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.

Sturdy bouncy fun!
Color: D) 4-Pack 3" Balls (Yellow), Color: D) 4-Pack 3" Balls (Yellow)
Great product. My big 70lb Sheppard puppy loves it, hasn’t stopped playing with it since it arrived. She throws it about and chases it, had a good chew on it and even put it in her favorite toys bin. Sturdy, firm and very bouncy. And there are 3 more in the bag for an awesome price. Bright color will make it easy to find and holes thru it will prevent choking and I can string it on a line for training play.

Dogs love these
Color: C) 2-Pack 2.5" Balls (Yellow)
Great quality balls for tough chewers. I love them, but wish the orange ones were available more...I've been checking cuz they are easier to find in the yard than the green that blends in. Our dogs love them and I like the weight for throwing.

Great quality and folding it in half is a plus. Fits under a seat in car/truck.
Purchased another, as we need one in each car. This is a great ball thrower, especially as it folds in a half. Makes it easy to store under a car/truck seat. Haven’t had any problem with it, great quality!

Fantastic throwing aid!
Very well made, great quality and doesn't feel cheap at all. It's thick, not flimsy or fragile so you can really swing it to launch a ball. Saves my body that I don't have to bend over to pick up the ball anymore, and saves my shoulder that I don't have to hurl the ball anymore. Another bonus is you don't have to touch a slobbered, soggy ball, or a ball covered in dirt.
The foldable design is fantastic because I walk everywhere with my dog and don't want to carry around a long stick that's awkward to hold. This folds down small enough that I can securely put it in the back pocket of my jeans without worrying about it falling out. The thing I love most about it is there's a elastic loop at the end so when you fold it you can latch it securely. This small detail is outstanding because I can also hang it on the strap of my sling bag and with the loop secured it will not slip off the strap.
This product is so well made and thought out overall.

Excellent toy for play
My dog would play all day if I threw the ball to him. He loves this even though he's 12. The scooped end allows you to pick up the ball without touching it. After a few runs it's covered in dog slobber. So that's a major plus for me! Also, some health issues affect my walking and bending at times. This helps with the bending. This is a great game to play with your favorite friend!
