Product Number: 7540MFB37-45
Variations
Engineered for maximum vibration isolation rather than restraint, the 7540MFB37-45 is a 75 x 40 mm male flat buffer with an M12 x 37 mm threaded stud, rated to a maximum load of 533 kg and a deflection of 10 mm at 45 Shore A hardness. At the softer end of the male flat buffer range, this grade prioritises energy absorption and compliance, allowing the rubber element to move more freely under load, a characteristic that makes it well suited to applications where isolating low-frequency vibration or cushioning sensitive equipment is the primary objective. The rubber-to-metal bonded construction provides dependable performance in direct contact applications, where the buffer acts as an elastic element between machinery and an adjoining surface, or absorbs impact energy from an external moving component. Softer 45 Shore A rubber delivers greater deflection than harder grades across the same 75 x 40 mm geometry, making it the preferred choice when operator comfort, protection of precision components, or the integrity of surrounding structures takes priority over maximum load restraint. Mounts may be loaded in compression, shear, or a combination of both. The male flat buffer format is a low-cost, straightforward solution for shock and vibration control, and this size is applicable across construction equipment, agricultural machinery, industrial plant, commercial vehicles, and elevator installations. Industries including power generation, marine, railway and mass transit, and military and defence also make use of this buffer geometry where the 45 Shore A compliance characteristic meets the isolation requirement.

A. The buffer measures 75 mm diameter by 40 mm height. The threaded stud is M12 with a 37 mm stud length.
A. The 7540MFB37-45 has a maximum load rating of 533 kg and a deflection of 10 mm.
A. At 45 Shore A, the rubber is softer and deflects more under load than harder grades of the same 75 x 40 mm geometry. This gives greater vibration isolation and energy absorption, which is beneficial when protecting sensitive equipment, improving operator comfort, or isolating lower-frequency vibration where compliance matters more than stiffness.
A. Typical applications include construction equipment, agricultural machinery, industrial plant, elevators, and commercial vehicles. It is also used across power generation, marine, railway and mass transit, automotive, and military and defence industries, wherever shock cushioning or vibration isolation is required.
A. The buffer absorbs and dissipates energy through its rubber element, either cushioning impact from an external moving component or acting as an elastic element in direct contact with a surface. It may be loaded in compression, shear, or a combination of both.
A. Yes — the 7540MFB37-45 uses rubber-to-metal bonded construction, which integrates the rubber element and the metal stud into a single assembly for reliable performance under repeated loading.
A. Yes. The 75 x 40 mm format is also available in 60 Shore A (7540MFB37-60) and 70 Shore A (7540MFB37-70). Other male flat buffer sizes include 100 x 100 mm (100100MFB44), 100 x 30 mm (10030MFB41), 100 x 40 mm (10040MFB44), 100 x 50 mm (10050MFB41), 100 x 55 mm (10055MFB44), and 8 x 8 mm (0808MFB06).
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, along with custom and additional sizes not shown in the standard range.
