Q 1. What is the maximum load and deflection for the 4035FF10-70?

A. This mount has a maximum load rating of 79.0 kg and a deflection of 2.5 mm, making it the firmest grade in the 40×35 mm M10 female-female bobbin range.

Q 2. What does 70 Shore A mean in practice for this bobbin mount?

A. A 70 Shore A hardness rating indicates a firm rubber compound. Compared with softer grades of the same geometry, the 70 Shore A grade carries higher loads with less movement — prioritising restraint and rigidity over maximum vibration isolation.

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

A. The 4035FF10-70 has an M10 female thread at both ends, allowing it to be bolted directly between two male-threaded fixing points without additional adaptors.

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

A. This bobbin mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is orientated within the mounting arrangement.

Q 5. What are the typical applications for this firm-grade bobbin mount?

A. The 70 Shore A grade is suited to diesel engines, generator sets, industrial machinery and equipment, and exhaust mountings — installations where heavier loads, shock, or impact forces require a mount that holds equipment firmly with minimal deflection.

Q 6. Are alternative hardness grades available in the same 40×35 mm M10 geometry?

A. Yes. Softer grades offering greater deflection and isolation at lower loads are available as 4035FF10-45 and 4035FF10-60. Larger M16 female-female mounts are listed as 100100FF16, 10040FF16, 10045FF16, 10050FF16, 10055FF16, and 10060FF16.

Q 7. Are special materials available for harsh or high-temperature environments?

A. Yes. Stainless steel hardware and oil-resistant or high-temperature rubber compounds can be supplied on request for applications where standard materials are not suitable.

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).

Q 10. When will my order be dispatched?
