WASHERS WITH COLLAR

Washers with collar consist of two metal parts, one flat and one with a collar, between which rubber is vulcanised. Washers with collar absorb vibrations by isolating the stresses of through elements (such as screws, bolts, connection pipes) and are used in this way to counter compressive and shear stresses. They can also be mounted opposite each other or with other types of anti-vibration washers (single metal/bi-metal)
Application on agricultural machinery, tractors, off-road machinery and military equipment.
