Suspension Bush - Inner Dia 25.4mm, Outer Dia 88.9mm, L 66.7mm - ECC1165-45

Sensitivity to vibration and a need for maximum isolation define the application territory of the ECC1165-45-45, a 45 Shore A eccentric bush with a 25.4 mm inner diameter and overall dimensions of 88.9 mm (B) × 66.7 mm (C) × 79.4 mm (D), the smallest and lightest-duty position in this eccentric bush range. At this softer hardness grade, the rubber compound is optimised to yield greater deflection under load, making this bush the right choice where isolating low-frequency vibration matters more than restraining movement, and where surrounding structures or operators need protecting from transmitted shock. The rubber-bonded inner-outer-sleeve construction bonds the elastomer directly between machined metal sleeves for high durability under dynamic loads and prolonged service life. The 45 Shore A compound delivers a primary stiffness of 475 N/mm, a secondary (F2) stiffness of 640 N/mm, and a maximum deflection of 3.8 mm at a maximum rated load of 185 kg, figures that place it firmly in lighter, compact or sensitive installations where deflection is a design asset rather than a liability. Because the rubber-to-metal bond carries the load, no lubrication is required and the bush is entirely maintenance free throughout its service life. Suitable for loaded conditions in shear, compression or a combination of both, the ECC1165-45-45 serves industries including agriculture, power generation, marine, and automotive, with further application potential in pivot bearings, mechanical linkages and cab mounts on lighter or vibration-sensitive equipment.

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).
