[Issues with Bearing Installation Method] Shrink Fitting Method Gas Burner

Introducing the advantages and disadvantages of the shrink fitting method using a gas burner!

We will introduce the issues with the method of installing bearings using a gas burner. The outer flame of an acetylene gas burner used for welding reaches 3200°C, and even a propane gas burner used for road repairs and weed burning can reach 1500°C. It requires skilled technique to heat the bearing uniformly. This method has a high likelihood of causing uneven thermal expansion and material changes. Additionally, temperature management is difficult, so if the bearing temperature rises above 120°C, the oxidation of the grease can shorten the lifespan of the bearing. 【Advantages】 ■ No size limitations for heating ■ Fast heating *For more details, please refer to the related link page or feel free to contact us.
