 Pot Bearings

 Fixed or Sliding

 Designed According to AASHTO  Allow for rotation of up to.040 radians

 Free Sliding – Moves in all directions, no horizontal force

 Fixed – Immovable, accommodates horizontal force

 Center Guided Sliding – Accommodates horizontal forces that are perpendicular

 Lower Profile, Same Movement & Load Capacity  Polyurethane stronger than Elastomeric Seal

 Physical Property Requirements

 Access Live Data from the Expansion Joint via the Internet.  Data is sent with a wireless connection. Bearings Internet

 How Does it Work? sms/mms
