Roller supports are indispensable for the installation of rigid and insulated hoses that bear a heavy vertical load and in situations where friction caused by dilation of the hose at the point of support has to be eliminated.

The body of the roller and the cage are made of galvanized carbon steel, while the pin that holds them together is in AISI 304 stainless steel, with self-lubricating bushings made of low static-dynamic friction PTFE.

Giorgi Engineering produces various typologies of rollers, to respond to the different vertical loads and hose diameters. Certain models allow a 60 mm shift to compensate for misalignments or lateral movements.

INSTALLATION

Roller supports can be welded or bolted to the structure to which they are to be fitted.

When dealing with particular pipes, e.g., wide diameter, reduced thickness, high linear weight, it is advisable to install supports close to each other and reinforce the points of support. Saddles should be used for insulated pipes to avoid contact between the roller and the insulating material.

ROLLER SUPPORTS: PE

These supports, which are conical in shape, are used for pipes without insulation as they allow a degree of axial alignment. The cage and the roller are in white galvanized steel, the pin is in stainless steel and the bushing is in low static-dynamic friction PTFE.

ROLLER SUPPORTS: PM

PM roller supports are also used for non-insulated pipes, but unlike the PE model they are not conical in shape. This characteristic makes them ideal for situations in which the pipe has to move slightly to compensate for movements generated by other parts of the system to which it is connected. They are frequently used internally as a lateral guide (?). The cage and the roller are in white galvanized steel, the pin is in stainless steel and the bushing is in low static-dynamic friction PTFE.

ROLLER SUPPORTS: PT and SEL

These models are used for insulated pipes. They are composed of the support (PT) and the saddle (SEL), the top part of which is welded to the steel pipe, while the bottom part rests on the roller so that the saddle is incorporated into the pipe which can then slide along the roller. The pipe can then be insulated. The cage and the roller are in white galvanized steel, the pin is in stainless steel and the bushing is low static-dynamic friction PTFE.
