Product Number: 5021MFB25-60
Variations
Carrying a maximum load of 514.0 kg with a controlled deflection of 5.3 mm, the 5021MFB25-60 is a 50 x 21 mm Male Flat Buffer rated at 60 Shore A, a medium hardness that balances vibration isolation against the structural support demanded by heavier industrial applications. The M10 x 25 threaded stud allows straightforward fitment into existing metalwork without specialist tooling, making this a practical choice wherever robust bump-stop or elastic-element performance is required across the broad middle ground of machinery mounting. Constructed with rubber-to-metal bonding, this flat buffer absorbs and dissipates energy on impact, reducing the force transmitted between a moving component and its surrounding structure. At 60 Shore A, deflection is kept to a firm 5.3 mm under peak load, ensuring predictable positional control while still offering meaningful isolation, a characteristic particularly well-suited to heavy industrial machinery, power generation plant, and commercial vehicle mounting where both load-bearing and damping performance are needed simultaneously. The low-profile flat-face geometry places the rubber directly in contact with the secondary surface, delivering efficient energy transfer with minimal installation complexity. Applications drawing on this balance of load capacity and isolation include construction equipment subject to sustained operational loads, agricultural machinery requiring reliable chassis mounting, and elevator buffer duty where controlled deceleration under higher mass is a requirement. The rubber compound is available in oil-resistant and high-temperature variants, and stainless steel metalwork is offered on request, extending suitability to marine, railway, and demanding off-highway environments.

A. This buffer has a maximum load rating of 514.0 kg and a deflection of 5.3 mm, as specified in the product technical data.
A. The buffer body measures 50 mm diameter by 21 mm height (D x H: 50 x 21). The threaded male stud is M10 with a 25 mm shank length (d x L: M10 x 25).
A. At 60 Shore A, this medium hardness grade provides a balance between load-bearing capacity and vibration isolation. Softer grades (such as 45 Shore A) offer greater deflection and better isolation under lighter loads, while harder grades (such as 70 Shore A) carry higher loads with less movement. The 60 Shore A grade suits the broad middle ground where both structural support and damping are required.
A. Male Flat Buffers in this family are applied across construction equipment, industrial machinery, agricultural equipment, elevators, and commercial vehicles. Industries served include construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.
A. The rubber-to-metal bonded construction absorbs and dissipates energy on impact, cushioning machinery against shock loads and reducing force transmission. The male threaded stud (M10 x 25) fastens directly into a threaded hole or nut in the mounting structure. The flat rubber face contacts the secondary surface or component, acting as a bump stop or elastic mounting element.
A. Yes. Within the 50 x 21 mm Male Flat family, 45 Shore A (5021MFB25-45) and 70 Shore A (5021MFB25-70) variants are available. Custom sizes, stainless steel metalwork, oil-resistant rubber, and high-temperature rubber compounds are available on request.
