Where vibration isolation takes priority over load restraint, the 40x30mm Male-Male Bobbin Mount in 45 Shore A rubber delivers the most movement under load within this geometry, a 2.6 mm deflection at a maximum capacity of 33.0 kg. Carrying male threaded studs of M8 x 23 mm at both ends, this compact mount is the natural choice for lighter or sensitive installations where absorbing low-frequency vibration matters most. The 45 Shore A rubber compound is the softest grade available in this geometry, and that softness is its primary advantage: softer grades yield greater deflection and superior isolation performance under lower loads, protecting delicate instruments, compact machinery, and vibration-sensitive equipment from transmitted shock and vibration. The rubber-to-metal bonded construction ensures the elastomer element remains mechanically secure throughout service life, while the dual male stud configuration simplifies fitment in line-of-axis installations. This mount is suited to applications where equipment is light and the priority is decoupling structure-borne vibration rather than restraining mass under high dynamic load. Typical uses drawn from the product family include instruments, air-conditioning units, and smaller industrial machinery and equipment across sectors including power generation, marine, agriculture, automotive, and construction and off-highway. The mount may be loaded in shear, compression, or a combination of both, giving installation flexibility to suit varying mounting geometries. This 45 Shore A grade sits at the softer end of the 40x30mm Male-Male range. Firmer grades in the same geometry are available as 4030MM23-60 (60 Shore A) and 4030MM23-70 (70 Shore A).

A. The mount measures 40 mm diameter by 30 mm height. The threaded studs are M8 with a 23 mm stud length at each end. Maximum load capacity is 33.0 kg, with a deflection of 2.6 mm under that load.
A. The 45 Shore A compound is the softest grade in this geometry. Softer rubber gives greater deflection and better vibration isolation at lower loads, making it the right choice where the priority is decoupling vibration from sensitive or lightweight equipment rather than restraining heavier mass.
A. This mount may be loaded in shear, compression, or a combination of both, offering flexibility to suit different mounting arrangements.
A. The product family is designed for applications including instruments, air-conditioning units, exhaust mountings, diesel engines, generator sets, and industrial machinery and equipment. Industries served include power generation, marine, agriculture, automotive, construction and off-highway, railway and mass transit, and military and defence.
A. Yes. The same geometry is available in 60 Shore A (4030MM23-60) and 70 Shore A (4030MM23-70). Firmer grades carry higher loads with less deflection, while this 45 Shore A grade offers maximum deflection and isolation for lighter applications.
A. Yes. The male-male bobbin range includes a wide selection of sizes and load capacities, including 0808MM06, 100100MM44, 10030MM44, 10040MM44, 10050MM44, and 10055MM44, among others.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
