Q 1. What are the key dimensions and load figures for the 4030MFB25-60?

A. The buffer measures 40 mm diameter by 30 mm height, with an M10 x 25 mm male stud. Maximum load is 174.5 kg and deflection is 7.5 mm.

Q 2. What hardness grade is this buffer and what does that mean in practice?

A. This buffer is 60 Shore A, a medium hardness grade. It provides a balance between vibration isolation and load-bearing support, making it well-suited to mainstream general-machinery mounting at moderate loads where neither maximum compliance nor maximum rigidity is required.

Q 3. What types of loading can this buffer handle?

A. The rubber-to-metal bonded construction allows the mount to be loaded in shear, compression, or a combination of both, accommodating the varied loading conditions found across industrial, agricultural, and commercial vehicle applications.

Q 4. What applications is this male flat buffer designed for?

A. It is designed for use in industrial machinery, agricultural equipment, construction equipment, commercial vehicles, and power generation installations, serving industries including construction and off-highway, agriculture, marine, and automotive sectors.

Q 5. How does this 60 Shore A grade compare to the other grades in the 40x30 mm range?

A. The 45 Shore A version (4030MFB25-45) offers greater deflection and better isolation at lower loads, while the 70 Shore A version (4030MFB25-70) carries higher loads with less movement. The 60 Shore A grade sits in the mid-range, balancing both characteristics.

Q 6. Are custom specifications available for this buffer?

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