Seals boost food production safey
SKF Economos' new seals can be quickly and simply found with standard metal detection equipment should any small pieces fall into the product being processed.
The slide units are made of hardened, bearing-quality, stainless steel and have moulded ball recirculation paths.
All parts of the system are corrosion resistant.
Longer carriages, for higher load capacities, and wider carriages, for higher moment stiffness, are available.
Mounting is easy, with tapped holes in each carriage.
The rails are through drilled and counter bored.
If a plain top surface is required, blind threaded holes in the rail's underside are available.
The stainless steel balls circulate in two paths between the rail and slide unit.
The gothic arch configuration of the raceway results in a guidance system with good rigidity, which provides a high load rating in all directions.
An external ball return path enables the use of an extra large radius, ensuring quiet running even at higher speeds.
The use of an external return path also avoids unnecessary weakening of the slide unit and therefore allows greater stiffness of the system.
SKF's miniature profile rail guides are manufactured in two accuracy classes: P1 and P5.
Miniature profile rail guides are available in two different preload classes, with preloaded guides having approximately twice the stiffness of those without.
The maximum standard length for miniature profile rail guides is 300 to 900mm.
For longer runs, separate lengths can easily be joined together.
