Where maximum vibration isolation matters more than restraint, the 75 x 55 mm Female Flat Buffer with M12 thread and 45 Shore A rubber delivers the greatest deflection in this geometry's Shore range. At a maximum load of 435 kg and a deflection of 13.75 mm, the soft-grade compound yields more freely under load than firmer grades, making it the appropriate choice when absorbing low-frequency vibration from lighter or sensitive equipment is the priority. Rubber-to-metal bonded construction ensures the elastomer remains securely captured between the metal faces throughout the working cycle. The 45 Shore A hardness grade is specifically suited to applications where the mount must isolate rather than restrain, situations where energy absorption and compliance take precedence. Because softer rubber moves more under the same load, it attenuates vibration more effectively at lower frequencies and reduces the transmitted force passed on to surrounding structures, improving both machinery lifespan and operator comfort. Mounts of this type can be loaded in compression, shear, or a combination of both, broadening the range of installation configurations available to the engineer. Female Flat Buffers of this construction are used across construction equipment, agricultural machinery, industrial plant, commercial vehicles, elevators, and power generation equipment. The 75 x 55 mm body with M12 female thread suits mainstream general-machinery mounting positions where a moderate-load, high-compliance mount is required and the M12 fixing interface is specified. Industries served by this buffer family include construction and off-highway, agriculture, marine, railway and mass transit, and automotive.

A. The buffer measures 75 mm diameter by 55 mm height with an M12 female thread. It has a maximum load rating of 435 kg and a deflection of 13.75 mm.
A. The 45 Shore A grade is the softest option in this geometry. Softer rubber produces greater deflection under load, which delivers better vibration isolation at lower frequencies and is the preferred choice where isolation of lighter or sensitive equipment takes priority over high load-bearing or restraint.
A. The buffer can be loaded in compression, shear, or a combination of both, allowing flexibility across different installation configurations and machinery types.
A. This buffer is used across construction and off-highway equipment, agricultural machinery, industrial plant, commercial vehicles, elevators, and power generation equipment. It is also applicable in marine, railway and mass transit, and automotive sectors.
A. Yes. The same 75 x 55 mm M12 footprint is available in 60 Shore A (7555FFB12-60) and 70 Shore A (7555FFB12-70) for applications requiring a stiffer mount with higher load resistance and less deflection.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, in addition to custom sizes.
A. We accept returns within 30 days of purchase for items that are unused, undamaged, and in their original packaging. Returns are available only for UK-delivered orders and must include proof of purchase. Before returning an item, please contact us at [email protected] to obtain a Return Merchandise Number (RMN).
A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
