Main application areas of QIBR metric cross tapered roller bearings
Vertical grinders
QIBR metric cross tapered roller bearings can provide high-precision positioning due to their design to reduce clearance and deformation. This is essential for the precise rotation of the spindle in the vertical grinder and the accuracy of the grinding process. The rigidity of the bearing can reduce vibration and error during the operation of the grinder, and improve processing accuracy and surface finish.
Large gear hobbing machine
QIBR metric cross tapered roller bearings have high rigidity, which helps to reduce vibration during machine operation and ensure the stability of the gear hobbing machine during processing. It effectively reduces the processing error caused by mechanical vibration and improves the quality and reliability of processing.
Crane center pivot
The center pivot of the crane needs to bear large radial loads and axial loads at the same time. QIBR metric cross tapered roller bearings can effectively support these loads and can handle large overturning moments. In the dynamic operation of the crane, the high load-bearing capacity of the cross tapered roller bearing ensures the stability and reliability of the center pivot.
