Product Description

Product Introduction
Description: 
Spherical bearing is a special bearing product composed of upper bearing plate, lower bearing plate, spherical plate, polytetrafluoroethylene sliding plate (F4, spherical PTFE plate), and rubber retaining ring. It is named after changing the rubber plate in the basin type support to a spherical PTFE plate. As the middle steel plate and bottom basin of the QZ spherical support are also correspondingly changed to spherical, the friction coefficient is reduced. Its displacement is achieved by sliding between the upper support plate and the flat PTFE plate. Setting guide grooves or guide rings on the upper support plate to constrain the unidirectional or multi-directional displacement of the support can be made into spherical unidirectional movable supports and fixed supports. The sliding between the spherical plate and the spherical PTFE plate is used to meet the needs of the support angle.
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
