In order to achieve higher device performance and lowest maintenance cost, reliable running, you must follow the correct approach. This includes bearing storage, removal, cleaning, testing and installation.
Any INA bearing service life and maintenance depends to a large extent on its reception. This in particular in industrial applications, are often poor working conditions, load weight, size of dust and pollution are common.
Applies to all anti-friction bearing designs. INA bearing store has special bearing anti-corrosion coating choices, most bearing corrosion prevented materials manufacturing. In the handling and storage of bearings, care must be taken to ensure that they will not rust or corrode. Even wet or unprotected left hand or a small amount of chemical gloves can cause etching in a small area, which may lead to bearing fatigue.
New and reformed INA bearings of shipment protection coating, usually in a protective cover or other paper packaging, and transport in a cardboard boxes or wooden boxes. When you receive a new or remanufactured bearings, does not remove it from the packaging until ready to install in your application.
Do not store directly on the cement floor, where you can collect and condense water bearing. Pallet or bearing on store shelves, where bearings are not affected by high humidity or sudden and severe temperature changes, may cause condensation to form regions.
Each type of INA bearing design has a unique removal process. Regardless of the bearing type, bearing special care should be deleted. If improper operation, may damage the INA bearings, shaft or casing, requiring expensive repairs. For smaller bearings, a driver can help bearing removal and so on. Fitted with closely, or press, or an axis has been locked in a place, you can't use the machinery dismantled bearing puller, bearing inner rings can be heated to ease relocation. Heat lamps or other heating devices can use. If when a torch, it would change the bearing performance of steel and bearings must be discarded.
To sum up, GCrl5 steel after quenching undissolved carbides in about 7%, around 9% of residual austenite (aphanitic martensite of the average carbon content of around 0.55%) is the best organizations. Moreover, when the original organization of carbides in tiny, when distributed, reliable level of control of the above-mentioned composition microstructure, integrated in favour of high mechanical properties, which has a high service life. It should be noted that has a smaller dispersion of carbide distribution the original organization, when quenching heat insulation, small carbide dissolved flock grows up, making it rough. Therefore, for this original organization bearing quenching heating time should not be too long, using rapid heating of austenite in quenching process, will benefit from more comprehensive mechanical properties.
