Spherical Steel Bearing in China

Ⅰ. Basic Technical Features
1,Corner: longitudinal0.04 rad, crosswise 0.02 rad
2,Temperature range: —25~+60°C
3,Every Reserved clearance of contact surface in the sliding direction of fixed bearing and one-way movable bearing is  3mm, the horizontal force is 15% of the vertical load.
4,Under the vertical load, the vertical compression deformation of the bearing is not more than 1% of the total height.
5,Both the coefficient of frictions of the plane friction pair and the spherical friction pair are not more than 0.05.
6,Bearing materials used in line with GB T17955-2000 ball bearings technical conditions standard. 
7,Dust cover to prevent dust buildup in the exposed friction surface.
8,The exposed steel bearing surface coating expectancy of not less than 10 years.
9,At bearing installation the beam end and piers are embedded steel plate and anchor column, anchor bolt dimensions and anchor column size are shown in Table.
