Product Number: 1520FFB04-70

With a rated maximum load of 32.0 kg with a controlled deflection of just 5.0 mm, the Female Flat Buffer 1520FFB04-70 is the firmest option in this 15 x 20 mm M4 mounting geometry, purpose-built for applications where structural rigidity and minimal movement under load take priority. The 70 Shore A rubber grade ensures the buffer holds its position firmly under heavier forces, making it the appropriate choice where shock and impact must be arrested decisively rather than absorbed through large deflection travel. Rubber-to-metal bonded construction gives the buffer its structural integrity under compressive and shear loading. The female M4 thread offers a clean, direct fixing point, simplifying installation on equipment panels, chassis rails, and structural members. Energy is absorbed and dissipated through the rubber element itself, cushioning connected structures against the repeated impact forces generated by external moving components, thereby improving machinery lifespan and protecting surrounding structures from cumulative fatigue damage. At this hardness grade, the buffer is well suited to construction and off-highway equipment, agricultural machinery, commercial vehicles, and industrial plant where components must be restrained positively against shock loads rather than allowed significant compliance. Marine, railway, and power generation applications requiring firm, high-load buffer points at compact M4 fixing centres will also benefit from this specification. Where oil-resistant or high-temperature rubber compounds are required, or where stainless steel metal parts are needed, custom variants are available on request.

A. This buffer has a maximum load rating of 32.0 kg and a deflection of 5.0 mm, making it the firmest option in the 15 x 20 mm M4 range with minimal movement under load.
A. At 70 Shore A, this is a firm-grade rubber. It carries higher loads with less deflection compared to softer grades, making it suitable for applications requiring positive shock restraint and minimal compliance rather than large-deflection vibration isolation.
A. This buffer is suited to construction and off-highway equipment, agricultural machinery, commercial vehicles, industrial plant, marine, railway, and power generation applications — particularly where components must be held firmly against shock and impact loads at compact M4 fixing centres.
A. The rubber element absorbs and dissipates energy on contact with an external moving component or surface. The rubber-to-metal bonded construction maintains structural integrity under compressive and shear loading, cushioning connected structures and reducing cumulative fatigue damage.
A. Yes. The same 15 x 20 mm M4 geometry is available in 45 Shore A (1520FFB04-45) and 60 Shore A (1520FFB04-60) for applications requiring greater deflection or softer isolation. Larger flat buffer formats — including 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16, and 10060FFB16 — are also available in the range.
A. Yes. Stainless steel metal parts and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
