Product Number: 3030MFB20-70
With a rated maximum load of 106.5 kg with a controlled deflection of just 7.50 mm, the 3030MFB20-70 is a 30 x 30 mm Male Flat Buffer with an M8 x 20 mm stud, vulcanised in 70 Shore A rubber for applications where structural firmness and minimal movement under load are the primary requirements. At the harder end of the flat buffer range, this grade is the preferred choice when the mounting point must resist displacement under heavier loads, repeated shock, or impact force, holding the assembly firmly rather than yielding to it. Male Flat Buffers absorb and dissipate energy between machinery and adjacent moving components, reducing transmitted impact force and protecting surrounding structures. The rubber-to-metal bonded construction ensures consistent load-path integrity, while the single-stud male fitting allows straightforward installation without specialist tooling. As the family source confirms, harder Shore A grades carry higher loads with less movement than softer alternatives, a characteristic this 70 Shore grade embodies at the upper bound of the 30 x 30 mm platform. The 3030MFB20-70 is suited to heavy-duty mounting positions in construction equipment, industrial machinery, commercial vehicles, and agricultural equipment where the buffer must restrain rather than isolate, acting as a firm elastic stop against shock or sustained compression. It also serves power generation, marine, and railway applications where structural robustness is valued over compliance. Custom options including stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request.

A. The buffer measures 30 mm diameter by 30 mm height (D x H), with an M8 x 20 mm male stud (d x L).
A. The 3030MFB20-70 is rated to a maximum load of 106.5 kg with a deflection of 7.50 mm — figures reflecting the firm, high-load characteristics of the 70 Shore A rubber grade.
A. As confirmed in the product family data, harder Shore A grades carry higher loads with less movement than softer grades. The 70 Shore A rubber in this buffer provides maximum load resistance and minimal deflection, making it suited to applications requiring firm restraint rather than high isolation or compliance.
A. The 3030MFB20-70 is suited to construction equipment, industrial machinery, commercial vehicles, and agricultural equipment. It also serves power generation, marine, and railway and mass transit applications where robustness under shock or sustained load is the priority.
A. Male Flat Buffers absorb and dissipate energy between machinery and adjacent moving components, cushioning impact shocks, reducing transmitted force, and protecting surrounding structures. The rubber-to-metal bonded construction maintains load-path integrity throughout the service life.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
A. Yes. The same 30 x 30 mm Male Flat Buffer is available in 45 Shore A (SKU: 3030MFB20-45) and 60 Shore A (SKU: 3030MFB20-60) for installations requiring greater deflection and better vibration isolation at lower loads.
