1 Configure the Support for Sliding Movement

Where horizontal travel is provided through sliding, this bearing combines elastomeric load and rotation accommodation with a PTFE-to-stainless-steel interface. Sliding surfaces must be kept clean, and their dimensions coordinated with design travel and specified allowances.

2 Define the Sliding Assembly

· Elastomeric body: construction and dimensions confirmed against the design.

· PTFE surface: configuration, dimensions and friction requirements specified.

· Stainless steel mating plate: usable area, finish and attachment coordinated.

· Guides, restraints, protection and transport fixings included only as scheduled.

4 Applications and Buying Questions

For girder bridge supports designed to use a sliding interface.

Does a white PTFE face mean the assembly is complete? No; the matching sliding plate and connections must also be specified.

Is movement automatically limited to one direction? No; guided movement requires a designed guidance or restraint arrangement.

5 Request a Sliding Assembly

Send reactions, travel in both directions, rotations, mating-plate requirements and supply boundaries to ZSJH.
