Q 1. What load and deflection figures apply to the 4025MM25-45?

A. This mount has a maximum load rating of 38.0 kg and a deflection of 2.1 mm under load, reflecting the higher compliance of the 45 Shore A soft rubber grade.

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

A. A 45 Shore A rating places this mount at the softer end of the hardness range. Softer grades yield greater deflection and better vibration isolation at lower loads, making this grade most effective where protecting sensitive equipment or reducing transmitted vibration takes priority over high load-bearing capacity or firm restraint.

Q 3. What thread size and configuration does this mount use?

A. The mount uses M10 x 25 mm male-male threaded studs on both ends, allowing direct in-line installation between a machine and its mounting surface.

Q 4. In what axes can this bobbin mount be loaded?

A. The rubber-to-metal bonded construction allows the mount to be loaded in shear, compression, or a combination of both, providing installation flexibility across different mounting orientations.

Q 5. What types of equipment is this bobbin mount suited to?

A. Applications in the product family include air-conditioning units, exhaust mountings, diesel engines, generator sets, instruments, and general industrial machinery and equipment. The 45 Shore A soft grade is particularly suited to lighter or sensitive installations where low-frequency vibration isolation is the primary requirement.

Q 6. Are other Shore hardness grades available in the same 40x25mm M10 size?

A. Yes. The same geometry is available in 60 Shore A (4025MM25-60) and 70 Shore A (4025MM25-70) for applications requiring higher load capacity or reduced deflection.

Q 7. Are custom sizes or special rubber compounds available?

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