With a rated maximum load of 140.0 kg with a controlled deflection of just 4.25 mm, this 25 x 17 mm Female Flat Buffer (SKU: 2517FFB06-70) is the firm-grade choice within the flat buffer range, built for applications where the mount must hold its position under heavy loads, repeated shock, and sustained impact forces. The M6 female thread makes for straightforward installation without additional hardware, and the rubber-to-metal bonded construction ensures reliable energy absorption at the higher end of the load spectrum. At 70 Shore A, the rubber compound is calibrated to carry significant load whilst minimising movement, making this buffer the appropriate selection where structural restraint matters as much as vibration isolation. The flat buffer geometry works by absorbing and dissipating energy on contact, cushioning machinery against impact shocks from external moving components. Compared with the softer 45 Shore A and 60 Shore A variants in this family, the 70 Shore A grade sacrifices maximum deflection travel in favour of load capacity and positional firmness, precisely the trade-off required in heavier-duty or shock-prone environments. Typical applications include construction equipment, commercial vehicles, agricultural machinery, and industrial plant where mounts are subjected to high compressive or combined shear-and-compression loading. The buffer also suits elevator installations and power generation equipment where controlling the movement of heavy components is a primary concern. Industries served by this family include construction and off-highway, marine, railway and mass transit, automotive, and military and defence.

A. This buffer has a maximum load rating of 140.0 kg and a deflection of 4.25 mm, making it the firm-grade option within the 25 x 17 mm M6 flat buffer family.
A. A 70 Shore A hardness rating places this buffer at the firmer end of the range. It carries higher loads with less movement compared with softer grades, making it suited to applications where positional restraint and resistance to shock are priorities over maximum deflection travel.
A. The buffer measures 25 mm diameter by 17 mm height and features an M6 female thread. These dimensions correspond to the compact flat buffer format within the range.
A. This firm-grade buffer is suited to construction equipment, commercial vehicles, agricultural machinery, industrial plant, elevator installations, and power generation equipment — particularly where mounts must control the movement of heavy or shock-loaded components. Industries served include construction and off-highway, marine, railway and mass transit, automotive, and military and defence.
A. The flat buffer uses rubber-to-metal bonded construction. It works by absorbing and dissipating energy on contact with an external moving component, cushioning the machinery against impact shocks and reducing the force transmitted to surrounding structures.
A. Yes. The same 25 x 17 mm M6 flat buffer is available in 45 Shore A (SKU: 2517FFB06-45) and 60 Shore A (SKU: 2517FFB06-60). Softer grades offer greater deflection and improved isolation at lower loads, whilst the 70 Shore A grade is the appropriate choice where load capacity and minimal movement are required.
A. Yes — custom sizes, stainless steel metalwork, and oil-resistant or high-temperature rubber compounds are available on request.
A. We accept all major credit and debit cards, along with PayPal.
