Hengshui rolling steel bearing manufacture

Main technical properties of bidirectional rolling seismic spherical hinge steel bearing (grid steel bearing):
1
Can bear vertical load;
2
The two-way rolling anti-seismic spherical hinge steel bearing has the performance of resisting vertical tension, so as to ensure that the upper and lower structures are not disconnected during vertical earthquake;
3
It has the performance of resisting horizontal force to ensure that there is no beam falling during horizontal earthquake;
4
The two-way rolling anti-seismic spherical hinge steel bearing can meet the radial and circumferential displacement requirements;
5
It can meet the requirements of corner in any direction;
6
The two-way rolling anti-seismic spherical hinge steel bearing has good shock absorption performance;
7
The overall performance of the bearing is good;
The rolling steel support is composed of a steel pipe support installed (clamped or welded) on the pipe and a roller shaft, roller or ball disc arranged on the supporting structure to form a movable support for the heating pipeline
It can reduce the displacement of the pipeline when it expands and contracts
Roller shaft and roller type support
When the pipeline is axially displaced, there is rolling friction between the pipe support and the rolling parts, and the friction coefficient is less than 0
1; However, there is still sliding friction during the lateral displacement of the pipeline

The rolling hinge support is composed of a steel pipe support installed (clamped or welded) on the pipe and a roller shaft, roller or ball disc and other components arranged on the supporting structure to form a movable support for heat supply pipeline

Roller shaft and roller type support
When the pipeline is axially displaced, there is rolling friction between the pipe support and the rolling parts, and the friction coefficient is less than 0
1; However, there is still sliding friction during the lateral displacement of the pipeline
For ball disc bearing, the horizontal and isotropic movement of pipeline is rolling friction
It requires necessary maintenance to keep the rolling parts in normal condition
