings comprising an M8 x 20 mm male stud and an M8 female thread, providing secure, direct attachment in confined or compact mounting arrangements. The firm 70 Shore A rubber compound delivers the highest load-bearing capacity within the 30x40 mm male-female bobbin range, making it the appropriate grade where vibration isolation must be balanced against positional restraint. Rubber-to-metal bonded construction throughout ensures consistent load transfer and long service life. The mount may be used in shear, compression, or a combination of both, giving installation flexibility across a range of fixings and orientations. At 70 Shore A, this grade is particularly suited to heavier plant items, shock-prone equipment, and applications requiring firm retention of the mounted assembly. Appropriate uses include diesel engine mountings, generator sets, industrial machinery and equipment, and exhaust mountings where load demands and impact forces call for a harder rubber compound. The mount also serves agricultural, marine, automotive, and construction and off-highway environments.

A. The 3040MF20-70 has a maximum load rating of 37.0 kg and a deflection of 3.6 mm. The 70 Shore A rubber compound provides the firmest grade in this size range, giving the highest load capacity with the least movement.
A. The male stud is M8 x 20 mm and the female threaded socket is M8, allowing direct bolted attachment at both ends.
A. The rubber element measures 30 mm in diameter by 40 mm in height (D x H: 30 x 40 mm).
A. Shore A hardness determines the balance between load capacity and deflection. The 70 Shore A grade carries the highest load with least movement, making it appropriate for heavier equipment, shock-prone machinery, and installations requiring firm positional restraint. Softer grades — 45 Shore A (3040MF20-45) and 60 Shore A (3040MF20-60) — offer greater deflection and improved isolation at lower loads.
A. The mount may be loaded in shear, compression, or a combination of both, providing flexibility across different installation configurations.
A. At 70 Shore A, this mount is suited to diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and similar applications in automotive, agricultural, marine, and construction and off-highway environments where heavier loads or impact forces are present.
A. Yes — stainless steel metal parts and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
