Q 1. What load and deflection figures apply to the 4035FF08-45?

A. This mount has a maximum rated load of 27.0 kg and a deflection of 2.5 mm. These figures reflect the soft 45 Shore A rubber grade, which provides the greatest compliance and deflection within the 40 x 35 mm M8 female-female family.

Q 2. When should I choose the 45 Shore A grade rather than a harder grade?

A. The 45 Shore A grade is the correct choice when vibration isolation is the primary requirement — particularly for lighter, sensitive, or compact equipment and for lower-frequency vibration where maximum deflection and compliance are needed. Harder grades carry higher loads with less movement but attenuate vibration less effectively at lower frequencies.

Q 3. What thread configuration does this bobbin mount use?

A. The 4035FF08-45 uses a female-female M8 thread configuration, allowing direct in-line fitting between a baseplate and equipment chassis without additional adaptor hardware.

Q 4. In which load directions can this mount be used?

A. The mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is orientated within an installation.

Q 5. What types of equipment and industries is this mount suited to?

A. This soft-grade mount is applicable to air-conditioning units, instrument panels, generator sets, and light industrial machinery and equipment. Industries served include construction and off-highway, agriculture, marine, power generation, automotive, and railway and mass transit.

Q 6. Are alternative grades or custom specifications available for this bobbin mount geometry?

A. Yes. The same 40 x 35 mm M8 female-female geometry is available in 60 Shore A (4035FF08-60) and 70 Shore A (4035FF08-70) for higher-load or firmer-restraint applications. Custom sizes, stainless steel metalwork, and oil-resistant or high-temperature rubber compounds are also available on request.

Q 7. How long does delivery take?

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.

Q 8. What is your returns policy?

A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging. Returns are available only for UK-delivered orders and must include proof of purchase. Before returning an item, please contact us at [email protected] to obtain a Return Merchandise Number (RMN).
