Product Number: 4020MM23-70
Variations
Carrying a maximum load of 106.0 kg with a minimal deflection of just 1.6 mm, the 4020MM23-70 is a 40 x 20 mm male-male anti-vibration bobbin mount with M8 x 23 mm threaded studs rated at 70 Shore A, the firmest grade in this geometry, built to hold equipment securely under sustained heavy loading and sudden shock or impact. At 70 Shore A, this rubber-to-metal bonded mount prioritises positional control over compliance. The stiff rubber element resists movement under load, making it the appropriate choice where excessive deflection would compromise alignment, where mass must be firmly restrained, or where impact and shock inputs demand a mount that does not yield. The bobbin design accommodates loading in shear, compression, or a combination of both, offering installation flexibility across many structural configurations. With a 40 mm outer diameter and 20 mm height, the 4020MM23-70 suits machinery applications where space envelopes are constrained but load demands are not. Typical end uses drawn from the family application range include diesel engines, generator sets, industrial machinery and equipment, and heavy-duty automotive and off-highway installations, industries where vibration control must coexist with positive mechanical restraint. Custom stainless steel hardware and oil-resistant or high-temperature rubber compounds are available on request for specialist environments. This mount is part of a broader male-male bobbin range.

A. The mount has an outer diameter of 40 mm and a height of 20 mm, with M8 x 23 mm male threaded studs at each end.
A. The 4020MM23-70 is rated to a maximum load of 106.0 kg with a deflection of 1.6 mm, making it the highest-load, least-movement option in the 40 x 20 mm male-male bobbin range.
A. A 70 Shore A hardness delivers the highest load resistance and the least deflection within this geometry. Harder grades are appropriate where equipment must be held firmly in position, where shock and impact loads are present, or where excessive movement would compromise alignment or structural integrity. Softer 45 Shore A and 60 Shore A versions (4020MM23-45 and 4020MM23-60) are available if greater isolation or compliance is required.
A. The mount may be loaded in shear, compression, or a combination of both, providing flexibility in how it is oriented and installed within a given assembly.
A. The male-male bobbin family is used across diesel engines, generator sets, industrial machinery and equipment, air-conditioning units, exhaust mountings, and automotive and off-highway applications, as well as in agriculture, power generation, marine, railway and mass transit, and military and defence.
A. Yes. Stainless steel hardware and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. The range includes 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44, covering a broad spread of dimensional and load requirements.
