With a rated maximum load of 247.0 kg with a deflection of 7.5 mm, this 50 x 30 mm male flat buffer (SKU 5030MFB25-45) is built for applications where vibration isolation takes priority over load restraint, making it the preferred choice when compliance and movement absorption matter most. At 45 Shore A, it is the softest grade in this geometry, delivering greater deflection under load and superior isolation performance at lower frequencies, precisely where sensitive or lightly loaded equipment demands it most. Rubber-to-metal bonded construction gives the buffer its characteristic combination of structural integrity and elastic compliance. The M10 x 25 male stud allows straightforward bolted installation, keeping fitment quick and repeatable across a range of mounting configurations. Energy is absorbed and dissipated through the rubber element itself, reducing transmitted shock and vibration to connected structures without the need for complex damping systems. At 45 Shore A, this buffer is well suited to construction equipment, agricultural machinery, elevators, and commercial vehicles where the primary requirement is cushioning lighter impact shocks or isolating lower-frequency vibration from sensitive components. It is equally applicable across power generation, marine, railway and mass transit, and military and defence environments. As a low-cost shock and vibration absorption solution, it acts as an elastic element in direct contact with a surface or reduces impact force from a secondary moving object. Custom stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request for specialist installations.

A. This buffer has a maximum load rating of 247.0 kg and a deflection of 7.5 mm under load.
A. At 45 Shore A, this is the softest grade available in this geometry. Softer grades give greater deflection and better vibration isolation at lower loads, making this buffer the right choice where isolation performance and compliance take priority over load restraint.
A. The rubber element measures 50 mm diameter by 30 mm height (D x H: 50 x 30). The male stud is M10 with a 25 mm thread length (d x L: M10 x 25).
A. This buffer is suited to construction equipment, agricultural machinery, elevators, and commercial vehicles. It is also used across power generation, marine, railway and mass transit, automotive, and military and defence applications, wherever cushioning of impact shocks or isolation of lower-frequency vibration is required.
A. The rubber element absorbs and dissipates energy from impact shocks and vibration. It can act as an elastic element in direct contact with a surface or reduce impact force from a secondary moving object. Rubber-to-metal bonded construction ensures the element remains securely coupled to the metal stud under repeated loading.
A. Yes. The same 50 x 30 mm geometry is available in 60 Shore A (5030MFB25-60) and 70 Shore A (5030MFB25-70) for applications requiring higher load capacity with less movement. Additional sizes are listed under SKUs 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.
