Assembly of the copper bushing at the connecting rod pin end

2019-10-09View Original

Thread Content

The copper bushings at the connecting rod ends are assembled using liquid nitrogen cooling. Given that the temperature of liquid nitrogen is extremely low, at over -190 degrees, will this affect the performance of the copper bushings? The cooling temperature for rolling bearings is not lower than -80 degrees℃

Both heating and freezing setups are available. However, it must not be assembled according to standards other than those specified in the instructions.

Setting the time and calculating the freezing temperature is not a difficult task.
