Product Description

Product Description

Spherical bridge bearing, also called spherical bearing, spherical bearing pad, is designed to ensure vertical and horizontal forces transferring under control which is a connection devices between superstructures and substructures. It consists of steel plate enclosed with edge sliding guide and stainless steel panel for sliding controlling, under the stainless steel panel is a PTFE sheet, which is recessed into the steel to a depth and contains a special lubricant to ensure permanent lubrication of the sliding surfaces. Then there is a stainless steel panel with a convex bottom face to facilitate rotations. The bottom component is concave steel plate that covered with a recessed PTFE sheet to transfer whether horizontal or vertical forces safely.

Classification

The spherical bridge bearings are classified into three types according to different sliding direction.

• Fixed type. Provide rotations capacity from any direction only.
• Guided type (Uni-directional sliding). Rotation plus movement in one direction.
• Free sliding (multi-directional sliding). Rotation plus movement in all directions.
• 

Material	Steel and PTFE sliding plate.
Working temperature range	Normal type: -25 °C to +60 °C. Cold resistant type: -40 °C to +60 °C.
Friction coefficient	(In condition of PTFE layer with silicon grease lubrication and stresses about 30 MPa) Normal temperature: 0.03. Low temperature: 0.05.
Bearing horizontal force	Guided type: Horizontal force is 10% vertical bearing capacity. Fixed type: horizontal force is 10% vertical bearing capacity.
Vertical bearing capacity	1000, 1500, 2000, 2500, 3000, 4000, 5000, 6000, 8000, 9000, 10000, 12500, 15000, 17500, 2000 kN.
Displacement	In longitudinal direction 1000-2500 kN, 50/100 mm. 3000-20000 kN, 50/100/150 mm. In transverse direction: ± 40 mm.
Popular specifications	Fixed type spherical bridge bearing. Guided type spherical bridge bearing. Free sliding type spherical bridge bearing.

Application

• Spherical bridge bearings are designed for bridges or structures where very high vertical, horizontal and lateral loads are needed.
• It is can also be used in places where large rotational structural displacement are needed to be accommodated.
• Spherical bridge bearing can be used in different complex bridges, such as curved bridges, skew bridges, right bridges.

Feature

• Available in any directions movements.
• For the PTFE sheet, there are minimum sliding friction coefficient.
• PTFE sheet with lubricant to reduce sliding friction.
• Accommodate high rotations and any directional movements.
• Suitable for low temperature regions.
• The effect on concrete reaction is homogeneous.
• Strong enough for long time service.
• Complying with BS EN-1337, KS4424, AASHO, ISO or other custom standards.
