DYMAT® Structural Bearings

Flat Bearings

Design

The 3/16 Inch Problem Solver

Use the DYMAT® flat bearing in any application where a full contact bearing and a low profile is needed. In Europe, flat roof designs have the bearing on all walls at the roof to prevent cracking of roof and walls.

DYMAT® Flat Bearings consist of two layers of a special PTFE compound 1/32 inch thick bonded to 1/16 in Neoprene. The two layers are shipped together as an expansion bearing package with the edges taped together
