Product Number: 4035MM23-70
Variations
Rated at a maximum load of 78.0 kg with a controlled deflection of just 3.1 mm, the 4035MM23-70 is a 40 x 35 mm male-male bobbin mount with M8 x 23 mm studs and a 70 Shore A rubber element, engineered for applications where firm restraint, shock absorption and minimal movement under load are the governing requirements. At 70 Shore A, this is the firmest grade in the 40 x 35 mm male-male bobbin family, and that hardness is what distinguishes its role: it holds heavier machinery securely, resists displacement under impact, and suits installations where structural rigidity matters as much as vibration attenuation. The rubber-to-metal bonded construction allows the mount to operate in shear, compression, or a combination of both, giving engineers flexibility in orientation without sacrificing load integrity. The rubber element resists the mechanical stresses associated with diesel engines, generator sets and heavy industrial machinery, where load cycling and intermittent shock are routine rather than exceptional. This mount improves machinery lifespan, protects surrounding structures and contributes to operator comfort by attenuating transmitted vibration at source. The M8 x 23 mm male stud configuration provides direct, bolt-through installation into standard threaded housings, making this mount a straightforward fitment for general machinery, power generation plant, construction and off-highway equipment, agricultural machinery, marine applications and railway or mass transit systems. Custom options, including oil-resistant and high-temperature rubbers, as well as stainless steel hardware. Are available on request for demanding environments.

A. This mount is rated to a maximum load of 78.0 kg with a deflection of 3.1 mm, making it suited to heavier-load applications where minimal movement under load is required.
A. Shore A hardness indicates rubber stiffness. At 70 Shore A — the firmest grade in this 40 x 35 mm range — the mount carries higher loads with less movement, making it the correct choice for heavier machinery, shock and impact applications, and installations requiring firm positional restraint rather than maximum vibration isolation.
A. The mount has an outer diameter of 40 mm and a height of 35 mm, with M8 x 23 mm male studs at both ends.
A. The rubber-to-metal bonded construction allows this mount to be loaded in shear, compression, or a combination of both, giving installation flexibility depending on the application.
A. Applications include diesel engines, generator sets, industrial machinery and equipment, construction and off-highway vehicles, agricultural machinery, marine systems, and railway and mass transit applications.
A. Yes. The same geometry is available in 45 Shore A (4035MM23-45) for greater deflection and improved isolation at lower loads, and 60 Shore A (4035MM23-60) as a mid-range option. Related bobbin sizes are also available: 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44 and 10055MM44.
A. Yes. Oil-resistant and high-temperature rubber compounds, as well as stainless steel hardware, are available on request for specialist or demanding environments.
A. We accept all major credit and debit cards, along with PayPal.
