Product Number: 4040MM25-70
Variations
Carrying a maximum load of 74.0 kg with a controlled deflection of just 3.6 mm, the 4040MM25-70 is a 40 x 40 mm male-male bobbin mount threaded M10 x 25 mm and rated at 70 Shore A, the firmest grade in this geometry's range. Where loads are substantial and movement must be kept to a minimum, the 70 Shore compound resists displacement under both sustained weight and intermittent shock or impact, making it the grade of choice when a mounting must hold its position rather than flex freely. Rubber-to-metal bonded construction allows the mount to absorb energy in shear, compression or a combination of both, protecting surrounding structures and extending the working life of connected machinery. The male-male thread configuration provides a through-fixing arrangement that suits installations where both sides of the mount require a positive fastening point. Industries where high-load firmness is essential, including power generation, construction and off-highway plant, agricultural machinery, and marine installations. Represent the natural territory for this grade. Diesel engine mounts, heavy generator sets, and industrial machinery subject to repeated shock loading are among the demanding applications this mount is built to handle. The 70 Shore rating ensures that even at or near the 74.0 kg maximum, the 3.6 mm deflection ceiling keeps the mounted assembly stable, an attribute critical in applications where misalignment or excessive movement would affect performance or safety. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request.

A. This mount is rated to a maximum load of 74.0 kg with a deflection of 3.6 mm. The 70 Shore A rubber compound provides the least movement of the grades available in this geometry, making it suited to heavier loads and applications where positional stability is a priority.
A. Shore A is the standard scale for rubber hardness. At 70 Shore A, this is the firmest grade available in the 40 x 40 mm male-male bobbin range. Firmer rubber carries higher loads with less deflection, which is beneficial when the mount must resist shock or impact and hold the mounted assembly in a consistent position.
A. The mount uses an M10 x 25 mm male thread on both ends, providing a positive fastening point on either side of the mount for through-fixing applications.
A. The mount may be loaded in shear, compression or a combination of both, giving flexibility in how it is installed within a machine or structure.
A. Typical applications include diesel engine mounts, heavy generator sets, industrial machinery subject to shock loading, and equipment in power generation, construction and off-highway, agricultural, and marine environments where a firm, high-load mount is required.
A. Yes. The same 40 x 40 mm M10 x 25 mm geometry is available in 45 Shore A (4040MM25-45) and 60 Shore A (4040MM25-60) for applications requiring greater deflection and softer isolation. Other sizes in the family include 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44 and 10055MM44.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
