Where machinery demands firm resistance to heavy impact and minimal deflection, the Male Flat Buffer 25x20mm M6x18 70 Shore A (SKU: 2520MFB18-70) delivers a rated maximum load of 126.0 kg with a controlled deflection of just 5.0 mm, the firmest grade available in the 25x20mm flat buffer family, designed to hold components securely under shock and sustained compressive force. Constructed with rubber-to-metal bonded technology, this 70 Shore A buffer absorbs and dissipates energy without allowing the excessive movement that softer grades permit. Its compact 25 mm diameter and 20 mm height are paired with an M6x18 male stud for straightforward installation against a mating surface. The harder rubber compound is specifically suited to applications where a secondary object must be arrested firmly or where vibration isolation must not compromise positional rigidity. At this hardness grade, the emphasis shifts from compliance to restraint: the buffer acts as a robust elastic stop rather than a soft isolation element, making it appropriate where deflection must be minimised and load capacity prioritised. This buffer serves construction equipment, industrial machinery, commercial vehicles, agricultural equipment and elevators, as well as marine, railway, power generation, automotive and military and defence applications. It performs under compression, shear or a combination of both, and helps improve machinery lifespan, protect surrounding structures and maintain operator comfort under demanding duty cycles. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for specialist environments, as are additional and custom sizes.

A. The 2520MFB18-70 has a rated maximum load capacity of 126.0 kg, making it the firmest grade in the 25x20mm flat buffer family and suited to heavier compressive and shock loads.
A. At the 70 Shore A hardness grade, deflection is limited to 5.0 mm at maximum rated load. This low deflection characteristic means the buffer holds components firmly with minimal movement — appropriate where positional rigidity is required alongside shock absorption.
A. The buffer body measures 25 mm diameter by 20 mm height. The male stud is M6 with an 18 mm thread length.
A. The 70 Shore A grade is designed for heavier loads, shock and impact duty, and installations where the component must be held firmly with minimal deflection. Confirmed application sectors include construction equipment, industrial machinery, commercial vehicles, agricultural equipment, elevators, marine, railway, power generation, automotive, and military and defence.
A. Harder rubber grades carry higher loads with less movement, whereas softer grades give greater deflection and better vibration isolation at lower loads. The 45 Shore A (2520MFB18-45) and 60 Shore A (2520MFB18-60) variants are available where compliance and isolation are the priority over load restraint.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes beyond the standard catalogue range.
A. We accept all major credit and debit cards, along with PayPal.
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.
