Where sensitive equipment demands maximum isolation rather than restraint, the 4030MF25-45 male-female bobbin mount offers a 45 Shore A rubber compound that prioritises deflection and compliance over load stiffness. At 40mm diameter by 30mm height, with an M10 x 25mm male stud and M10 female thread, this mount is sized for lighter or compact installations where absorbing low-frequency vibration and protecting delicate equipment takes precedence. With a maximum load rating of 34.0 kg and a deflection figure of 2.6 mm, it is positioned at the lower end of the load range, making it well suited to applications where movement under load is an advantage rather than a limitation. The rubber-to-metal bonded construction allows the mount to operate in shear, compression, or a combination of both. The softer 45 Shore A compound delivers greater deflection relative to the harder grades in this geometry, directly translating to improved vibration isolation efficiency at lighter loads. This characteristic makes it particularly appropriate for instruments, air-conditioning units, and similar equipment where transmitted vibration or shock must be minimised to protect components or maintain performance. The bonding process between rubber element and metal hardware ensures structural integrity across all loading axes throughout service life. Designed as a low-cost anti-vibration solution across diverse industrial sectors, the male-female configuration suits installations where one end must thread directly into a tapped housing or bracket while the opposite stud provides the mounting point.

A. The mount measures 40mm diameter by 30mm height (D x H). The male stud is M10 x 25mm and the female thread is M10. Maximum load rating is 34.0 kg with a deflection of 2.6 mm at that load.
A. The 4030MF25-45 uses a male-female configuration: one end has an M10 x 25mm male stud for attachment to a bracket or baseplate, and the opposite end has an M10 female threaded insert to receive a bolt from the equipment side.
A. A softer 45 Shore A compound provides greater deflection under load and superior vibration isolation compared with harder grades. This makes it the correct choice for lighter or sensitive equipment and installations where minimising transmitted vibration matters more than limiting movement.
A. This mount may be loaded in shear, compression, or a combination of both, giving flexibility in how it is oriented within an installation.
A. The mount family is designed for air-conditioning units, instruments, diesel engines, generator sets, exhaust mountings, and general industrial machinery and equipment. Industries served include agriculture, power generation, marine, automotive, construction and off-highway, and railway and mass transit.
A. Yes. Stainless steel hardware, oil-resistant rubber, and high-temperature rubber compounds are available on request, as are additional and custom sizes outside the standard range.
A. Two firmer grades are available in the same 40 x 30 mm male-female format: 4030MF25-60 (60 Shore A) and 4030MF25-70 (70 Shore A). These carry higher loads with less deflection and suit applications requiring greater restraint.
