Polymer bearing
expert igus, has been producing customer-specific piston rings, tailor-made in
terms of geometry and material, for about ten years. Now, the company is
supplying piston rings in a wide standard catalogue range. 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.
Clip rather than fiddle
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. The
“iglidur” piston rings are positioned, clipped and then snap in places. They
are increasingly replacing PTFE tapes that have to be punched or cut from raw
material in a time-consuming process, then inserted manually in a groove before
the piston is then slipped into the bore of the assembly. Moreover, the
straightforward handling of the piston rings reduces potential sources of faults
– there is no more deformation, and fitting errors are almost eliminated.

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 70 mm. From now, they can be delivered in specific materials and
dimensions within 10 days. All “iglidur” materials and standard bearing
dimensions are available on the basis of the company’s plain bearing catalogue
range. Popular piston ring materials (besides “iglidur J”) are the FDA-approved
material “iglidur A180”, “iglidur X” for use in chemicals and high
temperatures, the low-cost material “iglidur J4” and “iglidur J350” for
applications at over 90°C.
