Fabreeka® - PTFE Bearing Pad - Bearing Pad
Verified by manufacturer 5 months ago
Fabreeka® Pad bonded to Teflon® (PTFE) surface.
Application
Fabreeka-PTFE bearing pads are used for conditions where it is necessary to accommodate lateral movement (expansion). The PTFE provides a low friction sliding surface on the Fabreeka bearing pad, which distributes high compressive loads and accommodates rotations. In a structural bearing design, polished stainless steel is typically used as the smooth surface that the PTFE slides against.
Description
Fabreeka-PTFE bearing pads are manufactured using Fabreeka pad material with a Teflon® (PTFE) surface. The virgin Teflon is heat cured to the Fabreeka pad using a rigid, laminated thermoplastic (LTP). The rigid LTP layer prevents the PTFE from expanding/flowing under compressive load and rotation (also known as “cold flow”), as the bearing pad compresses.
Features and benefits:
- Commonly used in structural expansion bearings and pipe slides.
- Bearing pad meets AASHTO 18.4.9.1, MIL-C-882 and most state DOT specifications.
- PTFE (Teflon) surface provides low friction for expansion.
- Accommodates lateral movement and rotation.
- Allows for rotations up to 0.02 radians under high pressure.
