Product Number: 4040FF08-45
Variations
Where isolation takes priority over restraint, the 4040FF08-45 female-female bobbin mount delivers maximum vibration absorption for lighter or mechanically sensitive installations. At 45 Shore A, the softest grade in this 40×40 mm M8 thread family. The rubber compound yields a deflection of 3.6 mm under its maximum rated load of 31.0 kg, giving this mount a compliance profile suited to equipment whose performance is compromised by transmitted vibration rather than by the need to withstand high shock loading. Rubber-to-metal bonded construction gives the 4040FF08-45 its durability in service, while the female-female thread configuration (M8 both ends) simplifies installation directly between a mounting bracket and the equipment base plate without additional hardware. The mount may be loaded in shear, compression, or a combination of both, making it adaptable across a range of orientations and installation geometries. Custom variants in oil-resistant or high-temperature rubbers, and in stainless steel metalwork, are available on request for more demanding environments. At 45 Shore A, this mount is particularly well matched to air-conditioning units, sensitive instruments, and light industrial machinery and equipment where low-frequency vibration isolation is the principal design requirement. It is equally at home on generator sets and exhaust mountings in lighter-duty configurations where isolating structure-borne noise and improving operator comfort are the primary objectives. The mount contributes to extended machinery lifespan and protects surrounding structures by decoupling vibration paths at source.

A. The 4040FF08-45 is rated to a maximum load of 31.0 kg with a deflection of 3.6 mm at that load. These figures reflect the high compliance of the 45 Shore A rubber grade, which prioritises vibration isolation over load-carrying capacity.
A. Shore A hardness measures rubber firmness. At 45 Shore A, this is the softest grade in the 40×40 mm M8 range, providing greater deflection and superior vibration isolation at lower loads. It is the appropriate choice for lighter or sensitive equipment — such as instruments, air-conditioning units, or light machinery — where isolating low-frequency vibration matters more than limiting movement under load.
A. The 4040FF08-45 uses a female-female configuration with M8 threads at both ends, allowing direct bolted installation between a bracket and equipment base without additional adaptors.
A. This bobbin mount may be loaded in shear, compression, or a combination of both, giving flexibility across different installation orientations and mounting geometries.
A. Applications include air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and light industrial machinery and equipment. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. Yes. Within the same 40×40 mm M8 body, firmer grades are available as 4040FF08-60 (60 Shore A) and 4040FF08-70 (70 Shore A) for higher loads or where less deflection is required. Larger body and thread variants include 4040FF10-45, 100100FF16, 10040FF16, 10045FF16, 10050FF16, 10055FF16, and 10060FF16. Custom sizes, oil-resistant and high-temperature rubbers, and stainless steel metalwork are also available on request.
