Design

TETRON® CD are made up of an elastomer pad confined in a steel cylinder or pot, which is fitted on the top with a circular steel plate (piston).

The elastomer behaves like a viscous fluid under high pressure flowing to allow rotation and tilting movements of the piston about any horizontal axis.
For guided or fixed bearings, external lateral forces are transmitted by suitable restraints or guides.

Advantages

Why choose TETRON® pot bearings

01. Durable and low maintenance

  • Virgin PTFE
  • Stainless steel sheet

    • 02. Small footprint

    Moderate space required

    03. Tailor made

    Custom design to suit the type of structure and the needs of the project.

    04. Adaptable to all standards

    Compliance with all national and international standards.

    05. Cost-effective solution

  • Uniform distribution of loads through the structure
  • For vertical loads up to 50 000 kN
  • Small and moderate horizontal loads

    • 06. Certified product

    CE marking for EN standard and PTFE sliding material.

    07. Usable as a launching bearing

    For launching operations instead of temporary stools.

    08. Usable as an anti-uplift system

    Specific design available to withstand tension loads.

    TETRON CD naming system

    The naming system of TETRON CD pot bearings reflects the important characteristics of each product in the range, for maximum accuracy and transparency.
