Thin-walled cross roller bearingsCRA series thin-walled cross roller bearings (outer ring split type) are small, lightweight cross roller bearings made of thin outer ring and inner ring. They are small and can withstand heavier loads. The mounting part of the bearing can be lightened.The size of the inner and outer rings of CRB series thin-walled cross roller bearings (outer ring split type) is miniaturized to the utmost extent. Its structure is that the outer ring is divided into two parts, and the inner ring is an integral structure, which is most suitable for the inner ring. Where the rotation accuracy is high.The structure of the CRE series thin-walled cross roller bearings (split inner ring) is that the inner ring is divided into two parts, and the outer ring is an integrated structure, which is most suitable for places that require high rotation accuracy of the outer ring.Thin-walled ring bearings are highly accurate, very quiet and have strong load-bearing capacity. These ball bearings have three designs, and are extremely small and mostly square in cross section. In these series, even with larger shaft diameters and bearing holes, the cross-section remains the same. These bearings are therefore called equal sections. It is this feature that distinguishes thin-walled ring bearings in the standard ISO series from traditional bearings. Therefore, it is possible to choose a larger cross section and use a bearing with a higher load carrying capacity without changing the shaft diameter. Thin-walled ring bearings can be designed to be extremely light and require little space.http://www.zysbearing.com/precision-bearings/thin-section-bearings.html View Details

Considerations for tunnel machine bearings
Once the construction of the tunnel machine bearing, there is no turning back.

The tunnel machine is not equipped with reverse gear, so the machine must be able to complete its work without any obvious mechanical failure on the route. If problems occur, entering the machine for maintenance can be a complicated, expensive and time-consuming project, especially with the main slewing bearing installed in the gearbox of the TBM. The main slewing bearing is the core of the machine. If it fails, it cannot be easily replaced, which may result in months of delay and cost overruns, which may easily increase to millions of dollars. View Details
