Re: [PSUBS-MAILIST] Lubrication



Hi Hugh,
 
These are not rotating shafts. They are rotating bel cranks which actuate drop weight latches, front and rear thruster orientation and soft ballast valves. Most only turn a 40 - 160 degrees.
 
Thank you for any input.
 
Best Regards,
 
Jim K

Hi Jim,

I would be very careful about steel to steel.  What is the application? What speed are the shafts doing?

If you do go steel on steel then you need to have different hardness and very good grease lubrication. Slow rotation is not so bad but if you can use bronze, Aluminium, white-metal or plastic sleeves then go for it. Stainless on bronze no problem, Chs, Hugh

Hi All,

 

I've not seen this before and am hoping for some expereinced people to help.

 

I am doing final assembly of some rotating shafts. Some are carbon steel inside of carbon steel and some are Stainless shaft inside of bronze bushings.

 

I am not sure if never- seize or a good quality urea grease are better or possibly something that I have not thought of!

 

Thanks in advance,

 

Jim K
