Lubrication-free piston rings

Ready-to-fit clip-on polymer piston rings are increasingly replacing PTFE tape, as they can be fitted with one simple movement.

The clip-type guide rings are used in valves, actuators and lifting components in armatures, the food and drinks industry, chemical and medical technology, to name but a few.

The igus piston rings are lubrication free, wear-resistant, have a defined clearance and are dimensionally stable even with edge loads. This makes the “iglidur” piston rings suitable for linear and/ or rotary, lifting or pivoting movements.

One major advantage – in addition to being lubrication free – is they are fast fitting. The ready-to-fit piston rings are fitted in only one movement, into an undercut machined in a bore or in a groove of a shaft.

Polymer piston rings made of the tribo-optimised universal material “iglidur J” are now available ex stock in 13 dimensions for shaft diameters from 10 to 70mm.

The compact AC/DC power supply units supply 100 per cent output at ambient temperatures of up to 60°C. They can be used in a wide temperature range between -25 and 70°C and therefore also in outside areas.
