Product Number: 3040MFB20-45
Sensitive and compact installations demand a buffer that prioritises isolation over restraint, and the 30x40mm Male Flat Buffer (SKU: 3040MFB20-45) is built precisely for that role. With a 45 Shore A rubber element bonded to the metal stud, this soft-grade mount accepts up to 53.5 kg maximum load and yields 10.0 mm of deflection, characteristics that translate directly into effective absorption of lower-frequency vibration and impact energy in lighter machinery and equipment. The Male Flat Buffer format offers low-cost shock and vibration absorption in a straightforward design: the rubber element works by absorbing and dissipating energy, reducing impact force from a secondary object or acting as an elastic element in direct contact with a surface. The M8 x 20 mm male stud makes installation clean and repeatable across standard threaded fixings, while the rubber-to-metal bonded construction ensures the assembly holds its geometry under cyclic loading. At 45 Shore A, this is the softer end of the flat buffer range, making it the grade of choice where isolating lighter loads from vibration sources matters more than high-load restraint. Typical applications drawn from the family include agricultural equipment, light industrial machinery, construction equipment, elevators, and commercial vehicles, anywhere a sensitive or compact installation requires maximum vibration isolation with controlled movement under load. The softer compound also benefits operator comfort and helps protect surrounding structures from transmitted shock. This SKU is the 45 Shore A variant of the 30x40mm Male Flat Buffer.

A. The 3040MFB20-45 Male Flat Buffer has a maximum load rating of 53.5 kg and a deflection of 10.0 mm, reflecting the compliant, high-movement characteristics of its 45 Shore A rubber grade.
A. The mount uses an M8 male stud with a 20 mm thread length, suitable for standard M8 threaded fixings on equipment panels, frames, and brackets.
A. Softer grades such as 45 Shore A deliver greater deflection and better vibration isolation at lower loads, making them the correct choice for lighter or sensitive equipment and for applications where absorbing lower-frequency vibration is the primary requirement rather than high-load restraint.
A. Male Flat Buffers in the 45 Shore A grade are suited to agricultural equipment, light industrial machinery, construction equipment, elevators, and commercial vehicles — particularly where compact or sensitive installations require maximum vibration isolation and improved operator comfort.
A. The buffer works by absorbing and dissipating energy through its rubber element, which can be loaded in shear, compression, or a combination of both. The rubber-to-metal bonded construction maintains geometry under cyclic loading and reduces impact force transmitted to surrounding structures.
A. Yes. The 30x40mm Male Flat Buffer is also available in 60 Shore A (3040MFB20-60) and 70 Shore A (3040MFB20-70). The wider Male Flat Buffer range includes additional sizes: 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
