The release bearing aids and facilitates the changing of speed of an automobile so that power can also be regulated. It is located in the clutch hub and near the transmission housing. During the process of changing speed, the clutch will attempt to engage and the release bearing will move sideways from the Mazda pressure plate. The pressure plate will be able to drive its springs against the clutch disk and is in turn pushed into the flywheel. Once fully engaged, the release bearing will stop moving and the change in speed is effectuated. The other feature of the Mazda Release Bearing is its ability to interrupt power supply, especially during collision, whether minor or major. During collision, it is important that the engine be stopped immediately to prevent the risk of fire or explosion. There might be some leaks in the fuel when collision happens, so the engine should be stopped because it may ignite the leaking fuel. This specific function of the release bearing makes it a vital safety feature in the vehicle.
Since the Mazda Release Bearing is constantly exposed to friction, it should be regularly lubricated so that it can perform its task efficiently. Most bearings need regular lubrication and there is no such thing as lubed-for-life bearings. Drivers of vehicles which are usually subjected to watery road conditions must ensure that the release bearings of the auto are regularly inspected. Water can dilute lubricants and they will be removed when the parts that they lubricate become submerged to water. Most off-road vehicles are exposed to this kind of condition, so their release bearing should be inspected every after off-road travel.
