Bearing manufacturers Products Description Self-aligning ball bearings Self-aligning ball bearings 2215ETN9 have two rows of balls and a common sphered raceway in the outer ring. The bearings are insensitive to angular misalignment of the shaft relative to the housing. Self-aligning ball bearings 2215ETN9 generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds. Self-aligning ball bearings are available in several designs, including: 1) Basic design bearings (pic. 1) 2) Bearings with an extended inner ring (pic. 2) 3) Sealed bearings (pic. 3) Bearing No.Boundary dimensionsBasic Load Rating KNSpeed Rating r/minWeight kg mm 10000 (TN1,M)10000K (TN1,M) Tapered BoredDBCrCorGrease LubricationOil Lubrication Cylindrical 12031203K1740127.92.0216000200000.076 22032203K17401692.4516000200000.09 13031303K17471412.53.1814000170000.14 23032303K17471914.53.5813000160000.17 12041204K2047149.952.6514000170000.12 22042204K20471812.53.2814000170000.15 13041304K20521512.53.3812000150000.17 23042304K20522117.84.7511000140000.22 12051205K255215123.312000140000.14 22052205K25521812.53.412000140000.19 13051305K25621717.85.0510000130000.26 23052305K25622424.56.489500120000.35 12061206K30621615.84.710000120000.23 22062206K30622015.24.610000120000.26 13061306K30721921.56.288500110000.398 23062306K30722731.58.688000100000.5 12071207K35721715.85.088500100000.32 22072207K35722321.86.658500100000.44 13071307K358021257.95750095000.54 23072307K35803139.211710090000.68 12081208K408018196.958500100000.42 22082208K40802331.910750090000.51 13081308K40902333.811.2670080000.72 23082308K4090335416630075000.93 12091209K45851922.97.87750090000.47 22092209K45852332.510.6700085000.55 13091309K45100253913.4630075000.96 23092309K451003663.719.3560067001.25 12101210K50902026.59.15700085000.53 22102210K50902333.811.2630075000.6 13101310K501102743.614560067001.2 23102310K501104063.720530063001.65Bearing manufacturers website:http://www.zwzmachinery.com/bearing/
