Description Deep groove ball bearings are most representative of the rolling bearing. Widely used in high speed or high speed operation, and very durable, without regular maintenance. This kind of bearing friction coefficient is small, extreme high speed, simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse, used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, the machinery industry, the most widely used class of bearings. Deep Groove Bearings can be used in many areas. Rear wheels, transmissions,electrical devices in automobile industry General motors,household electric appliances in the electric industry Industry of machinery manufacturing of agriculture machines,construction machines,handling&loading machines,textile machines,engineering machines,etc. Industry of precision instuments,machine tools,pumps,internal-combustion engines,etc. Roller skates,yoyo etc. Bearing No. Bore d Outer D Width B Chamfer R Weight kg 6700 10 15 4 0.1 0.002 6701 12 18 4 0.2 0.004 6702 15 21 4 0.2 0.004 6703 17 23 4 0.2 0.004 6704 20 27 4 0.2 0.006 6705 25 32 4 0.2 0.007 6706 30 37 4 0.2 0.009 6707 35 44 5 0.0 0.015 6708 40 50 6 0.3 0.023 6709 45 55 6 0.3 0.025 6710 50 62 6 0.3 0.034
