All the bearings you'll ever need for your simple project are right here, and they're incredibly affordable. **Every bearing uses standard 6mm Airsoft BBs.** Ranging from 20 millimeters to 200 millimeters in outer diameter, with 2 and 5 millimeter increments, these bearings are a mere 7.1 millimeters thick. I'm curious to know what you could possibly do with a 200-millimeter bearing - if you have an amazing project, send us a picture! Each geometry has been optimized to minimize the gap between spheres, ensuring maximum performance. **If the internal diameter of the bearing is not suitable for your needs, you can easily adjust it using the provided .STP file.** Here's a quick reference chart: D-Out | D-In | N.Spheres * 20 | 4 | 6 * 22 | 6 | 7 * 24 | 8 | 8 * 25 | 8 | 8 * 26 | 10 | 9 * 28 | 12 | 10 * 30 | 14 | 11 * 32 | 14 | 12 * 34 | 16 | 13 * 35 | 18 | 14 * 36 | 18 | 14 * 38 | 20 | 15 * 40 | 22 | 16 * 42 | 24 | 17 * 44 | 26 | 18 * 45 | 28 | 19 * 46 | 28 | 19 * 48 | 30 | 20 * 50 | 32 | 21 * 52 | 34 | 22 * 54 | 36 | 23 * 55 | 38 | 24 * 56 | 38 | 24 * 58 | 40 | 25 * 60 | 42 | 26 * 62 | 44 | 27 * 64 | 46 | 28 * 65 | 48 | 29 * 66 | 50 | 30 * 68 | 52 | 31 * 70 | 54 | 32 * 72 | 56 | 33 * 74 | 58 | 34 * 75 | 58 | 34 * 76 | 60 | 35 * 78 | 62 | 36 * 80 | 64 | 37 * 82 | 66 | 38 * 84 | 68 | 39 * 85 | 68 | 39 * 86 | 70 | 40 * 88 | 72 | 41 * 90 | 74 | 42 * 92 | 76 | 43 * 94 | 78 | 44 * 95 | 78 | 44 * 96 | 80 | 45 * 98 | 80 | 46 * 100 | 82 | 47 * 102 | 84 | 48 * 104 | 86 | 49 * 105 | 88 | 50 * 106 | 88 | 50 * 108 | 90 | 51 * 110 | 92 | 52 * 112 | 94 | 53 * 114 | 96 | 54 * 115 | 98 | 55 * 116 | 98 | 55 * 118 | 100 | 56 * 120 | 102 | 57 * 122 | 104 | 58 * 124 | 106 | 59 * 125 | 108 | 60 * 126 | 108 | 60 * 128 | 110 | 61 * 130 | 112 | 62 * 132 | 116 | 64 * 134 | 118 | 65 * 135 | 118 | 65 * 136 | 120 | 66 * 138 | 122 | 67 * 140 | 124 | 68 * 142 | 126 | 69 * 144 | 128 | 70 * 146 | 130 | 71 * 148 | 132 | 72 * 150 | 134 | 73 * 152 | 136 | 74 * 154 | 138 | 75 * 156 | 140 | 76 * 158 | 142 | 77 * 160 | 144 | 78 * 162 | 146 | 79 * 164 | 148 | 80 * 166 | 150 | 81 * 168 | 152 | 82 * 170 | 154 | 83 * 172 | 156 | 84 * 174 | 158 | 85 * 176 | 160 | 86 * 178 | 162 | 87 * 180 | 164 | 88 * 182 | 166 | 89 * 184 | 168 | 90 * 186 | 170 | 91 * 188 | 172 | 92 * 190 | 174 | 93 * 192 | 176 | 94 * 194 | 178 | 95 * 196 | 180 | 96 * 198 | 182 | 98 * 200 | 184 | 99
