Granor Structural Bearings
Proprietary Structural Bearing solutions – Pot Type
Primarily of metal construction, the critical element of Granor® Pot Type Structural Bearings is the elastomeric pad, which is designed to structurally accommodate movement. Granor® manufactures a range of the widely used Pot Type Structural Bearings, with each design customised to specific application requirements.
Granor® Pot Type Structural Bearings feature a circular elastomeric pad encapsulated inside a metal “pot” having a close fitting lid, which acts as a “piston”. Sealing rings, typically recessed into the circumference of the elastomeric pad, are designed to resist extrusion of the elastomeric pad when under load.
In this mode, the elastomeric pad acts more like a fluid than a solid and accepts high stress – typically 50 MPa Ultimate Limit State – while permitting multidirectional rotation of the supported structure.
Granor® manufactures according to customers’ required international codes. In Australia, designs comply with AS.5100.4. Granor® can also compliance test up to 19,000 kN vertical with a simultaneous horizontal load of 2,500 kN to confirm design integrity.
• POTSTAY® - Fixed type
• POTFLOAT® - Free float, multi directional, slide movement
• POTGLIDE® - Guided type with slide movement restricted to one direction
Advanced designs for many of these Bearings are available to suit sophisticated applications, such as designs permitting incremental launching of the superstructure, or the incorporation of an Anti Up Lift feature.
