PowerRing™ Shaft-Hub Locks provide a keyless, extreme high strength connection between components and round shafts. They feature a smooth, non-marring bore which contracts securely onto a shaft while expanding the OD tightly into the I.D. of a hub. Fully adjustable, they are balanced to minimize vibration at high speeds, and prevent backlash damage caused by heavy loads.

They are easy to install by tightening the locking bolts around the device’s face. When these bolts are tightened, multiple internal taper rings produce the frictional forces necessary to join the shaft and hub allowing the transmission of high torque and axial loads.

Simplifying the timing of matched components, PowerRing™ Keyless Shaft-Hub Locks are ideal for mounting gears, sprockets, pulleys and related devices.

Unsafe and absolutely garbage
Color: Yellow Frisbee, Size: Large
If I could give this zero stars, I would. My dog had it for approximately two minutes of playtime, I didn’t even get to throw it, and it already had holes in it. He wasn’t chewing it or playing aggressively. He simply had it folded in half in his mouth and it tore. This toy is not safe for dogs.

Perfect ball for my Chihuahua
Color: Multi Meteor Ball, Size: Small
My dog is a Chihuahua. The small size is perfect for her. She loves chewing on the ball and loves the crackling noise from the material inside. I love that it is strong enough, she cannot tear it apart or is she able to remove the material inside. Perfect for her.

Best toy for our dogs!
Color: Yellow Frisbee, Size: Large
These are great for our labs. They love to fetch and play in the back yard. Loved how sturdy these have been the last few days. The material is tough enough to withstand our boys.

Bouncy, not hard, and good value.
Style: Fetch Balls (Pack of 10), Size: 2.5 inch
Great balls for the ball launcher and not rockhard like some of the solid rubber balls. These have great bounce, and because of the two holes, they make a fun whistling noise as they fly through the air. My dogs love them and they are a good value. By the way, if you throw them too hard, they will go through chain-link and no climb fence because they squish a bit!

Excellent dog balls — safe design and very durable
Style: Fetch Balls (Pack of 3), Size: 2.5 inch
These fetch balls from Amazon Basics are fantastic, and my dog absolutely loves them. One of the biggest reasons I prefer these over other brands is the hole that runs through the center of the ball. This is a very important safety feature: if a dog were to accidentally get the ball stuck in the back of the throat, the hole allows air to pass through. That small detail could literally make a life-saving difference. Aside from the safety benefit, they bounce well, are easy to clean, and hold up to a lot of playtime. They’re firm but not rock-hard, and my dog goes crazy for them. Great value, great quality, and a thoughtful design. Highly recommended for dog owners who want a safer alternative to standard solid rubber balls.
