The CV joint bellow is a special protective cover made of elastic material, resistant to aggressive environments, capable of adapting to various temperature conditions. The bellow protects the outer and inner joints of equal angular velocities from the ingress of dirt and water, prevents the loss of lubricants.

Front-wheel drive vehicles are equipped with special devices called constant velocity joints (CV joints). To ensure that the wheels of the car turn between the semi-axle and the front wheels, swivel joints are installed. Two such mechanisms are installed on each wheel of the vehicle - an internal and an external one.

The functionality of the Metalcaucho brand Bellow, drive shaft

In order to protect the above-mentioned devices from dust, dirt, small pieces of asphalt, water and other foreign impurities from entering the mechanism, bellows are installed. Two bellows (inner and outer) are attached to each CV joint of the wheel. These elements prevent premature wear of the CV joint and significantly extend the service life of its operation.
