1. Distinguish from the width of the brake pad, the du of bai13 tons is not as wide as the brake pad of 16 tons;

2. On the surface, 16 tons of wheels are obviously larger than 13 tons of wheels;

3. From the bearing, the shaft head bearing of 16 tons has a large inner gear and a small outer gear, and the bearing of 13 tons has the same size inside and outside.

4. Judging from the toad's head, the 13 tons are the same thickness from inside to outside, while the 16 tons are thicker from inside.

    In the field of industrial equipment, shaft head also refers to the two ends of the shaft. The shaft is a mechanical part supporting rotating parts and rotating together with them to transfer movement, torque or bending moment. Generally, it is a metal circular rod, each section can have different diameters. The two ends of the shaft are often called the shaft head. The function of the shaft head is usually to install the bearing and play the role of running the equipment on the bearing shaft. In the process of shaft movement, shaft head wear, deformation is the most common equipment. Normally, shaft head wear USES is surfacing welding to solve, but influenced by temperature, the deformation of shaft would happen, usually adopt polymer composites technology abroad solve online shaft head wear, by the hardness of material itself and stick relay buffer for bearing the impact on the shaft head, greatly reduces the abrasion of spindle head.
