Kafly 8" X 2" Heavy Duty Polyurethane Caster Wheel Steel Hub Roller Bearing & 1/2" Bushing 1400 Lb.

Replaced the wheels on our U-boats in our store, and the difference is extremely noticeable. The second an employee starts to push them they notice the anticipated normal heave needed, sends the U-boats in easy motion.These do not have ball bearings, but roller bearings. Far stronger, evenly distributed weight on the inner wheel.We use these also in our freezer at -20°F. Installing these with lithium grease they work like a charm even in there.We all are very pleased with the results. I would recommend them.

Great price & they work perfectly

Absolutely Smooth and Well Built!

Used for airplane hanger doors

Exactly what husband was wanting to replace cheap wheels that came on dolly.
