Q 1. What is the maximum load and deflection rating for the 1515FF04-70?

A. The 1515FF04-70 has a maximum load rating of 15.8 kg and a deflection of 1.3 mm, reflecting the firm 70 Shore A rubber grade's characteristic of carrying load with minimal movement.

Q 2. What thread size and dimensions does this bobbin mount use?

A. The mount measures 15 mm in diameter by 15 mm in height (D x H: 15 x 15 mm) with an M4 female thread at both ends, providing a compact double-female fixing arrangement.

Q 3. What is the difference between the 45, 60, and 70 Shore A grades in this 15 x 15 mm M4 range?

A. The three hardness grades suit different loading and isolation priorities. The 45 Shore A grade (1515FF04-45) provides greater deflection and better vibration isolation at lower loads. The 60 Shore A grade (1515FF04-60) offers a general-purpose balance of load capacity and isolation. The 70 Shore A grade (1515FF04-70) carries the highest load with the least deflection, making it appropriate for applications requiring firm retention and shock resistance.

Q 4. In what 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 mounting orientation across a range of installation types.

Q 5. What applications is the 70 Shore A grade particularly suited to?

A. The firm 70 Shore A grade is well suited to exhaust mountings, instrument panels subject to mechanical shock, small generator sets, and automotive or off-highway components where positive restraint is needed. It also serves agricultural, marine, railway, and general industrial machinery applications requiring an M4 fixing and a firm, load-bearing mount.

Q 6. Are alternative materials available for specialist environments?

A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for applications where standard materials are not suitable.

Q 7. What if my order arrives damaged or incorrect?

A. WhatsApp us on 07754 288583 with photos of the item and packaging, and we will resolve the issue in line with our returns policy.

Q 8. When will my order be dispatched?
