Product Number: 2520FF06-70

Where compact installations demand firm hold rather than soft give, the female-female bobbin mount 2520FF06-70 delivers. Measuring 25 x 20 mm with M6 female threads at both ends, this 70 Shore A rubber-to-metal bonded mount is rated to a maximum load of 41.0 kg with a controlled deflection of just 1.6 mm, the stiffest, highest-load configuration available in the 25 x 20 mm female-female bobbin range, suited to applications where movement must be minimised and the mounted item held securely under sustained or impact loading. The 70 Shore A hardness grade places this mount firmly at the firm end of the durometer scale. Harder rubber resists deformation under load, making it the appropriate choice when equipment must be constrained rather than isolated, where shock and impact forces need to be absorbed without significant displacement, and where the structural integrity of the mounting arrangement under peak loading takes priority over maximum vibration attenuation. Typical applications for this grade include exhaust mountings, generator sets, diesel engine mounts, and industrial machinery installations where heavier components or dynamic shock loads are present. The mount may be loaded in shear, compression, or a combination of both, offering installation flexibility. As with all bobbins in this family, the rubber-to-metal bonded construction serves to improve machinery lifespan, protect surrounding structures, and reduce transmitted vibration to the wider assembly.

A. The mount has an outer diameter and height of 25 x 20 mm, M6 female threads at both ends, a maximum load rating of 41.0 kg, and a deflection of 1.6 mm. The rubber element is 70 Shore A hardness.
A. 70 Shore A is a firm hardness grade. Harder grades carry higher loads with less movement, making this mount suitable for applications where the mounted item must be held firmly and displacement kept to a minimum under load or impact.
A. This mount is appropriate for exhaust mountings, generator sets, diesel engines, and industrial machinery and equipment installations — particularly where heavier loads, shock forces, or dynamic impacts must be managed within a compact footprint.
A. Yes. The bobbin mount may be loaded in shear, compression, or a combination of both, providing flexibility to suit different installation orientations.
A. Yes. The same geometry is available in 45 Shore A (SKU 2520FF06-45) for maximum deflection and isolation at lower loads, and 60 Shore A (SKU 2520FF06-60) for a mid-range balance of load capacity and vibration attenuation.
A. Yes. Oil-resistant and high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. We accept all major credit and debit cards, along with PayPal.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
