rotary joint component identification

[ValveFloyd]

Good evening,
I'm a mechanical engineering student, and I'm realizing a technology project that involves the comoplete manufacturing studio of a set. I chose as a product to realize a rotating joint of the johnson - fluiten (model r - dual flow), but I have a doubt about the function of a component (see attachment). My interpretation is that it is a spacer for the bearings, and at the same time it serves to separate the inside of the body into two stable chambers, but in this case I cannot understand what material can be done, to ensure isolation and not cause wear.
thanks in advance

p.s.
I also attach the catalogue if the image is not sufficiently complete.

good evening, I think the particular indicated performs a double function: space between the bearings and grease deviator introduced in the two greasers. to be sure to distribute the fat between the two bearings have put two greasers instead of just one, especially because the left bearing, larger, performs the function of bracing of the loads explicated from the mechanical seal, while the second is only a driving bearing. always to ensure maximum fattening the bigger bearing does not have the excess weight and fat pumped at pressure from the calibrated flangetta, while the second bearing has the paragrass that retains the right amount of fat. this spacer has a minimum of play on the outside for rotation compared to the home and for holding the fat. therefore do not need special materials, can therefore be identified as a common spacer.

I agree, too. does not serve to separate joint fluids but to properly grease the two rooms. on the diameter will necessarily be air....tenths of millimeter.

Thank you very much, very kind. I was deceived by the lack of space between the space and the body, thinking so erroneously that they should be in contact with each other. The only thing that I don't understand is the fat speech that draws from the flangetta. Why should the absence of paragrass improve lubrication? and therefore you have fat coming out of the body and spreading into the environment?

happens more than anything at first filling. the fat is introduced with the pump until it draws just from the flangetta, so you are sure to have filled the room. It is also functional for subsequent periodic maintenance in which to peel purging old fat. when there is a paragreasing, it is not possible to adopt this procedure because the ring is made to retain the fat, then it puts a relief valve that signals the spurge.

Now it's all clear. thanks a lot of information and kindness
