4’’ TPR Heavy Duty Swivel Caster Wheels Lockable Ball Bearing 1200lbs (Set of 4) - Silver Gray

Excellent quality. They roll very nicely

I installed these on cart to move equipment/parts. They work great.

solid, durable

I put these on my garage work bench and they work great, I can move my bench around the garage or out to the driveway. Casters work easily and the brakes are easy to put on or off.

These worked great for the movable workbench my husband built. They are very sturdy and the locks and swivels work great.

Used on heavy duty steel workbench - made very well

Installed on a storage cabinet in my shop to make it mobile. These are replacements for the casters that came with the cabinet.

This product exceeded expectations!

Perfect height, and the wheel bearings are commercial quality. Very smooth roll.

This is a follow-up to my prior review. Ive ordered 4 sets of these casters. During use recently, I had one break, partly due to my user error. The caster got stuck on a piece of wood, wouldnt turn, and because it was on a heavy miter saw table, the interior component plastic stressed and broke when I tried to roll and move the table in my garage. So, I disassembled the broken caster and took some photos to show the internal guts of the caster. When the caster failed, I jacked up my table, removed the caster (reinstalled another matching caster in its place). The caster is a hard plastic wheel hub that encases a steel ball bearing. So, it is some metal inside. For the price of these casters, Im relatively still happy with the product. I was able to trim out the broken plastic housing, re-insert the steel bearings, glue in the bearing and re-attach the dust cover that had been bent/damaged. These casters have limitations, and Im clearly using them beyond what they were intended for - so one failed out of the 16 Ive purchased. Note I gave it 4-stars - because for the price, they are fairly good units. But they are not indestructible. But, when one broke, I was able to apply a little ingenuity and was able to put it back into service on a lighter duty table. It does roll still, and now that I know how theyre made, Ill be a little more careful. Hope the pics help understand the product. Id still buy them again - but know they wont hold 1,000 lbs each. Theyre rated for about 250 lbs each - and if stressed hard, that can even exceed their capability.
