Bearing characteristics |
1. roller and raceway contact or line contact line repair, radial load capacity, suitable for heavy load and shock load. [2] 2 the friction coefficient is small, suitable for high-speed, the speed limit is close to the deep groove ball bearing. 3.N type and NU type axial moving, can adapt to the changes due to thermal expansion and installation error of the shaft and the casing relative position, can be used for supporting the freedom to use. 4.The processing requirements of the shaft or the seat hole 4 higher, bearing outer ring axis relative deviation after installation to strict control, so as to avoid the contact stress concentration. 5.inner or outer ring can be separated, convenient installation and disassembly. |
Use of bearings |
1.Large and medium-sized motor vehicles 2.locomotives, machine tool spindle 3.internal combustion engine 4.Generator 5.gas turbine 6.gear box 7.rolling mill 8.the vibration and hoisting |
