Avoidance of contaminants is essential for optimum performance and durability of your IKV fluorinated lubricants. The cleaning and preparation area should be clean and free from dust and potential contaminants.
In order to ensure optimum adhesion of the grease to the bearing surfaces, preparation of the substrate is required to include cleaning/ removal of other non fluorinated oils and corrosion protective coatings and protection of the bearings surfaces with a compatible fluorinated anti-corrosion reinforced coating.
By definition, the bearing is a built in or attached mechanical part, often standardised and designed to transfer movements, forces and torques with an excellent degree of effectiveness.
Bearings comprise rolling parts (balls, rollers, needles...) and where necessary are in sealed and additional cages or rolling rings.
Expansion gaps are specified by categories:
Cages are generally made of steel, but may be plastic or a cooper alloy. The latter two materials are larger and tend to rub more on the revolving body.
On the other hand they are more commonly used and the amount of lubricants to be added requires adjustment. This also applies when there are no cages on full complement bearings.
Bearings may be supplied sealed. Theses seals are called Z (shield on one side) or ZZ (shields on both sides) for metal seals or RS or 2 RS for synthetic material shields.
The bearing is selected by the equipment’s manufacturer according to operating conditions, assembly and available space. The type of bearing is mainly defined by the loads applied and the rotation speeds.
Bearings have an expansion gap in accordance with their operating temperatures to maintain as the parts expand.
Rings are also heat treated to ensure that the size of the parts remains stable during high temperature stressing.
These bearings are subject to a range of physical or environmental stresses and must ensure the proper the most effective operation of the material for the longuest period of time and at a proper operating noise level. In order to do this, the choice of lubricant is particularly important and requires the following:
