Product Number: 7540FFB12-70
Variations
Rated at a maximum load of 1,337 kg with a controlled deflection of just 10 mm, the 7540FFB12-70 is the firm-grade variant in the 75x40mm female flat buffer range, built for duty cycles where high compressive load must be resisted with minimal give. The M12 female thread and rubber-to-metal bonded construction allow direct integration into machine frames, chassis rails and structural mounting points where a securely held, impact-resistant buffer is required. At 70 Shore A, this buffer is engineered to hold heavy components firmly in position, resisting displacement under sustained loading and repeated shock events. Harder grades carry higher loads with less movement, making the 70 Shore A the correct selection when softer grades would over-deflect or bottom out. The rubber-to-metal bond dissipates and absorbs impact energy at each strike cycle, protecting surrounding steelwork and extending service intervals. Typical applications include construction equipment subject to repetitive ground-borne impact, industrial machinery requiring positive end-stop restraint, agricultural equipment exposed to sustained compressive loads, commercial vehicles carrying heavy loads over rough terrain, and power generation plant where component displacement must be controlled. The buffer also suits marine and railway environments where high-load shock duty is routine. The 75x40mm M12 female flat buffer is available in complementary hardness grades: 45 Shore A (7540FFB12-45) for maximum isolation and greater deflection, and 60 Shore A (7540FFB12-60) for general-purpose duty. Larger geometry variants in the female flat buffer family include 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16 and 10060FFB16.

A. The 7540FFB12-70 female flat buffer has a maximum load rating of 1,337 kg.
A. The maximum deflection for the 7540FFB12-70 is 10 mm.
A. The buffer measures 75 mm diameter by 40 mm height with an M12 female thread.
A. Harder grades carry higher loads with less movement. At 70 Shore A, this buffer resists displacement under heavy or repeated shock loading where a 45 or 60 Shore A grade would over-deflect. It is the correct choice when firm restraint and maximum load capacity are the priority.
A. The female flat buffer family is designed for construction equipment, industrial machinery, agricultural equipment, commercial vehicles, power generation plant, marine applications and railway environments. The 70 Shore A grade is particularly suited to high-load and impact-duty applications within these sectors.
A. The buffer features rubber-to-metal bonded construction, providing a durable bond between the rubber element and the metal threaded insert to withstand sustained compressive and shock loading.
A. Yes. The 75x40mm M12 family includes 45 Shore A (7540FFB12-45) and 60 Shore A (7540FFB12-60) grades. Larger female flat buffer geometries include 100100FFB16, 10030FFB16, 10040FFB16, 10050FFB16, 10055FFB16 and 10060FFB16.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
