Variations
Where maximum vibration isolation takes priority over load restraint, the 25x25mm Female-Female Bobbin Mount in 45 Shore A rubber delivers the greatest deflection in this geometry's Shore range. Carrying up to 13.0 kg per mounting with a rated deflection of 2.1 mm, SKU 2525FF08-45 is engineered for lighter, compact or sensitive installations where the rubber's softness is an asset rather than a compromise, absorbing low-frequency vibration energy before it propagates into surrounding structures or instrumentation. The bobbin's rubber-to-metal bonded construction accepts loading in shear, compression, or a combination of both, making it adaptable to varied mounting orientations. The female-female M8 thread configuration at both ends allows direct bolt-through installation without intermediate hardware, keeping the mounting envelope minimal. At 45 Shore A, the softer compound yields more readily under dynamic load, which translates into superior isolation efficiency for equipment operating at lower excitation frequencies. Typical applications include instrument mounting, air-conditioning units, sensitive electronic enclosures, and lighter industrial machinery where protecting the host structure or the equipment itself from transmitted vibration is the primary requirement. The mount is equally suited to exhaust mountings and compact generator sets where isolation of structure-borne noise is valued. Industries served by this family include agriculture, marine, automotive, and power generation. For higher load capacities or increased stiffness within the same 25x25mm M8 female-female geometry, the 60 Shore A variant (2525FF08-60) and 70 Shore A variant (2525FF08-70) are available. Larger bobbin formats in this family include 100100FF16, 10040FF16, 10045FF16, 10050FF16, 10055FF16, and 10060FF16.

A. The 2525FF08-45 is rated to a maximum load of 13.0 kg per mounting, with a rated deflection of 2.1 mm. These figures reflect the 45 Shore A compound's greater compliance, which provides superior vibration isolation at lighter loads compared with harder grades in the same geometry.
A. At 45 Shore A, the rubber compound is at the softer end of the hardness range for this bobbin family. Softer grades yield more deflection under load, which means they absorb and dissipate vibration energy more effectively — particularly at lower excitation frequencies. This makes the 45 Shore A grade well matched to instruments, sensitive electronic enclosures, air-conditioning units, and other lightweight equipment where isolation performance outweighs the need for stiff restraint.
A. The mount may be loaded in shear, compression, or a combination of both. This flexibility in loading orientation allows the mount to be adapted to a range of installation configurations without requiring a dedicated geometry for each direction.
A. The 2525FF08-45 uses an M8 female thread at both ends (female-female configuration). The overall body dimensions are 25 mm diameter by 25 mm height.
A. The family source identifies applications including air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and industrial machinery. The 45 Shore A grade is particularly relevant where isolation of lighter loads or lower-frequency vibration is the primary requirement. Industries served include agriculture, marine, automotive, power generation, construction and off-highway, and railway and mass transit.
A. Yes. Within the same 25x25mm M8 female-female geometry, the 60 Shore A (2525FF08-60) and 70 Shore A (2525FF08-70) variants offer progressively higher load capacity and stiffness. Larger format bobbins in the wider family include 100100FF16, 10040FF16, 10045FF16, 10050FF16, 10055FF16, and 10060FF16. Custom sizes, stainless steel components, and specialist rubber compounds are also available on request.
A. Yes. Stainless steel metal components, oil-resistant rubber, high-temperature rubber compounds, and additional or custom sizes are available on request.
