Q 1. What is the maximum load rating and deflection for the 5040MM25-70 bobbin mount?

A. This mount has a maximum load capacity of 126.0 kg and a deflection of 3.5 mm, making it the firmest 50x40mm M10 grade and suitable for heavier-duty applications where movement must be kept to a minimum.

Q 2. What thread size and stud length does the 5040MM25-70 use?

A. The mount uses M10 threaded studs with a 25 mm length on each end, in a male-male configuration for direct in-line fixing between two threaded structures.

Q 3. What does 70 Shore A hardness mean in practice for this bobbin mount?

A. A 70 Shore A rubber grade is the firmest in this geometry range. It carries higher loads with less deflection than softer grades, making it appropriate for heavy machinery, diesel engines, generator sets, and applications subject to shock or sustained load where positional restraint is important.

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

A. The mount may be loaded in shear, compression, or a combination of both, giving installation flexibility in orientation without compromising performance.

Q 5. Which industries and applications is this mount suited to?

A. Documented applications include diesel engines, generator sets, industrial machinery and equipment, air-conditioning units, and exhaust mountings. Industries served include power generation, construction and off-highway, agriculture, marine, railway and mass transit, automotive, and military and defence.

Q 6. Is this mount available in other Shore hardness grades or sizes?

A. Yes. The same 50x40mm M10x25 geometry is available in 45 Shore A (5040MM25-45) and 60 Shore A (5040MM25-60) for applications requiring greater deflection and lower-load isolation. Related male-male bobbin variants include 5045MM25-70, 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44.

Q 7. Are custom materials or non-standard sizes available for this bobbin mount family?

A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
