Precautions

■ Precautions When Selecting

Points to note when making a selection

■ Precautions During Installation
If the shaft or bearing housing has poor accuracy, it will affect the bearing and prevent it from performing as it should. For example, poor accuracy at the bearing installation location can cause the inner and outer rings to become misaligned. At this time, in addition to the bearing load, additional edge stress concentration load (Edge Load) will be added, which will shorten the bearing's fatigue life. In more severe cases, it may also cause cage breakage, seizure, and other damage.

Please use the following dedicated installation tools for mounting and removal.

Bearing Heater	Proper installation of the bearing heater can ensure a long service life for the bearing. If properly installed and maintained, rolling bearings are reliable mechanical components with a long service life. After heating with an induction heater, the bearing expands outward in the cylindrical direction, which can prevent damage during installation. The induction heater is the most scientific heating method. It does not require preheating and can heat the bearing to 110°C within a few seconds or minutes depending on the bearing's weight, without damaging the pre-applied lubricant.

Bearing Puller	When the bearing is installed in any of the following conditions, a specialized puller can be used for removal. (a) Shaft shape: cylindrical shaft; bearing inner ring bore shape: cylindrical bore. (b) Shaft shape: cylindrical shaft, using an adapter sleeve; bearing inner ring bore shape: tapered bore. (c) Shaft shape: stepped shaft; bearing inner ring bore shape: stepped bore. Regardless of the condition, when disassembling, you must loosen the lock nut (or adapter sleeve lock nut) on the shaft and set the lock nut to a loose state.
