Q 1. What are the load and deflection ratings of the 5040MF25-70?

A. This mount has a maximum load capacity of 130.0 kg and a deflection of 3.5 mm, reflecting its 70 Shore A firm rubber formulation, which prioritises load-carrying and movement restraint over high deflection.

Q 2. What thread sizes does the 5040MF25-70 use?

A. The mount features an M10 x 25 male stud on one end and an M10 female thread on the other, suiting direct in-line installation between a baseframe and the supported item.

Q 3. What is the overall size of this bobbin mount?

A. The outer dimensions are 50 mm diameter by 40 mm height (D x H: 50 x 40 mm).

Q 4. In which directions can this mount be loaded?

A. The rubber-to-metal bonded construction allows the mount to be used in shear, compression, or a combination of both loading directions.

Q 5. What types of equipment is the 70 Shore A grade suited to?

A. At 70 Shore A, this firm-grade mount is designed for heavier loads, shock and impact attenuation, and applications requiring firm mechanical restraint — including diesel engines, generator sets, exhaust mountings, heavy industrial machinery, and equipment in construction, agriculture, marine, and power-generation sectors.

Q 6. Are other Shore hardness grades available in the same 50 x 40 mm male-female size?

A. Yes — the same geometry is available in 45 Shore A (5040MF25-45) for greater deflection and isolation at lower loads, and 60 Shore A (5040MF25-60) for a mid-range balance between isolation and load capacity.

Q 7. Are special material options available for harsh environments?

A. Stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request for applications with elevated chemical or thermal demands.
