Hercules Spherical Bearing (HSB)
The HERCULES Structural Spherical Bridge Bearings are designed according to BS5400, EN1337 or AASHTO as per project specifications. The HERCULES Spherical Bearings typically consist of concave & convex interfaces which accommodate large rotation with very little resistance to the application of moment. The spherical interface shall consist of stainless steel & high compressive & low friction PTFE or special modified polymers. Spherical bearings can be incorporated with top sliding plates & guides to accommodate horizontal movement in one or all direction. Therefore, the spherical bearings can further be categorized as Fixed, Guided & Free Sliding.
