Ordered 2 sets to replace aging wheels on several woodworking machines. I installed the first set on an old Steel Stand Craftsman puzzle. The wheels are easy to install and I particularly appreciate the full lockout that locks both spin and spin, which also makes installation easier. I added a couple of washers to each roller between the top of the roller and the frame to eliminate any slack that could cause the bars to fold or twist. It's a fairly light application for very heavy reels so so far they've worked really well, when fixed the table doesn't move at all which is crucial for the safe operation of the equipment. My second set will be running on a much heavier jointer/planer so I'll update if anything comes up, but for now it's a solid 5 star product that I'll probably be buying more of in the near future.
