Description: 

Spherical bearing is formed by top steel plate, stainless steel slide, PTFE slide, convex plate, curved PTFE and concave plate.
It is designed for high vertical, horizontal and lateral loads and where large rotational structural displacements need to be accommodated.The sliding of convex plate and concave plate can accommodate the structural rotations of the beam end. The stainless steel slide and PTFE slide can further reduce friction coefficient, thus displacement of expansion and contraction can be accommodated.

Features：

•  Large vertical loading capacity. 

•  Allows for large horizontal displacement.

•  Better adapting to large rotations. 

•  Min. sliding friction coefficient.

•  More suitable for the low temperature regions.

Types: 

•  Fixed bearing - only allows for rotations, any longitudinal or traversal movement is restrained.

•  Guided sliding bearing - with edge steel guide accommodates unidirectional movements

•  Free sliding bearing - can slid in all directions.

Design and fabrication standard:

•  Pot bearing for highway bridges GB/T 17955-2009

•  In reference with EN1337-7

•  In reference with BS 5400, Part 9, ”Bridge Bearing”

Certificate:

•  CE Certificate of Constancy of Performance - Spherical and cylindrical PTFE bearing under the standard of EN 1337-7: 2004

•  ISO 9001 Certificate - Quality Management System
