Why is mounting and dismounting important? Correct mounting and dismounting is paramount to get the best performance from your bearings. Mounting Bearings are a key component in any moving machinery and must be handled carefully to ensure they perform to their full potential. Bearings have to be correctly fitted, both onto a shaft and into a housing. This generally means that one ring of the bearing has an interference fit, either on its shaft or in its housing. The specification of these fits is recommended by NSK in its technical catalogues. Consequently, fitting a bearing requires special...

Hydraulic assembly The use of hydraulic tools allows the degree of force needed to ensure the correct fit of larger bearings. This is particularly relevant for bearings fitted to a tapered shaft or sleeve. The NSK range of tools includes hydraulic nuts for axial drive-up methods, hydraulic pumps and hydraulic pullers/extractors. These ensure that high forces are applied evenly and in a controlled manner, allowing easy assembly or removal of the bearing. Hot assembly An alternative to methods involving direct force is the use of heat to expand the bearing rings. This results in an easy sliding...

Interference fits – cylindrical bearing shaft With most bearings, either the inner or the outer ring (in certain cases even both) is mounted onto the shaft or into the housing with an interference fit. Please review NSK’s recommended interference fits. Incorrect mounting During cold mounting of rolling bearings, it has to be ensured that the mounting forces are always applied to the ring with the interference fit. Mounting forces should never be applied through the rolling elements. The raceway may be damaged if force is applied on the wrong bearing ring. Correct mounting The danger of damaging...

Mechanical tools NSK has designed a range of mechanical tools specially designed around its bearings to ensure their fast and efficient fitting and removal. Fitting Tool Kit FTN333 Small and medium bearings are generally cold-mounted. NSK’s fitting tool kit ensures that this is carried out efficiently without damage.
