Suspension Bush - Inner Dia 43.7mm, Outer Dia 101.6mm, L 63.5mm - ECC1355-45

Where vibration isolation takes priority over load restraint, the ECC1355-45-45 eccentric bush delivers precisely that balance, a 43.7 mm (dimension A) rubber-to-metal bonded bush rated to 245 kg maximum load with a radial stiffness of 682 N/mm and a maximum deflection of 3.5 mm, characteristics that place this 45 Shore A soft-grade unit at the responsive end of the AV Industrial eccentric bush range. Its lower hardness allows the rubber element to move more freely under dynamic inputs, making it the appropriate choice where reducing transmitted vibration and noise matters more than limiting movement at the mount. Constructed with rubber bonded between inner and outer metal sleeves, this eccentric bush requires no lubrication and is entirely maintenance free. The rubber-to-metal bond is engineered for high durability under sustained dynamic loads and prolonged service life, and the bush may be loaded in shear, compression, or a combination of both. An F2 axial stiffness of 1150 N/mm complements the radial figure, giving designers accurate data for multi-axis installations. With dimensions A 43.7 mm, B 101.6 mm, C 63.5 mm, D 72.4 mm, and E 9.5 mm, the ECC1355-45-45 suits lighter and compact installations where sensitivity to vibration transmission is the design driver. Typical applications drawn from the family include pivot bearings, mechanical linkages, cab mounts, engine mounts, off-road vehicles, construction equipment, and railway and mass transit assemblies. Industries served encompass construction and off-highway, agriculture, power generation, marine, railway and mass transit, automotive, and military and defence.

Eccentric Bushes are manufactured from two metal sleeves which are eccentrically offset in the radial direction. This offset allows for a larger proportion of the rubber section to be orientated in the normal direction of load, allowing for relatively large radial deflections to be achieved, whilst maintaining excellent motional control characteristics.

Eccentric bushes are robust in design, fail-safe, and suitable for ROPS and FOPS cabs (subject to approval).
