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

I bought this for my DIY home gym pulley system. A bit pricey since there a lot of smaller and inexpensive pulleys in the marketplace. But I don’t regret buying these for a minute because they are strong, durable and smooth. No squeaking, no tracking issues and up to the task when I load up weights doing back exercises. Well worth the extra expense.

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

Exactly what I expected and got a great basic pully with very smooth clean roll and the wheel fits tightly and solidly on the frame. Good swivel support ring as well. So far very satisfied with quality of the pully.

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

Great quality product. Better than I was finding at the hardware store. Needed one that had a bearing with it as this one does.

The pulleys function, but not how they are supposed to. The bearings fall out the sides, and when the nut is tightened so the inner washers clamp on the inner race of the bearings, the pulley does not spin. It still functions, but it's about as effective as a solid metal wheel on a steel bolt. As a machinist, I would suggest the company tighten the tolerance on the bearing counterbore by about .0005" to hold the bearings properly, and make sure their washers are the correct size to only clamp on the inner race of the bearings when the bolt is tightened. To other consumers, you may need to replace the bearings and inner washers. Would not suggest putting anything close to the full load this pulley should be able to handle on it.

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.

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.

Strong and heavy pulley.
