Product Number: 4030FF08-45
Variations
Sensitive installations and lighter equipment demand a mount engineered for maximum vibration isolation rather than load restraint, and that is precisely where the 4030FF08-45 Female-Female Bobbin Mount excels. At 40 mm diameter by 30 mm height with M8 female threads at both ends, this soft 45 Shore A rubber-to-metal bonded mount is rated to a maximum load of 35.0 kg and delivers 2.6 mm of deflection under that load, figures that place it firmly in the light-duty, high-isolation band of the range. The 45 Shore A hardness grade is the softest available in this geometry, and softer rubber provides greater deflection and correspondingly better vibration isolation, particularly at lower frequencies. This makes the 4030FF08-45 the preferred choice where isolating the structure from the source matters more than limiting movement, for example, on precision instruments, acoustic-sensitive enclosures, small generator sets, and lightly loaded air-conditioning units where transmitted vibration degrades performance or comfort. Rubber-to-metal bonded construction ensures a reliable mechanical connection while the compliant rubber element absorbs and attenuates vibration energy before it reaches the surrounding structure. The mount may be loaded in shear, compression, or a combination of both, offering flexibility in installation orientation. Female threads at both ends allow direct through-bolting without additional hardware, simplifying fitment in compact assemblies. The rubber compound is suited to general industrial service; oil-resistant and high-temperature rubber variants, stainless steel metalwork, and custom sizes are available on request. This SKU forms part of a broader Female-Female Bobbin Mount family.

A. The mount measures 40 mm in diameter by 30 mm in height, with M8 female threads at both ends. It has a maximum load rating of 35.0 kg and a deflection of 2.6 mm at that load.
A. Softer rubber at 45 Shore A provides greater deflection and better vibration isolation, particularly at lower frequencies and lighter loads. It is suited to sensitive or precision equipment where isolating vibration from the structure is the priority, rather than limiting movement under heavy load.
A. The 45 Shore A grade is appropriate for lightly loaded or vibration-sensitive installations including instruments, small generator sets, lightly loaded air-conditioning units, and similar applications where lower-frequency vibration isolation is the primary requirement.
A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is installed within an assembly.
A. Yes. Oil-resistant and high-temperature rubber compounds, stainless steel metalwork, and custom sizes are available on request.
A. In the same 40x30 mm M8 geometry, a 60 Shore A medium grade (4030FF08-60) and a 70 Shore A firm grade (4030FF08-70) are available. Larger Female-Female Bobbins include 100100FF16, 10040FF16, 10045FF16, 10050FF16, 10055FF16, and 10060FF16.
