Q 1. What are the key dimensions and load specification for the 5025MF25-45?

A. The mount has an outer diameter of 50 mm and a height of 25 mm (D x H). The male stud is M10 x 25 mm (d1 x L) and the female insert is M10 (d2). Maximum load is 81.0 kg with a deflection of 2.0 mm.

Q 2. What does the 45 Shore A hardness grade mean for this mount in practice?

A. A 45 Shore A rubber is a soft grade. Softer grades give greater deflection under load and deliver better vibration isolation, particularly at lower frequencies. This makes the 5025MF25-45 suited to lighter or sensitive equipment where isolating transmitted vibration takes priority over stiffness or restraint.

Q 3. In which directions can the 5025MF25-45 be loaded?

A. The mount may be loaded in shear, compression, or a combination of both, giving installation flexibility in terms of orientation relative to the vibration source.

Q 4. What types of equipment is this soft-grade bobbin mount typically used with?

A. Applications include air-conditioning units, instruments and sensitive equipment, diesel engines in lighter power generation plant, and industrial machinery where lower-frequency isolation and protection of surrounding structures or operators are the primary requirements.

Q 5. Are harder Shore grades available in the same 50x25mm M10 geometry?

A. Yes. The 5025MF25-60 (60 Shore A) and 5025MF25-70 (70 Shore A) use the same dimensional envelope and thread configuration, offering progressively higher load capacity and reduced deflection for applications where greater stiffness or restraint is needed.

Q 6. Are custom material options available for this bobbin mount?

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

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