Where vibration isolation takes priority over restraint, the 40x20mm male-male bobbin mount in 45 Shore A rubber, sKU 4020MM23-45. Delivers the softest deflection characteristic in this diameter family. Rated to a maximum load of 41.0 kg with a deflection of 1.6 mm, and fitted with M8x23 threaded studs on both faces, this mount is configured for lighter or compact installations where preserving instrument accuracy, protecting sensitive enclosures, or absorbing lower-frequency vibration is the primary requirement. The rubber-to-metal bonded construction couples a soft 45 Shore A rubber element between twin steel studs, allowing the mount to operate in shear, compression, or a combined loading mode. At this hardness grade the rubber yields sufficient movement under load to attenuate vibration efficiently, suited to situations where isolation quality matters more than stiffness or positional restraint. Oil-resistant and high-temperature rubber variants, together with stainless steel hardware, are available on request for demanding chemical or thermal environments. This mount addresses a wide application base including air-conditioning units, exhaust mountings, instruments, and industrial machinery and equipment across sectors such as agriculture, power generation, marine, and automotive. Its compact 40x20mm body keeps overall installation height low, making it a practical choice for panel-mounted electronics, generator auxiliaries, and similar light-duty situations where space is at a premium. The 4020MM23 geometry is also offered in 60 Shore A (4020MM23-60) and 70 Shore A (4020MM23-70) for heavier loads or where reduced deflection is needed.

A. The mount measures 40 mm diameter by 20 mm height, with M8x23 threaded studs on both faces. Maximum load rating is 41.0 kg and deflection at rated load is 1.6 mm.
A. The 45 Shore A rubber is the softest grade in this geometry. Softer rubber gives greater deflection and better vibration isolation at lower loads, making it the appropriate choice when isolation quality is the priority rather than maximum load-carrying capacity or minimal movement.
A. The mount may be loaded in shear, compression, or a combination of both, giving installation flexibility across different mounting configurations.
A. Typical applications include air-conditioning units, exhaust mountings, instruments, and industrial machinery and equipment. It is well suited to lighter or compact installations across sectors such as agriculture, power generation, marine, and automotive where lower-frequency vibration isolation is needed.
A. Yes. Oil-resistant and high-temperature rubbers, as well as stainless steel hardware, are available on request for environments involving elevated temperatures or chemical exposure.
A. The same 40x20mm M8 body is available in 60 Shore A (4020MM23-60) and 70 Shore A (4020MM23-70) for higher loads or less deflection. The wider range includes 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44, covering mounting weights from approximately 1 kg to 2,000 kg.
A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product tech specs or datasheet where available.
