Precision Deep Groove Ball Bearings
The deep groove ball bearing is a kind of rolling bearing with most representatives, and it has features of small friction coefficient, high limiting speeds, simple structure, low cost, and high manufacturing precision. It has various sizes and structures, and is used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries, and a kind of bearing with most applications in the machinery industry. The bearing can bear mainly the radial load, but also can bear a certain axial load.618Deep groove ball bearingsDimensionsBasic Load RatingDesignationWeightInstallation SizeLimiting SpeedmmkNkgmmr/mindDBrminCrCordaminDamaxramaxGreaseOil.621.2618200..130.7618220...136.941.2618260.94136.5158..138.244.4618281146.5168..149.158.5618301.15156.6183..148.561618321.23166.5193..161.578618341.9176.5208..162.378.5618361.72186.5218..575.193.5618382.531982321...672082421..576.597.8618442.92282621..5108618484...DimensionsBasic Load RatingDesignationWeightInstallation SizeLimiting SpeedmmkNkgmmr/mindDBrminCrCordaminDamaxramaxGreaseOil300380382.................34735672..44935872./50037.25136072./53039.85436372./56041.55736672./60050.96137172.5670800DimensionsBasic Load RatingDesignationWeightInstallation SizeLimiting SpeedmmkNkgmmr/mindDBrminCrCordaminDamaxramaxGreaseOil/63071./67075./71092./////
