Cylindrical roller bearing type belongs to the separation bearing, install and disassemble very convenient, cylindrical roller bearing can withstand the big radial direction load and suitable for use in high-speed operation situation, raceway and rolling body is in the shape of geometry has high bearing capacity, guard and roller end face of the new structure design, not only can improve the bearing axial bearing capacity, at the same time can improve the roller end face and penal contact area of the lubrication conditions, improve the use of bearing performance.
The internal structure of cylindrical roller bearing by roller are arranged 90 ° vertically cross each other, with intervals between roller holder or isolation, to prevent mutual friction between roller tilt or roller, effectively prevent the rotation torque increases.
Cylindrical roller and race for line contact bearing.Load capacity is big, mainly bear radial load.Roller and ring guard friction small, suitable for high speed rotation.
May according to the ring presence of guard, NU, NJ, NUP, N, NF, such as single row cylindrical roller bearings, double row cylindrical roller bearing and NNU, NN and other.The bearing inner ring and outer ring is separable structure.
Cylindrical roller bearing characteristics
1. The roller and raceway for the line contact or offline contact, radial bearing capacity big, apply to under heavy load and impact load.
2. The friction coefficient is small, suitable for high speed, the limit speed close to the deep groove ball bearings.
3. The N type and NU type axial movement, can adapt to shaft caused by thermal expansion or installation error and shell the change of relative position, can be used for free end bearing.
4. On the shaft or hole of the processing and the demand is higher, bearing outer axis relative deflection after installation to be kept under strict control, so as not to cause contact stress concentration.
5. The inner ring or outer ring separable, easy to install and disassemble.
