Product Number: 3012MFB20-70
Carrying a maximum load of 201.0 kg with a controlled deflection of just 3.25 mm, the 3012MFB20-70 is a 30 x 12 mm male flat buffer built for applications where heavier loads demand firm, predictable resistance and minimal movement. Its M8 x 20 thread and compact flat-face profile allow straightforward installation against a surface or secondary component, making it well suited to situations where the buffer must hold a structure securely rather than permit generous travel. Constructed with a rubber-to-metal bonded design, the 70 Shore A compound delivers the higher load-bearing capacity associated with firm-grade rubber, absorbing and dissipating impact energy while restricting deflection to tightly controlled limits. This characteristic makes the 3012MFB20-70 appropriate where shock and impact loads are present and where the protected assembly must be held firmly in position throughout its service life. The low-cost male flat form factor reduces installation complexity and is effective both as a direct elastic contact element and as a secondary impact cushion. The 3012MFB20-70 serves industries including construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence. Typical equipment applications span construction machinery, industrial plant, agricultural equipment, commercial vehicles, and elevators where firm rubber buffers are required to resist higher impact forces. Custom variants in stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for specialist environments.

A. The 3012MFB20-70 has a maximum load capacity of 201.0 kg.
A. The rated deflection for the 3012MFB20-70 is 3.25 mm, reflecting the firm, low-movement characteristics of a 70 Shore A compound under load.
A. The buffer body measures 30 mm diameter by 12 mm height (D x H), with an M8 x 20 mm male threaded stud (d x L).
A. A 70 Shore A rating indicates a firm rubber compound. Compared with softer grades, it carries higher loads with less deflection, making it the appropriate choice when the buffer must resist substantial impact forces and hold the assembly firmly rather than allow significant movement.
A. The male flat buffer family is designed for construction and off-highway equipment, agricultural machinery, industrial plant, commercial vehicles, elevators, power generation equipment, marine applications, railway and mass transit, automotive, and military and defence applications.
A. Yes. The 30 x 12 mm M8 family is also offered in 45 Shore A (3012MFB20-45) and 60 Shore A (3012MFB20-60). Additional male flat buffer sizes include 0808MFB06, 100100MFB44, 10030MFB41, 10040MFB44, 10050MFB41, and 10055MFB44.
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
