self-aligning ball bearing has two rows of balls and a common concave sphered raceway in the outer ring. self-aligning ball bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. self-aligning ball bearing is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds. self-aligning ball bearing is Widely used in machinery of mining, power, and textile etc GPZ Bearing No. | Boundary dimensions | Basic load ratings(kN) | Limiting speed | Mass | mm | Dynamic | Static | rpm | kg | d | D | B | rsmin | Cr | Cor | Grease | Oil | ≈ | 1300 | 10 | 35 | 11 | 0.6 | 7.25 | 1.62 | 18,000 | 21,000 | 0.058 | 1301 | 12 | 37 | 12 | 1 | 9.45 | 2.16 | 16,000 | 18,000 | 0.066 | 1302 | 15 | 42 | 13 | 1 | 9.55 | 2.3 | 13,000 | 16,000 | 0.092 | 1303 | 17 | 47 | 14 | 1 | 12.5 | 3.2 | 12,000 | 14,000 | 0.128 | 1304 | 20 | 52 | 15 | 1.1 | 12.4 | 3.35 | 11,000 | 13,000 | 0.16 | 1304K | 20 | 52 | 15 | 1.1 | 12.4 | 3.35 | 11,000 | 13,000 | 0.158 | 1305 | 25 | 62 | 17 | 1.1 | 18 | 5 | 9,100 | 11,000 | 0.255 | 1305K | 25 | 62 | 17 | 1.1 | 18 | 5 | 9,100 | 11,000 | 0.251 | 1306 | 30 | 72 | 19 | 1.1 | 21.3 | 6.3 | 7,700 | 9,100 | 0.383 | 1306K | 30 | 72 | 19 | 1.1 | 21.3 | 6.3 | 7,700 | 9,100 | 0.377 | 1307 | 35 | 80 | 21 | 1.5 | 25.1 | 7.85 | 6,800 | 8,000 | 0.5 | 1307K | 35 | 80 | 21 | 1.5 | 25.1 | 7.85 | 6,800 | 8,000 | 0.492 | 1308 | 40 | 90 | 23 | 1.5 | 29.6 | 9.7 | 6,000 | 7,000 | 0.709 | 1308K | 40 | 90 | 23 | 1.5 | 29.6 | 9.7 | 6,000 | 7,000 | 0.698 | 1309 | 45 | 100 | 25 | 1.5 | 38 | 12.7 | 5,400 | 6,300 | 0.953 | 1309K | 45 | 100 | 25 | 1.5 | 38 | 12.7 | 5,400 | 6,300 | 0.938 | 1310 | 50 | 110 | 27 | 2 | 43.5 | 14.1 | 4,900 | 5,800 | 1.2 | 1310K | 50 | 110 | 27 | 2 | 43.5 | 14.1 | 4,900 | 5,800 | 1.18 | 1311 | 55 | 120 | 29 | 2 | 51.5 | 17.9 | 4,500 | 5,200 | 1.58 | 1311K | 55 | 120 | 29 | 2 | 51.5 | 17.9 | 4,500 | 5,200 | 1.56 | 1312 | 60 | 130 | 31 | 2.1 | 57 | 20.8 | 4,100 | 4,800 | 1.96 | 1312K | 60 | 130 | 31 | 2.1 | 57 | 20.8 | 4,100 | 4,800 | 1.93 | 1313 | 65 | 140 | 33 | 2.1 | 62 | 22.9 | 3,800 | 4,500 | 2.42 | 1313K | 65 | 140 | 33 | 2.1 | 62 | 22.9 | 3,800 | 4,500 | 2.38 | 1314 | 70 | 150 | 35 | 2.1 | 74.5 | 27.7 | 3,500 | 4,200 | 2.99 | 1315 | 75 | 160 | 37 | 2.1 | 79.5 | 30 | 3,300 | 3,900 | 3.55 | 1315K | 75 | 160 | 37 | 2.1 | 79.5 | 30 | 3,300 | 3,900 | 3.5 | 1316 | 80 | 170 | 39 | 2.1 | 88.5 | 33 | 3,100 | 3,600 | 4.17 | 1316K | 80 | 170 | 39 | 2.1 | 88.5 | 33 | 3,100 | 3,600 | 4.11 | 1317 | 85 | 180 | 41 | 3 | 97.5 | 38 | 2,900 | 3,400 | 4.96 | 1317K | 85 | 180 | 41 | 3 | 97.5 | 38 | 2,900 | 3,400 | 4.89 | 1318 | 90 | 190 | 43 | 3 | 116 | 44.5 | 2,700 | 3,200 | 5.78 | 1318K | 90 | 190 | 43 | 3 | 116 | 44.5 | 2,700 | 3,200 | 5.69 | 1319 | 95 | 200 | 45 | 3 | 132 | 51 | 2,600 | 3,000 | 6.69 | 1319K | 95 | 200 | 45 | 3 | 132 | 51 | 2,600 | 3,000 | 6.59 | 1320 | 100 | 215 | 47 | 3 | 143 | 57.5 | 2,400 | 2,900 | 8.3 | 1320K | 100 | 215 | 47 | 3 | 143 | 57.5 | 2,400 | 2,900 | 8.19 | 1321 | 105 | 225 | 49 | 3 | 156 | 64.5 | 2,300 | 2,700 | 10 | 1322 | 110 | 240 | 50 | 3 | 164 | 71.5 | 2,200 | 2,600 | 11.8 | 1322K | 110 | 240 | 50 | 3 | 164 | 71.5 | 2,200 | 2,600 | 11.7 |
