Q 1. What are the key dimensions and thread sizes for the 3020MF20-70?

A. The mount measures 30 mm diameter by 20 mm height. The male stud is M8 with a 20 mm stud length (d1 x L: M8 x 20) and the female thread is M8 (d2: M8).

Q 2. What is the maximum load capacity and deflection of this mount?

A. The 3020MF20-70 has a maximum load rating of 53.0 kg and a deflection of 1.6 mm, reflecting the firm 70 Shore A grade's emphasis on load retention and minimal movement.

Q 3. Why choose a 70 Shore A grade over softer hardness grades?

A. At 70 Shore A, this grade carries higher loads with less movement than softer grades. It is the appropriate choice when components must be held firmly in place under sustained load, shock, or repeated impact rather than maximising vibration isolation.

Q 4. In which directions can this bobbin mount be loaded?

A. The mount may be loaded in shear, compression, or a combination of both, providing installation flexibility across a range of mounting orientations.

Q 5. What applications is the 3020MF20-70 suited to?

A. Typical applications include diesel engines, generator sets, industrial machinery and equipment, exhaust mountings, and air-conditioning units. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.

Q 6. Are alternative hardness grades available in the same 30 x 20 mm male-female size?

A. Yes — the 30 x 20 mm male-female family is also available in 45 Shore A (SKU: 3020MF20-45) and 60 Shore A (SKU: 3020MF20-60) for lighter loads or applications requiring greater deflection and isolation.

Q 7. Are custom materials or non-standard sizes available?

A. Stainless steel fittings and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
