The outer diameter of the pump shaft is 60 mm, so what should be the inner diameter of the shaft sleeve for the mechanical seal? Processing requirements

It’s about torque and force, right? What specific data is still needed?
Reply to 1# maradona0901: The inner diameter of the sleeve corresponds to the shaft diameter at the sealing chamber of the pump shaft; attention must be paid to the tolerance fit. The outer diameter of the sleeve varies depending on the installation dimensions of the mechanical seal.
Reply to 2# zhouhuafeng: What is the appropriate clearance value?
Reply to 1# maradona0901: It should be matched as G7/h6 in accordance with API682 standards
Reply to 3# strong1125: **The standard is to give priority to shaft sleeves with a tolerance of F7; followed by G7, and then H7. Given the actual manufacturing capabilities in China, I recommend using R7. The above values are based on the shaft as the reference point, which is also known as the master axis system
For shafts with a diameter of 60mm, a negative tolerance of 0.02–0.03 is usually applied during manufacturing. When it comes to shaft sleeves, the diameter is definitely above 60mm; it’s around 60.03–60.05. In general, the base perimeter system is used
Reply to 7# shijianyanan: The most important issue is that there is no key on the shaft. What are the tightening torques for the shaft sleeve and the shaft?
I’ve learned, I’ve seen it, hehe
