Where vibration isolation takes priority over load restraint, the 30x15mm Female Flat Buffer in 45 Shore A rubber offers the greatest deflection in its size class, 3.75mm under a maximum load of 90.0kg. Making it the most compliant option within the 30x15mm M8 flat buffer range. The M8 female thread provides a clean, direct fixing point, and the rubber-to-metal bonded construction ensures the elastomeric element remains securely integrated under repeated cyclical loading. At 45 Shore A, this grade is specifically suited to lighter, compact, or sensitive installations where the priority is absorbing low-frequency vibration and cushioning impact from external moving components rather than limiting deflection. Softer grades deliver greater movement under load, which translates to superior energy dissipation and improved operator comfort in equipment where vibration transmission to the surrounding structure must be minimised. Applications well matched to this grade include sensitive agricultural equipment, light-duty industrial machinery, commercial vehicle ancillaries, and precision installations within construction equipment where isolation efficiency is paramount. The flat buffer geometry allows the mount to be loaded in compression or shear, or a combination of both, providing design flexibility across a range of machinery configurations. Rubber hardness, as the source confirms, governs the performance balance: at 45 Shore A, this unit sits at the lower-load, higher-isolation end of the spectrum. For industries such as marine, power generation, and railway and mass transit, where sensitive sub-assemblies demand effective low-frequency damping with minimal rigidity, this grade provides the appropriate compliance.

A. This female flat buffer has a maximum load rating of 90.0kg and a deflection of 3.75mm at that load. The 45 Shore A rubber grade provides the highest compliance in the 30x15mm M8 range, delivering greater movement under load for superior vibration isolation.
A. Softer grades such as 45 Shore A give greater deflection and better isolation performance at lower loads. This grade is most appropriate for lighter, compact, or sensitive installations where vibration absorption and energy dissipation are the primary requirements rather than load restraint or minimal movement.
A. The buffer has an M8 female thread. The overall dimensions are 30mm diameter by 15mm height (D x H: 30 x 15mm).
A. Female flat buffers of this type are used across construction equipment, agricultural equipment, industrial machinery, commercial vehicles, marine applications, power generation equipment, and railway and mass transit systems. The 45 Shore A grade is particularly well matched to sensitive or light-duty installations within these sectors.
A. The buffer works by absorbing and dissipating energy from impact shocks and vibration transmitted by external moving components or direct contact surfaces. Rubber-to-metal bonded construction means the elastomeric element is permanently bonded to its metal insert, ensuring the rubber remains securely integrated under repeated cyclical loading.
A. Yes. The 30x15mm M8 range is also available in 60 Shore A (3015FFB08-60) and 70 Shore A (3015FFB08-70). Additional Female Flat Buffer variants in alternative sizes include 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16, and 10060FFB16. Custom sizes, stainless steel metalwork, and specialist rubber compounds are available on request.
