WD EMQ ball bearings with high speed limit, low friction torque and low noise, which can not be dismantled can bear both axial and radial loading with a high rotation speed. The closed bearing help the bearing save maintenance and make the structure easy.

EMQ ball bearings are single row angular contact ball bearings comprising solid inner and outer rings and ball and cage assemblies with solid window cages. They cannot be dismantled. The bearings are available in both open and sealed versions.

EMQ Ball Bearings have restricted tolerances. They are particularly suitable for where requires very high guidance accuracy and speed capacity, especially for slewing part of the main spindle of machine tool. To make the bearing work longer hours with heavier load, WD introduces advanced Korean heat treatment production line and a complete set of German rings and steel balls grinding equipment.

WD EMQ Ball Bearings also apply imported lubricant to effectively reduce the noise and friction torque. Therefore, the cage can keep stable and give out less heat while it is in high speed rotation. Meanwhile, the excellent high speed performance is guaranteed.
