[0002] Machine tool steering gear generally refers to a device used to control the direction of rotation and movement of components such as machine tool worktables or tool holders. These devices can adopt different designs and technologies to meet the precision, speed and flexibility requirements of machine tool processing. The angular contact bearing inside the machine tool steering gear is a common type of rolling bearing. The contact angle between the inner and outer rings is about 15 to 40 degrees, so it is called an angular contact bearing. This type of bearing can withstand radial and axial loads at the same time, and can maintain high accuracy at high speeds. Nylon cage refers to a cage used in bearings, which plays an important role in bearings.
