Review on 🛹 Sackorange Miniature Bearings Pack: Enhancing Skateboard Performance by Mike Carter

This is my second order. The bearings came in standard plastic tubes (2 tubes of 10). Tubes are handy for storing and organizing until you need them. Twisting feels very smooth - no noticeable grain or grinding. I haven't used them in a higher RPM scenario, so I can't comment on their ability to withstand prolonged heat and stress. They're coated in a thick lube, so don't expect them to twirl wildly in your fingers when fresh out of the box. Applying a small amount of light grease breaks down the grease and it actually spins freely like a pinwheel bearing. if you wanna do that The outer and inner rings are made of solid steel. I pressed them down (and sometimes even coaxed them with a hammer! 🙀), I didn't leave any dents or dents. The inside and outside diameters were pretty accurate for my use. I measured the batch and found that they are all within +/- 0.01mm. * My iGaging IP54 electronic digital caliper was pretty accurate, but YMMV. The depth varied the most. The smallest dimension was 6.99 mm and the largest 7.09 mm. Outer Diameter: 20mm Inner Diameter: 8.1mm Depth: 7mm
