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.

Smaller than expected.
Size: Medium, Color: Black, Size: Medium, Color: Black
Nice quality to make my son his own design sweatshirts.
My son is 7, and all sweaters I have bought from Walmart and Target are size medium and fit him great. This size medium was small. So I would definitely size up.

Gathers up at waist :P
Size: Medium, Color: White
Pretty good sweatshirt BUT it pulled up the fabric in an uncomfortable way; Instead of the waistband being at the hips area(?) , it kept going ip to my waist no matter how much i pulled it down.

Great Value & Quality Hoodie
Size: XX-Large, Color: Black
My son absolutely loves these hoodies! I’ve already ordered them in four colors. He’s just shy of 11 year old, very tall and skinny, and the XXL fits him perfectly with plenty of room to grow over the next year. The fabric is soft, cozy, and comfortable, and the hoodie holds up well to everyday wear. Great value for the money—definitely a go-to in our wardrobe! I love the unique color options.

Good quality
Size: Large, Color: Golden Yellow
This was true to size and is a nice quality sweatshirt. It is soft but not buttery soft. It was a good value since my child wanted it for part of a Halloween costume. He has worn it again which makes the purchase even better
