Carrying a maximum load of 252.0 kg with a controlled deflection of just 6.8 mm, the 4028MFB23-70 is a 40 x 28 mm male flat buffer with an M8 x 23 mm stud, vulcanised in 70 Shore A rubber for firm, load-bearing anti-vibration duty. At this hardness grade, the mount is engineered to hold components positively under heavier static and dynamic loads, making it the appropriate choice where minimal movement and secure retention matter more than maximum isolation travel. Male flat buffers in this family offer low-cost shock and vibration absorption through a rubber-to-metal bonded construction that absorbs and dissipates energy on contact. The flat face design allows the buffer to act as an elastic element in direct contact with a surface, or to cushion machinery against impact shocks from external moving components. Compared with softer grades in this range, the 70 Shore A compound carries higher load with less movement, suited to applications where deflection must be tightly controlled and structural restraint is a priority. The 4028MFB23-70 is well suited to mainstream general-machinery mounting at moderate-to-substantial loads. Source-confirmed application areas include industrial machinery, construction equipment, commercial vehicles, agricultural equipment, and elevators. The rubber-to-metal bond improves machinery lifespan, protects surrounding structures, and contributes to operator comfort. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence. Custom variants in stainless steel and oil-resistant or high-temperature rubbers, as well as additional sizes, are available on request.

A. The 4028MFB23-70 is rated to a maximum load of 252.0 kg with a deflection of 6.8 mm, making it the firmest option in the 40 x 28 mm male flat buffer range at 70 Shore A.
A. A 70 Shore A compound is a firm rubber grade. It carries higher loads with less deflection compared with softer grades, making it suited to applications where components must be held securely under heavier or dynamic loads with minimal movement.
A. The buffer body measures 40 mm diameter by 28 mm height (D x H: 40 x 28). The male stud is M8 with a length of 23 mm (d x L: M8 x 23).
A. Source-confirmed applications include industrial machinery, construction equipment, commercial vehicles, agricultural equipment, and elevators. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. The male flat buffer uses a rubber-to-metal bonded construction. It works by absorbing and dissipating energy — either cushioning machinery against impact shocks from external moving components or acting as an elastic element in direct contact with a surface.
A. Yes. The same 40 x 28 mm male flat buffer with M8 stud is available in 45 Shore A (SKU: 4028MFB23-45), which gives greater deflection and better isolation at lower loads, and 60 Shore A (SKU: 4028MFB23-60) for a mid-range balance of load capacity and deflection.
A. Yes. Stainless steel metalwork and oil-resistant or high-temperature rubber compounds, as well as additional and custom sizes, are available on request.
