Preparation Work Before Installation Of IKO Bearings

IKO bearings should be installed in a dry, dust-free room as much as possible and away from metal processing or other equipment that generates metal debris and dust. When it is necessary to install a bearing in an unprotected environment (which is often the case with larger bearings), appropriate measures must be taken to protect the bearing and associated components from contamination such as dust or moisture until the installation is complete, e.g. Use packing wax paper or foil to cover or wrap bearings and related parts, etc.

Before installation, all necessary parts, tools, equipment and related data should be prepared. Also study the drawings or instructions carefully to determine the correct installation sequence of different components.
Carefully inspect the bearing seats, shafts, seals and other components in the bearing arrangement to ensure that the mating surfaces are clean and good. Special inspection of screw holes, conduits or grooves should be made to prevent the presence of some machining residue. For cast bearing seats, ensure that no core sand remains on some unmachined surfaces and all burrs are removed.
Check the dimensional tolerances and shape tolerances of all components in the bearing configuration. The relevant components must achieve the required accuracy and comply with the specified tolerance range, so that the bearing can perform as it should. The diameter of the cylindrical journal and seat hole is generally measured at two cross-sections and four different positions with a micrometer or an inside micrometer. The taper of the journal can be measured with a ring gauge, a special taper gauge or a sine gauge.
It is recommended to keep records of inspection and measurement results for future reference. When taking measurements, components and measuring instruments should be kept at approximately the same temperature to ensure measurement accuracy. This means that it may be necessary to leave the component and measuring equipment in the same place for a considerable amount of time to reach the same temperature. This approach is especially important for large bearings and related components.
Bearings should be kept in their original packaging until just before installation to prevent dust and other contaminants from entering. Under normal circumstances, there is no need to remove the anti-rust agent applied to the bearings before leaving the factory, just wipe the outer circle and inner hole of the IKO bearing. However, if the bearing is lubricated with grease and is used at very high or very low temperatures or the grease used is not compatible with the anti-rust agent, it is necessary to clean and carefully dry the bearing before installation to avoid damaging the grease. effect.
It is also necessary to clean and dry the bearing before installation if there is a risk of contaminants entering the bearing due to improper handling (e.g. damaged packaging). Bearings taken out of their original packaging also need to be cleaned and dried if the anti-rust agent on the surface is relatively thick or has high viscosity. This may happen to some extra large bearings with an outer diameter greater than 420mm. In this case, you can use petroleum solvent or paraffin wax to remove the anti-rust agent on the bearing.
