I don’t know what torque the set screw should require.

What torque is required for the set screw of the graphite bearing in Dalian Empire shield pumps? I’ve already damaged one of the graphite bearings; I’m not sure what torque is required for the set screw.
The specific torque value must be determined based on the model of the Dalian Empire shielded pump and the specifications of the graphite bearings. It is recommended to consult the pump’s user manual or contact the manufacturer for accurate information. If there is no manual, you can also ask professional technicians. Avoid damage caused by excessive torque. .
The set screw is used to prevent the sliding bearing from rotating, right? It’s not necessary to tighten the set screw too much; just ensuring rotation prevention is sufficient.
Just tighten it firmly; usually, the set screw does not come into direct contact with the bearing – there should be a white steel washer in between
I have several shielded pumps and mixers from Dalian Empire here. The set screws serve to prevent the bearings from sliding; they are not needed to apply a tightening force like FLANGE bolts do in order to prevent leaks
