When you expect good luck, cheaters will have good luck! It is wise to stay away from great bargains!

Hi Daddy SUS, I've seen a lot of responses on this thread from people worried that too much torque will damage the chuck? I am not a professional mechanical practitioner, my early use of chuck is 160mm, using 10*10 keys, now using 200mm, 250mm/300mm chuck, key 11mm,12mm. I don't think I have...

May I request that you test the square dimensions of the inner holes of each chuck? Are you sure these sizes are not using metric keys that are close to the imperial size?

I would like to know whether all your sizes are the metric size of the standard configuration of the chuck or the approximate data after conversion in imperial system? I hope that the size of the tool is just enough to plug in and pull out smoothly. I don't like too much gap, so I hope to have...

I do not know much about the imperial system, but according to the accepted pressure is cost-effective: 1 mpa=10.1971621 kg/cm². Calculate the cylinder diameter of 140mm in my picture, and the calculation result is as follows: 7cm*7*3.14=153.86cm² (cylinder area) *50MPA*10197=78445kg/cm=78.445T...

As I progressed, I found more questions: Solenoid valve electromagnet core can not move, probably because after a long time to stop the use of a little stuck, I can only open and clean up, now the valve body is also easy to use. Another major problem was that the hydraulic cylinder began to...

Your judgment is correct, it is indeed a filter, I have welded the hole with TIG, and it starts to work normally, thank you for your answer!

Is this white part made of aluminum? Below and in the middle is the point of failure. The hydraulic station purchased a few years ago tried to start today, but there was a small hole leaking oil. What is this part and what is its main role? Filter? Or limit voltage insurance? Is it OK to weld...

Recently, I am busy and have little time to take a walk in the forum. When I have difficulties in the processing of hexagonal or other polygons with inner holes, I think I can try hot stamping. So purchased a car maintenance side of the hydraulic press rack. Nominal 100T, I will not calculate...

My understanding is that screws need to be added to the 17 threaded holes. How do I know how much weight of screws to use in the hole? I think the difficulty of adjusting the balance is that there are only 17 position points and you need to use different weights of screws. Therefore, it is...
