Where vibration isolation takes priority over load restraint, the 40x40mm Male-Male Bobbin Mount at 45 Shore A hardness delivers exactly that balance, rated to 29.0 kg maximum load with 3.6 mm deflection, this softer-grade mount is engineered for lighter, sensitive installations where absorbing movement and protecting delicate equipment matters most. Thread configuration is M10 x 25 mm, with male fixings at both ends for straightforward inline mounting between a machine and its base or bracket. The 45 Shore A rubber compound sits at the softer end of the hardness range, which means greater deflection per unit of load and superior isolation of lower-frequency vibration. This makes it well suited to applications where excessive stiffness would transmit rather than attenuate unwanted movement. The rubber-to-metal bonded construction ensures a secure, durable connection between the elastomer and the steel inserts under operational conditions. Mounts of this type may be loaded in shear, compression, or a combination of both, giving installation engineers flexibility in orientation without compromising performance. Typical applications for this softer 45 Shore A grade include instruments and sensitive monitoring equipment, air-conditioning units, and lighter industrial machinery where protection of surrounding structures and improvement of operator comfort are the primary objectives. The male-male bobbin geometry, also referred to as Type A or Type 1 in the family. Suits installations requiring a compact, low-profile anti-vibration solution across construction and off-highway, agricultural, power generation, and marine environments.

A. The mount body is 40 mm diameter by 40 mm height (D x H), with M10 x 25 mm male threads. Maximum load rating is 29.0 kg and deflection at rated load is 3.6 mm.
A. At 45 Shore A, this is the softer grade in the 40x40mm male-male range. Softer rubber produces greater deflection under load and provides better vibration isolation, particularly at lower frequencies. It is best suited to lighter or sensitive equipment where isolation performance is the priority rather than high load-carrying capacity or minimal movement.
A. This bobbin mount may be loaded in shear, compression, or a combination of both, giving installation engineers flexibility in how the unit is oriented without compromising its anti-vibration performance.
A. Applications include instruments and sensitive monitoring equipment, air-conditioning units, and lighter industrial machinery. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. Yes. This mount uses rubber-to-metal bonded construction, which bonds the elastomer securely to the steel inserts, ensuring a durable and reliable connection under operational loading conditions.
A. Yes. The same 40x40mm male-male geometry is available in 60 Shore A (4040MM25-60) and 70 Shore A (4040MM25-70) for higher load or reduced deflection requirements. Additional male-male bobbin sizes include 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44. Custom sizes, stainless steel metals, and oil-resistant or high-temperature rubber compounds are also available on request.
A. Yes. Stainless steel metal components and oil-resistant or high-temperature rubber compounds are available on request, alongside additional and custom sizes.
