Spring-loaded spindle
The spring-loaded spindle is the simplest type of spindle and is extremely easy and quick to fit and remove. The side profiles used should be connected to one another with
cross-ties of adequate strength. Care must be taken to ensure that the distance between the two profiles has at least 1 mm play in relation to the installation length (EL) of the
fitted roller.
One must also check that there is adequate space available for fitting the roller in the side profiles. Due account must be taken of the space requirements indicated in the
illustration below and in the formula. An excess (d1) of approx. 0.5 mm larger than the diameter of the spindle is sufficient in most cases.
Different types of spindle are available on request.
Female threaded spindle
The roller is fitted with bolts in the profile. Therefore, the spindle is extremely strong. The roller spindles and profiles stabilise each other, so compared with fitting loosely
the rollers can be subjected to higher loads. To strengthen the profiles, it may not be necessary to use cross-ties. Rollers can be simply removed from or fitted in an existing
profile at any time.
