Product Number: 3020MM20-70
Firm-grade vibration control demands a mount that holds position under load rather than absorbing it, and the 3020MM20-70 male-male bobbin mount is built precisely for that role. With a 30 mm diameter, 20 mm height, M8 x 20 mm threaded studs on both faces, a maximum load rating of 51.0 kg and a minimal deflection of only 1.6 mm, this 70 Shore A unit is the highest-load, lowest-movement option in the 30x20 mm male-male bobbin family, suited to applications where positional control and shock resistance matter as much as vibration attenuation. The rubber-to-metal bonded construction combines a firm 70 Shore A natural rubber element with steel end-plates, giving a robust assembly that can be loaded in shear, compression, or a combination of both. The firm durometer means the mount resists displacement under dynamic shock and sustained load, making it the appropriate grade where machinery must be held reliably in place rather than allowed to float freely under lighter loads. Applications for this grade include diesel engine mountings, generator sets, heavy industrial machinery and equipment, and automotive exhaust mountings where firm restraint is required. It is equally relevant in construction and off-highway, agriculture, power generation, marine, and railway and mass transit environments, wherever equipment imposes sustained or impact loads that softer grades could not carry without excessive movement. Custom metals (stainless steel) and oil-resistant or high-temperature rubber compounds are available on request for specialist duty cycles. This mount is part of a wider 30x20 mm male-male bobbin range.

A. The mount has a 30 mm outer diameter and 20 mm height (D x H: 30 x 20), with M8 x 20 mm threaded studs on both faces. The maximum load rating is 51.0 kg and the deflection at rated load is 1.6 mm.
A. A 70 Shore A rating places this mount at the firm end of the range. It carries higher loads with less movement — the 1.6 mm deflection figure reflects that stiffness. This grade prioritises positional control and resistance to shock and impact over the greater isolation travel available from softer 45 or 60 Shore grades.
A. The 70 Shore A grade is appropriate for diesel engines, generator sets, heavy industrial machinery, automotive exhaust mountings, and equipment in construction, off-highway, agriculture, marine, and railway environments where sustained or impact loads require firm restraint rather than soft isolation.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is installed within a machine or structure.
A. Yes. The same geometry is available in 45 Shore A (3020MM20-45) for maximum deflection and isolation at lower loads, and in 60 Shore A (3020MM20-60) as a mid-range option. Select the grade that matches your load and isolation requirements.
A. Yes. Stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, alongside additional and custom sizes.
