PTFE Bearing Pads.
For Pipe Slides, Equipment Supports,Architectural and Bridge Applications

Riload® is a bearing material which is made by molding TFE on each side and completelly through a sheet of perforated stainles steel. Riload combines the sliding properties of TFE with the strength and rigidity of steel

ADVANTAGES

Low Friction - High Load

The RILOAD surface provides a coefficient of friction as low as 0.02. The stainless steel core provides rigidity and uniform strength in all directions resisting "cold flow" and stretch of the TFE to the point that RILOAD bearing pads can carry loading in excess of 5,000 psi.

No Lubrication

RILOAD bearing pads are non-lubricated. Unlike "permanently lubricated" or "prelubricated" bearing materials, RILOAD cannot suffer deterioration, contamination, or washout of lubricant.

Almost Indestructible

RILOAD is unaffected by corrosives, solvents, temperature, (up to +400°F) moisture, sunlight, icing conditons and physical shock. The complete interlocking of the TFE to its metal reinforcement eliminates the use of any adhesive in the construction of RILOAD independent of the quality variables and the enviromental limitations of a cemented construction.

Positive fastening

RILOAD can be positioned positively by conventional mechanical means such as screws, bolts, rivets, masonry nails or tack welds. This eliminates the potential problems inherent in cemented bearing pads.

Economical

RILOAD's initial cost is low because it is a molded sheet, requiring no machining its installation cost is low due to the ease with which it can be fastened: and RILOAD maintenance costs are nil, because it requires no lubricant and is almost indestructible

 

Riload Applications
Structural Bearing Pads
RILOAD bearing pads are used to accommodate horizontal movement due to expansion, contraction and vibration in many types of buildings, bridges, and other structures. RILOAD'S low and unvarying friction minimizes the forces imposed on support members, while its positive fastening and permance provide assurance of satisfactory service for the live of the structure.

Equipment supports

Storage tanks, heat exchangers, pumps, compressors, and many other types of chemical refinery and general industrial equipment rest on RILOAD equipment supports, In these applications, RILOAD accommodates equipment movement in the most adverse environments with no maintenance and no diminishing of its bearing abilities

Pipe Slides

Slides are used to support process, steam, refrigeration, natural gas and other types of piping which must move due to expansion or vibration. In this application, RILOAD bering all the piping system to be designed for unlimited horizontal movement against minimum restraining force. This, together with its temperature tolerance, its resistance to the elements and its freedom from maintenance, makes RILOAD an ideal pipe support slide.

Riload Availability
Construction
Type 3 RILOAD is used for most bearing pad applications. Type 3 RILOAD has a nominal overall thickness of 3/32", consisting of 1/32" of TFE molded on each side of a .030" sheet of perforated type 304 stainless steel. The composition used for type 3 RILOAD is black in color and contians 15% glass reinforcement for optimum bearing properties.

Sizes and Shapes
RILOAD is available in 14"x18" sheets, used mainly for structural and equipment bearings. These RILOAD sheets can be sheared to size and formed into curved plates or bushings as required.

RILOAD pads can be furnished with any size of fastening hole. the standard location for the corner holes in rectangular pads is 1" from each edge.

RILOAD strips 3" and narrower are usually supplied with a single row of holes down the centerline, on 8" or shorter centers.
