Where compact dimensions meet a firm duty requirement, the 20x30mm Female Flat Buffer in 70 Shore A rubber delivers the highest load resistance within the 20x30 M6 flat buffer range. Rated to a maximum load of 44.5 kg with a controlled deflection of just 7.5 mm, SKU 2030FFB06-70 is specified for installations where shock and impact forces must be arrested with minimal movement, holding components firmly in place under heavier cyclic loading than softer grades of the same geometry permit. Rubber-to-metal bonded construction gives the buffer its characteristic ability to absorb and dissipate impact energy without fastener loosening or progressive creep. The female M6 thread accepts a through-bolt or stud mount, making installation straightforward in confined assemblies. The 70 Shore A compound carries load predominantly in compression, resisting deflection where positional stability matters more than compliant isolation. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request. Applications suited to this firm 70 Shore A grade include construction and off-highway equipment subject to intermittent impact loading, agricultural machinery mounts where heavier components must be restrained, commercial vehicles, power generation plant, marine and railway structures, and industrial machinery requiring a positive end-stop or shock buffer. The 70 Shore A grade is the appropriate choice when load capacity and low deflection are the governing design criteria rather than maximum vibration isolation.

A. This buffer has a maximum load rating of 44.5 kg and a deflection of 7.5 mm, making it the firmest option in the 20x30mm M6 flat buffer range.
A. The buffer uses a female M6 thread, designed to accept a through-bolt or stud for straightforward installation in confined assemblies.
A. Shore A hardness describes the rubber compound's resistance to indentation. At 70 Shore A, this is the firmest grade in the 20x30mm M6 range — carry higher loads with less movement than 45 or 60 Shore A grades. Choose 70 Shore A where positional stability, shock restraint, or heavier cyclic loading are the governing requirements rather than maximum vibration isolation.
A. It is suited to construction and off-highway equipment, agricultural machinery, commercial vehicles, power generation plant, marine structures, railway applications, and industrial machinery where a firm end-stop or impact buffer is required.
A. Bonding the rubber element directly to the metal insert means the buffer absorbs and dissipates impact energy without fastener loosening or progressive creep under repeated loading.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, plus additional and custom sizes, are available on request.
A. The 20x30mm M6 format is also available in 45 Shore A (SKU 2030FFB06-45) and 60 Shore A (SKU 2030FFB06-60). Larger formats include SKUs 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16 and 10060FFB16.
