The key points of the roller accessories must be grasped during the installation process, and the roller accessories can exert its own value only after the roller accessories are effectively installed. Roller accessories SKF bearings are also shortened in the width direction during cooling, so a certain pressure must be applied to press the inner ring to the shoulder during installation, and after cooling, use a very thin feeler gauge to test whether the end face of the inner ring There is a gap between the shaft shoulder. It is found that the required heating temperature is reached, and the device must be carried out as soon as possible to avoid cooling and causing difficulties in the device. The heating temperature should be controlled properly. If the temperature is too high, SKF bearings will be damaged. If the temperature is too low, the ring expansion will be insufficient, and the effect will not be significant. When the temperature is small, the thermal expansion of the inner diameter of the inner ring obtained from the heating temperature of 80-1000°C is large, which is sufficient for SKF bearings with general interference.
The external environment has a great influence on the roller accessories. You can choose the appropriate roller accessories according to the actual situation; select the appropriate roller accessories according to the manufactured roller. For example, what kind of accessories are suitable for nylon rollers; what kind of accessories should be selected for rubber rollers, etc.; the manufacturing process is a big aspect that should be paid attention to when selecting accessories.
