A. The FM4020-60 is rated to a maximum load of 10 kg with a deflection of 2 mm. These figures reflect the 60 Shore A medium-grade rubber, which provides a balanced response between isolation and load-bearing capacity.
A. At 60 Shore A, this is the medium grade in the 40mm flanged range. It offers more deflection and better isolation than the firmer 75 Shore grade, while carrying higher loads with less movement than the softer 45 Shore grade — making it the general-purpose choice for moderate-load applications.
A. The key dimensions are: A (outer diameter) 40 mm, B 20 mm, C thread M6, D 19 mm, E 29 mm, F 52 mm, G 64 mm, H 6.2 mm.
A. The FM4020-60 is suited to construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence applications. At 40mm it is particularly appropriate for instruments, light equipment, and electronics requiring balanced vibration damping under moderate load.
A. The rubber-to-metal bonded construction allows the FM4020-60 to be loaded in shear, compression, or a combination of both, offering flexibility in how it is fitted within a machine or structure.
A. Yes. The 40mm M6 flanged mount is also available in 45 Shore A (FM4020-45) and 75 Shore A (FM4020-75). The family extends to larger geometries including FM6024, FM8027, FM10028, FM15039, and FM20044. Stainless steel metalwork and oil-resistant or high-temperature rubbers are available on request.
