Induction heating provides the best answer in terms of safety, cleanliness and speed. This technique is more suitable than heating by oil bath, hot plate or oven.

NTN designs, develops, manufactures and markets various ranges of bearings, rollers, linear guides, CV joints, coders, vehicle spare parts, maintenance products... and offers related services. We support the major players on a global scale and also provide distribution and aftermarket services.

Moreover, the heating temperature depends on the dimension of the bearing, the required fit and the material of the shaft. The temperature should not be too high (130 °C maximum), otherwise the characteristics of the steel or the internal components of the bearing may be compromised.

NTN-SNR has developed its SERVICES range (such as technical support, training) to increase your skills and optimize your maintenance costs.

To make mounting easier, and to avoid fretting corrosion of the shaft or housing, we recommend you always use an anti-fretting paste. This thick lubricant maintains the surface quality of the parts that are subjected to sliding forces. Without this paste, corrosion gradually increases the clearence between the bearing and the shaft (or housing). Over time, this would lead to vibrations or even the premature deterioration of the bearing and mounting surfaces.

Hot mounting is customary when the fitting of a bearing onto a shaft requires a large press force, either due to its size or its high interference fit.

Hydraulic assistance is required for the mounting of large bearings with a tapered bore. This requires considerable force, which is difficult to achieve by mechanical screw clamping.

Please do not clean the bearings (unless specified on the leaflet). They are protected from oxidation by a light oil film, compatible with all lubricants.

Special case of mounting on a long shaft requiring a positional adjustment of the bearing: it is adviseable to use a tapered bore bearing in conjuction with an adaptor sleeve.
