GUIDELINES FOR THE CHOICE
The data in the table refer to the handling of materials with a stiffness such as to keep flat the contact surface with the rollers.
Otherwise the values may be lower.
Load values produce an elastic deformation such as to prevent the regular rotation of the rollers, which come into contact with the ribs of the aluminum profile. At these load values however, no permanent deformation of the material occurs.
Load values higher than those reported in the table produce a deformation such as to prevent the rotation of the rollers, that come into contact with the ribs of the aluminum profile. Loads higher than 100N for a single roller cause a reduction in the rolling resistance.
The load values exceeding the ones indicated in the table determine a reduction in the rolling resistance. However, no significant permanent deformation of the material occurs to these load values.
Load value that limits the smoothness of the balls inside its support, at low sliding speeds. At this value of load, however, no permanent deformation of the material occurs. For higher sliding speeds, it is
necessary to refer to the chart at the side.
Load concentrated in the centre, roller track supported in two points.
