Q 1. What are the load and deflection ratings for the 5040MM25-60 bobbin mount?

A. The 5040MM25-60 is rated to a maximum load of 91.0 kg and provides a deflection of 3.5 mm, making it suited to moderate-load general machinery mounting duties.

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

A. Both studs are M10 with a length of 25 mm, and the overall body dimensions are 50 mm diameter by 40 mm height.

Q 3. What does the 60 Shore A hardness grade mean for this mount?

A. At 60 Shore A, this is the medium grade in the 50×40 mm bobbin range. It balances vibration isolation against load-carrying support, offering controlled deflection suitable for the broad middle ground of general machinery mounting — harder than the 45 Shore A (which gives more compliance at lower loads) and softer than the 70 Shore A (which carries higher loads with less movement).

Q 4. In which loading 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 oriented within the mounting arrangement.

Q 5. What types of machinery and equipment is this bobbin mount suitable for?

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

Q 6. Are alternative Shore hardness grades available in this 50×40 mm M10 bobbin size?

A. Yes. The same 50×40 mm M10 × 25 geometry is available in a 45 Shore A grade (SKU 5040MM25-45) for greater deflection and isolation at lighter loads, and a 70 Shore A grade (SKU 5040MM25-70) for higher-load, lower-deflection applications.

Q 7. Are special material options available for this mount?

A. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for applications requiring enhanced corrosion resistance or elevated operating temperatures.
