A. The FM4020-75 is rated to a maximum load of 17 kg with a deflection of 2.5 mm. These figures reflect the firm 75 Shore A rubber grade, which prioritises load capacity and positional stability over large deflection.
A. The principal dimensions are: A (flange diameter) 40 mm, B (body depth) 20 mm, C (thread) M6, D 19 mm, E 29 mm, F 52 mm, G 64 mm, and H 6.2 mm.
A. The FM4020-75 may be loaded in shear, compression, or a combination of both, depending on the installation requirements.
A. It is suited to construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence applications. At 75 Shore A it is particularly appropriate for heavier ancillary units, impact-exposed assemblies, and installations where firm restraint is required alongside vibration attenuation.
A. The 40 mm capped flanged body is available in three hardness grades: FM4020-45 (45 Shore A, greater deflection and isolation at lighter loads), FM4020-60 (60 Shore A, general-purpose mid-grade), and FM4020-75 (75 Shore A, this product, for higher loads and minimal movement).
A. Yes — stainless steel metalwork and oil-resistant or high-temperature rubber compounds are available on request, as are additional and custom sizes.
