Die PSS Wellendichtung Typ A ist eine mechanische Gleitringdichtung. Die Dichtfläche entsteht zwischen den ebenen Flächen des rotierenden Edelstahlrotors und dem stationären Kohleflansch.Der stationäre Kohleflansch wird mit Schlauchklemmen an der Vorderseite des Balges und das hintere Ende des Balges über das Sternrohr befestigt und wird mit Schlauchklemmen gesichert. Der Edelstahlrotor ist auf der Welle vor dem Kohleflansch montiert. Der Edelstahlrotor wird verwendet, um den Balg zu komprimieren, bevor der Rotor mit Stellschrauben an der Welle befestigt wird. Diese Kompression (Vorspannung) sorgt für einen konstanten Kontakt zwischen den beiden flachen Seiten des Edelstahlrotors und des Kohleflansches. Dadurch kann die PSS Wellenabdichtung die variable Vorwärts- und Rückwärtsbewegung - bedingt durch den Propellerschub - ausgleichen. Der Kohlenstoffflansch ist zum Wellendurchmesser überbohrt, so dass er um die Welle herum 'schwimmen' kann und somit die meisten Fehlausrichtungs- und Schwingungsprobleme ausgleicht. Der Rotor aus rostfreiem Stahl ist durch zwei O-Ringe, die in die Bohrung des Kragens eingelassen sind, gegen die Welle abgedichtet. Diese O-Ringe rotieren mit der Welle und dem Edelstahlrotor und unterliegen keinem Verschleiß während des Betriebs.
Temperaturbegrenzungen: 5°F bis 225°F (-15°C bis 107°C)

Kohlenstoff-Graphit: Auf 4 HLB geläppt (0,00000044' Toleranz)

Great mini backpack
Color: Black
I love this backpack purse! It has so many pockets; 2 side pockets great for water bottles, umbrella, or my sunglass case. And I love the safety features. The only reason I gave it 4 stars instead of 5 is that the adjustable straps sometimes slip out. I will need to bring it to the shoe repair shop to have one more fold sewn into the end of the strap to prevent it from continuing to slip out.

Handy backpack!
Color: Green
Love it! Perfect for a plane ride and trips to amusement parks or hikes! Both side pockets will hold a water bottle! Just what I was looking for! The color is pretty too! Much prettier in person!

Tiny but convenient!
Color: White, Color: White
Long review: TLDR; it’s cute, pretty durable, tiny but spacious, and handy!
First, I feel I should mention—it’s very tiny! I didn’t look at the dimensions, so that’s my fault, haha, not taking points off for it lol. It’s not big enough to fit, say an iPad Pro, but maybe a mini! It’s height is probably enough for a small book, and it’s width is definitely enough for a regular sized book. Also the length from back to front of the bag: it’s very thick! So it fits a lot for the size. It fits my about 1.5 inch thick wallet (about 5-6 inches long), my keys, a mini hairbrush, and a bag I use with toiletries like pads/tampons, mini body spray, mini hand cream, a tiny metal wallet with bandaids, hair ties, q-tips, and cotton rounds, and a couple chapsticks. The front pocket is pretty spacious too, as it fits my AirPods with a case and a bunch of keychains and dangly things on it.
The straps are long and adjustable. It looks easy to clean but I haven’t spilled anything or gotten anything on it so it’s a little hard to say. I’ve included a video and pictures for reference!
It came pretty smushed and squashed into a flat little pancake but it only took a little while to go to it’s intended shape. I left it full of stuff to mold it overnight (like if you stuff it gently/loosely with, say, a t-shirt or two overnight, it’ll morph into the right shape)
The puff ball is cute, and it’s staying on pretty well, but the elastic thing holding it on is slowly stretching a little so it doesn’t look like it’s glued on like I liked at first, but it still looks good!
It’s lasted a while now, probably a few months with no issues.
Basically, I like it and it’s handy for going to the mall or store, or if you bring very small stuff to the amusement park. (It won’t fit a water bottle, but it’ll fit smaller stuff)
In the video, I showed me unpacking all the stuff it can fit, and in the first picture is all that stuff. In the second picture I show the size of my 12.9 inch iPad Pro to as comparison, and in the third picture I show how it barely doesn’t fit.
Hope this helps!!
