Descriptions on LZWB spherical thrust roller bearing :

Thrust spherical roller bearings for axial load mainly axial. Meridional joint load, but after the load should not exceed 55% of the axial load. With the other thrust roller bearings, such bearings lower friction coefficient, high speed, and with self-aligning capability. 29000 roller bearing asymmetric spherical roller, can reduce the stick and the raceway at work relative sliding and roller length. Diameter, roller quantity load capacity, often using oil lubrication, individual low speed can be greased. In the design selection should be preferred.

Thrust Roller Bearings are available with cylindrical or spherical rollers. These bearings sustain only axial loads, but have high axial rigidity and are suitable for heavy loads. They contain convex rollers, have a self-aligning capability and are free of any influence of shaft deflection or mounting error. Standard cages are machined brass, where the E-type offers a pressed cage for high load capacity.

G Shaped Finned Tube

The inlaid spiral finned tube is to pre-process the spiral groove of a certain width and depth on the steel pipe, and then inlay the steel strip on the steel pipe on the lathe. During the winding process, due to a certain pre-tightening force, the finned tube steel strip will be tightly clamped in the spiral groove, thus ensuring a certain contact area between the steel strip and the steel tube. In order to prevent the steel strip from springing back and falling off, both ends of the steel strip should be welded to the steel pipe.

Finned Tubes

In order to facilitate inlaying, there should be a certain side clearance between the steel strip and the spiral groove. If the side clearance is too small and interference is formed, it will be difficult for the mosaic process to proceed smoothly. In addition, the wound steel strip always has a certain springback, as a result, the steel strip and the bottom surface of the spiral groove cannot be well joined. Inlaid fins can be carried out on general-purpose equipment, and the cost is not high, but the process is complicated and the production efficiency is low.
