Suspension Bush - Inner Dia 24mm, Outer Dia 75.3mm, L 51mm - ECC2174-60

Engineered for the broad middle ground of general machinery mounting, the ECC2174-60-60 is a 24mm eccentric bush rated to a maximum load of 325 kg with a stiffness of 750 N/mm, making it well suited to moderate-load applications where both vibration isolation and structural support must be balanced. At 60 Shore A, this medium-hardness grade sits at the upper end of the standard range, delivering controlled deflection, up to 3.5 mm in the F1 axis. Without compromising the load-carrying capacity that heavier equipment demands. Constructed using a rubber-bonded inner-to-outer metal sleeve configuration, the bush requires no lubrication and is fully maintenance free, ensuring prolonged service life under dynamic loading conditions. The rubber-to-metal bonded build resists fatigue across shear, compression, and combined load orientations, protecting surrounding structures while improving operator comfort. Key dimensions are: A 24 mm, B 75.3 mm, C 51.0 mm, D 70 mm, E 10.5 mm; F2 stiffness is 600 N/mm. The 60 Shore A grade is the practical choice for mainstream industrial environments, including construction and off-highway machinery, power generation equipment, agricultural plant, cab mounts, mechanical linkages, and marine applications. Wherever moderate dynamic loads must be managed without the high deflection associated with softer grades. Its load and stiffness figures make it appropriate for pivot bearings and engine mounts operating under sustained, moderate duty cycles. This bush is part of a wider eccentric and spherical bush family.

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).
