Product Description
Fabreeka-PTFE bearing pad is comprised of the original fabric reinforced, elastomeric pad developed in 1936. Fabreeka-PTFE pad is used to accommodate construction irregularities such as rotation and non-parallel load bearing surfaces, while also providing a sliding surface to accommodate expansion. The Fabreeka-PTFE bearing pads are manufactured with a Teflon® surface for use in expansion bearings and pipe slides. Fabreeka pad is scientifically constructed to give years of service under the most severe operating conditions.
Fabreeka-PTFE pad can be used in structural expansion bearings, slide bearings, pipe clamps and as pipe support pads.
KEY FEATURES/BENEFITS
- Pads can withstand compressive loads perpendicular to the plane of laminations of not less than 12,000 psi before breakdown.
- Pads meet AASHTO standard specification for fabric-reinforced bearing pads.
- Low coefficient of friction via PTFE surface.
Technical Specifications
Fabreeka bearing pad is manufactured of all new (unused) materials and composed of multiple layers of prestressed 50/50 cotton-polyester blend duck, 8.1 ounce per net square yard, duck warp count 50 ± 1 threads per inch and filling count 40 ± 2 threads per inch, impregnated and bound with a high quality, oil-impervious nitrile rubber compound, containing rot and mildew inhibitors and anti-oxidants, compounded into resilient pads of uniform thickness.
The Polytetrafluorethylene (PTFE) self-lubricating surface is a 100 percent virgin (unfilled) polymer bonded to a rigid confining substrate. The substrate limits the flow (elongation) of the confined PTFE to not more than 0.009″ under a load of 2,000 psi. A range of PTFE thicknesses can be supplied.
Fabreeka-PTFE pad is impervious to most oils and is resistant to the effects of steam, water, mildew and brine. The effective temperature range is -65 ° F to 200 ° F.
The durometer of the Fabreeka pad is 90±5 (Shore A).
Fabreeka-PTFE pad is manufactured in nominal thicknesses of:

FAQS
Can the Fabreeka-PTFE bearing pad material be cut to size in the field?
Yes. The Fabreeka-PTFE material can be cut to size in the field using a band saw. Care should be taken so as not to damage the PTFE.
Can holes or slots be cut in the field?
Yes. Holes or slots can be cut or drilled in the field using a fine tooth hole saw.
What is the recommended thickness of PTFE pad for use in a pipe clamp application?
Recommended thickness depends on the pipe diameter. Please contact Fabreeka’s Engineering department at 1-800-322-7352 or info@fabreeka.com for assistance on your application.
What is the purpose of the PTFE surface when the material is used in a pipe clamp?
PTFE (Teflon) surface provides a layer of insulation for the Fabreeka pad. PTFE can be exposed to 400°F, while the Fabreeka pad is limited to 220°F. PTFE also allows for the pipe to expand/move within the clamp by providing a low coefficient of friction.
What epoxy/adhesive should be used to bond PTFE pad to steel?
Fabreeka #700 Epoxy should be used to bond Fabreeka-PTFE pad to steel. The bottom of the Fabreeka pad should be buffed and the steel surface roughed up or sandblasted.
What type and thickness of PTFE should I use for my application?
The Fabreeka-PTFE pad type and thickness depends on the application. When used in a structure as an expansion bearing with rotation, the thickness of the Fabreeka-PTFE pad is calculated using the design guidelines in the Fabreeka structural expansion bearing literature .
