1-Pack U Type Swivel Pulley 304 Stainless Steel Duplex Bearing Super-Silent Detachable 360 Degree Rotation Heavy Duty Traction Wheel

Purchased to use on a dog run. Runs smoothly on ball bearings. Sturdy construction. Can be disassembled to put on a previously installed line.

I used this on an outdoor zip line for my big dog's outdoor exercise/playtime. He has typically worn grooves through the cheaper ones available locally and they maybe last a few weeks (big dog). This has held up for months now. Definitely worth the cost. Very heavy and durable.

Realized while doing the project that I should have designed 2 pulleys into the plan. Ordered a second that night and had it in 2 days!Plenty sturdy for what I needed it for. I am actually using it upside down, where the wheel is riding on a 1/4 inch steel cable, and cargo is suspended underneath. First test was 250 lbs weight. Pulled along as smooth as silk. Going to add a second pulley to stable the trolley, then load it up and cross/recross 100' creek to get 1000' lbs of material to the other side.

Good quality for the cost. Made in China. Don't know about the longevity yet.

Replaced my DIY pulley system for working out. I bought 3 and these are solid and super quiet!Stoked on this purchase and finally finding a proper pulley. Easy to take apart as well to allow for easy on and off of a line. Pictured is 3/16 coated line from Home Depot. Haven’t put weights on but compared to a Home Depot pulley it’s night and day. BUY BUY BUY no doubt!
