Registration The support units consist of a ball bearing integrated in a housing, of various shapes. Using screws and bolts, the unit is mounted on a machine and the bearing is fixed to a shaft. This means that the support units can be used without the need to design a specific bearing housing. A large variety of housings are available, in standardized shapes and sizes. If the outer surface of the bearing is spherical, the inner surface of the housing will also be spherical, so that the unit can self-align and compensate for any misalignment of the shaft. The bearings are generally pre-lubricated with appropriate grease and equipped with suitable protective seals, in oil-resistant synthetic rubber, mounted on the sides of the bearing with a shield. Depending on the type, the following methods are used for locking the inner ring to the shaft: - It is held in position on the shaft at two points of contact, by means of locking screws. - Using its conical hole it is coupled to the shaft by means of an adapter sleeve. - By means of an eccentric ring which acts on an eccentric groove positioned on one side of the ring itself. There are maintenance-free support units that are used for long periods, thanks to the high-quality lithium-based grease. The sealing system is also used for long periods to prevent grease from escaping and water and dust from entering the outside. The rotation of the shaft causes the circulation of the grease inside the bearing, effectively guaranteeing the maximum lubricating power. The following are the advantages of the maintenance-free bearings of the support units described above: - An adequate quantity of good quality grease is inserted during the production phase, saving time and maintenance costs. - Given the lack of relubrication devices and channels, the unit is more compact. - The presence of the sealing device eliminates the possibility that the grease escapes and deposits on the outside.
