Product Number: 5021FFB10-70
Variations
With a rated maximum load of 723 kg with a controlled deflection of just 5 mm, the 5021FFB10-70 is the firm-grade option in the 50x21mm Female Flat Buffer range, engineered specifically for applications where components must be held securely under substantial force and movement must be kept to a minimum. At 70 Shore A, this buffer is the right choice when compressive loads are high, impact shocks are severe, or the mounted assembly cannot be permitted to shift appreciably under load. Constructed with rubber-to-metal bonded technology, the 5021FFB10-70 absorbs and dissipates energy on contact, protecting both machinery structure and surrounding components from the cumulative damage of repeated shock loading. The M10 female thread allows direct, tool-accessible fastening without additional hardware, and the 50 mm diameter flat face ensures broad, stable contact with mating surfaces. The 70 Shore A compound carries peak loads with minimal give, characteristics that suit it to restraint and bump-stop duties where softer grades would permit excessive travel. At this hardness grade, the buffer is well suited to construction plant, off-highway equipment and industrial machinery operating under heavy cyclical loads, as well as commercial vehicles and agricultural equipment exposed to high-impact service conditions. It also serves in power generation and marine environments where structural integrity under shock is a priority. Where isolation sensitivity is the primary concern rather than load capacity, the 45 Shore A (5021FFB10-45) or 60 Shore A (5021FFB10-60) variants within this geometry provide progressively greater deflection at lower loads.

A. The 5021FFB10-70 Female Flat Buffer is rated to a maximum load of 723 kg and has a deflection of 5 mm, making it the firm-grade option in this geometry for applications requiring high load capacity with minimal movement.
A. At 70 Shore A, this is the firmest grade in the 50x21mm flat buffer range. Harder grades carry higher loads with less movement, so this buffer is suited to heavy-load restraint, impact absorption, and situations where the mounted assembly must not shift significantly under compressive force.
A. The buffer uses an M10 female thread, allowing direct fastening to a compatible male-threaded stud or bolt without additional hardware.
A. This firm-grade buffer is suited to construction and off-highway equipment, industrial machinery, agricultural equipment, commercial vehicles, power generation, and marine applications — particularly where components are subject to heavy cyclical loads or high-impact service conditions.
A. The rubber-to-metal bonded construction absorbs and dissipates energy on contact, cushioning machinery against impact shocks from external moving components and protecting both the machine structure and surrounding components from repeated shock loading.
A. Yes — the 50x21mm M10 geometry is also available in 45 Shore A (5021FFB10-45) and 60 Shore A (5021FFB10-60) for applications requiring greater deflection at lower loads. Larger Female Flat Buffer formats include the 100x100mm M16 (100100FFB16) and 100x30mm to 100x60mm M16 variants. Custom sizes, stainless steel metalwork, and specialist rubber compounds are available on request.
A. Rubber flat buffers of this type may be loaded in shear, compression, or a combination of both, depending on the installation geometry and the direction of the applied force.
A. Yes — stainless steel metalwork, oil-resistant rubber, high-temperature rubber compounds, and additional or custom sizes are available on request.
