Product Number: 4040MFB25-70
Variations
Rated at a maximum load of 199 kg with a controlled deflection of just 10 mm, the 4040MFB25-70 is the firm-grade variant in the 40x40mm Male Flat Buffer range, engineered for applications where a component must be held positively under heavy load or repeated shock. The 70 Shore A rubber compound delivers the stiffest response in this geometry, making it the appropriate selection where high-load restraint and minimal movement under impact are the primary requirements. Rubber-to-metal bonded construction gives the buffer its structural integrity, bonding the natural rubber element directly to the threaded metal stud (M10 x 25 mm) to resist separation under cyclic loading. The flat buffer geometry is well suited to acting as an elastic contact element between a moving component and a fixed surface, absorbing and dissipating energy at each impact rather than allowing hard metal-to-metal contact. The design is low cost and straightforward to install, requiring only a tapped hole or appropriate fastener to locate the mount in service. At 70 Shore A, this buffer is particularly appropriate for construction equipment, industrial machinery, and commercial vehicles, environments where components carry substantial loads or experience hard shock inputs and where a softer grade would deflect excessively or fail to provide adequate restraint. It is also specified in agricultural equipment and power generation plant where vibration isolation at higher load is required. Custom options including oil-resistant or high-temperature rubber compounds and stainless steel metalwork are available on request for demanding or corrosive environments.

A. This buffer is rated to a maximum load of 199.0 kg with a deflection of 10.0 mm, making it the firmest and highest-load option in the 40x40mm Male Flat Buffer range.
A. At 70 Shore A, this is the firm grade of the range. Harder rubber carries higher loads with less movement, so this grade is suited to applications requiring positive restraint under heavy or shock loading rather than maximum vibration isolation.
A. The buffer body measures 40 mm diameter by 40 mm height (D x H: 40 x 40 mm). The threaded stud is M10 with a 25 mm stud length (d x L: M10 x 25 mm).
A. Applications include construction equipment, industrial machinery, agricultural equipment, commercial vehicles, and power generation plant — wherever components must be restrained under high load or hard shock inputs.
A. The rubber-to-metal bonded construction absorbs and dissipates energy at each impact, preventing hard metal-to-metal contact. It can act as an elastic contact element between a moving component and a fixed surface, reducing impact force and extending machinery lifespan.
A. Yes. The 40x40mm Male Flat Buffer is also available in 45 Shore A (4040MFB25-45) and 60 Shore A (4040MFB25-60). Custom options including oil-resistant or high-temperature rubber compounds and stainless steel metalwork are available on request.
A. In-stock orders placed before 14:30 Monday to Friday are usually dispatched the same day.
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.
