Schaeffler UK has launched a range of stainless-steel rod ends for pneumatic cylinders, control and automation equipment, machines used in food and beverage and chemical and medical applications.
The Elges range offers a maintenance-free unit that is resistant to most media, including food, beverages, chemicals and water for machine designers and builders.
The rod ends are made from alloy steel and each comprise a housing with internal or external threaded stem (spigot) and a maintenance-free spherical plain bearing.
The housing and stem conform to DIN ISO 12 240-4 dimension series K and have a radial spherical plain bearing and a right- or left-hand internal or external thread.
The sliding contact pair incorporates corrosion-resistant steel and a corrosion-resistant PTFE-bronze film that is fixed in the outer-ring crowned surface.
This sliding contact is intended to ensure maintenance-free operation.
All internal threaded rod ends in the range are also available with European Fluid Power Committee (CETOP) mounting dimensions in accordance with ISO 8139 for pneumatic cylinders.
The rod ends are suitable for a range of applications, including pneumatic systems, control and automation equipment and machines destined for the food and beverage processing sector, abattoirs, chemicals, medical, aerospace and shipbuilding.
The rod ends are also suitable for use on buses and rail vehicles.
They are available with diameters from 5mm up to 30mm.
The housing and stem are manufactured to DIN 13 and the bore tolerance of the spherical plain bearings is H7.
The rod ends can be used in operating temperatures from -10C to +80C.
Typically, X105CrMo17 (material number 1.4125) corrosion-resistant steel is used for the inner ring of the rod ends.
For the outer ring and housing, X8CrNiS18-9 (material number 1.4305) or X5CrNi18-10 (material number 1.4301) are used.
