Product Number: 4040MFB23-70
Variations
Where machinery must be held firmly against heavier loads and repeated impact, the 40x40mm Male Flat Buffer in 70 Shore A (4040MFB23-70) delivers a maximum load capacity of 199.0 kg with a controlled deflection of just 10.0 mm, the firmest grade in this geometry, built for applications where minimal movement under load is essential. The M8 x 23 mm male stud allows straightforward bolted installation directly to frames, housings, or structural members, with rubber-to-metal bonded construction ensuring the mount remains integral under sustained compression or shear loading. At 70 Shore A, this buffer is best suited to roles where shock and impact forces must be absorbed without permitting significant displacement: restraining components subject to sudden loading, cushioning actuator end-stops, and protecting surrounding structure in high-cycle impact environments. The rubber compound works by absorbing and dissipating kinetic energy, reducing peak impact force transmitted to the machine frame and improving the service life of adjacent components. The 40 x 40 mm flange geometry distributes load across a broad contact face, making it effective as a direct-contact elastic element between moving and static surfaces. Typical deployment sectors include construction equipment, agricultural machinery, industrial plant, commercial vehicles, and power generation equipment. Custom options, including oil-resistant or high-temperature rubber compounds and stainless steel hardware. Are available on request for demanding environments. This buffer is available in softer grades for greater deflection and better isolation at lower loads: 45 Shore A (4040MFB23-45) and 60 Shore A (4040MFB23-60).

A. The 4040MFB23-70 has a maximum load capacity of 199.0 kg and a deflection of 10.0 mm. As the firmest grade in this size, it carries the highest load with the least movement.
A. The buffer body is 40 mm diameter by 40 mm height (D x H: 40 x 40). The male stud is M8 with a length of 23 mm (d x L: M8 x 23).
A. The 70 Shore A grade is designed for heavier loads, shock and impact absorption, and situations where the mounted component must be held firmly with minimal displacement. Typical applications include construction equipment, agricultural machinery, industrial plant, commercial vehicles, and power generation equipment.
A. Harder grades carry higher loads with less movement; softer grades give greater deflection and better vibration isolation at lower loads. The 70 Shore A (4040MFB23-70) offers the highest load capacity in this geometry, while the 45 Shore A (4040MFB23-45) and 60 Shore A (4040MFB23-60) are better suited to lighter-duty isolation duties.
A. Additional sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44. All variants are listed on the PartsForMachines platform.
A. Yes — stainless steel hardware and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. The M8 x 23 mm male stud threads directly into a tapped hole or nut on the mounting surface, making installation straightforward. The rubber-to-metal bonded construction keeps the unit integral during service.
