Rated at a maximum load of 400 kg with a controlled deflection of just 3.4 mm, the 7540FF12-70 is the firm-grade member of the 75×40 mm female-female bobbin mount family, engineered for applications where positional stability under heavy load, shock and impact take priority over maximum deflection travel. Its 70 Shore A rubber element delivers the least movement in the range, making it the appropriate choice wherever the mounted component must be held firmly against dynamic forces or sudden impulse loads. Constructed with rubber-to-metal bonding throughout, the mount accepts loading in shear, compression or a combination of both, providing versatility across installation geometries. The female-female thread configuration (M12 both ends) simplifies direct bolted attachment without additional hardware. As with the broader family, stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for demanding service environments. Typical applications for a firm 70 Shore A grade at this size include diesel engine and generator set installations where mass is high and movement budgets are tight, exhaust mounting systems subject to thermal cycling and impulse loading, and industrial machinery subject to shock loads in construction, off-highway, agricultural, marine, railway and power generation settings. The mount also suits instrument and equipment enclosures where vibration transmission must be attenuated without permitting significant relative displacement. This listing covers the 70 Shore A variant. Softer isolation grades in the same 75×40 mm M12 geometry are available as 7540FF12-45 and 7540FF12-60.

A. The 7540FF12-70 is rated to a maximum load of 400 kg with a deflection of 3.4 mm under that load.
A. At 70 Shore A, this is the firm grade in the 75×40 mm family. Harder rubber carries higher loads with less movement, making it suited to heavy-load, shock and impact duty where positional stability is critical rather than maximum vibration isolation.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility across different installation orientations.
A. The mount has a female-female thread configuration with M12 threads, allowing direct bolted attachment at both ends.
A. Suitable applications include diesel engines, generator sets, exhaust mountings, air-conditioning units, industrial machinery and equipment, and instruments across construction and off-highway, agricultural, marine, railway, power generation, automotive and military and defence sectors.
A. Yes — softer grades are available as 7540FF12-45 (45 Shore A) and 7540FF12-60 (60 Shore A) for applications requiring greater deflection and improved isolation at lower loads.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
