Product Number: 7040FFB12-45
Variations
Where low-frequency vibration isolation takes priority over restraint, the 7040FFB12-45 Female Flat Buffer delivers. Measuring 70 x 40 mm with an M12 female thread and moulded to a 45 Shore A hardness, this rubber-to-metal bonded unit is engineered specifically for lighter or sensitive equipment where the mount must absorb and dissipate energy whilst permitting maximum movement under load, a rated 10 mm deflection at up to 505 kg. That combination places this buffer at the soft end of the flat-buffer hardness spectrum, making it the appropriate choice wherever cushioning compliance matters more than positional restraint. The rubber-to-metal bonded construction ensures the elastomer and metal insert remain mechanically integrated throughout the service life of the mount. A female threaded insert allows clean bolt-up installation against a mating fastener, keeping the assembly low-profile and the installation straightforward. Because the softer 45 Shore A compound yields more readily under applied force, it offers superior isolation efficiency at lower load magnitudes and lower excitation frequencies, conditions typical of conveyor end-stops, light agricultural equipment, and access-platform sub-frames. The 70 x 40 mm Female Flat Buffer family is also available in 60 Shore A [7040FFB12-60] and 70 Shore A [7040FFB12-70] for heavier loads or firmer restraint. Larger flat-buffer formats are offered in the 100 mm diameter range: 100 x 30 mm [10030FFB16], 100 x 40 mm [10040FFB16], 100 x 50 mm [10050FFB16], 100 x 55 mm [10055FFB16], 100 x 60 mm [10060FFB16], and 100 x 100 mm [100100FFB16], all M16 thread.

A. This buffer measures 70 mm diameter by 40 mm height, features an M12 female thread, has a maximum load rating of 505 kg, and provides up to 10 mm deflection under that load.
A. The 7040FFB12-45 is moulded to 45 Shore A — the softest grade in this flat-buffer family. Softer grades yield greater deflection and deliver better vibration isolation at lower loads and lower excitation frequencies, making this grade well suited to lighter or sensitive equipment where isolation efficiency is more important than positional restraint.
A. The buffer is suited to construction equipment, industrial machinery, agricultural equipment, commercial vehicles, elevators, and sectors including power generation and marine. It performs in compression, shear, or combined loading — acting as a cushion against impact shocks from external moving components or as an elastic contact element.
A. It uses rubber-to-metal bonded construction, permanently integrating the elastomer with the metal insert. The M12 female threaded insert allows direct bolt-up installation against a mating fastener, keeping the assembly compact and installation straightforward.
A. The 70 x 40 mm M12 Female Flat Buffer is also available in 60 Shore A [7040FFB12-60] and 70 Shore A [7040FFB12-70] for increased load capacity and reduced deflection. Larger 100 mm diameter M16 variants include 100 x 30 mm [10030FFB16], 100 x 40 mm [10040FFB16], 100 x 50 mm [10050FFB16], 100 x 55 mm [10055FFB16], 100 x 60 mm [10060FFB16], and 100 x 100 mm [100100FFB16].
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
A. Standard UK mainland delivery is 3–5 working days. Next-day delivery is available on most products and will appear as an option at checkout where eligible.
