Product Code:: ESA 0250 0219 040 R3
ESA/ISA TYPE PISTON/ROD GUIDE RING
This guide ring type is used to avoid direct
contact between cylinder head and rod, and
between piston and sleeve, since they are mainly
made of aluminium. It’s also used to lead all the
system.
The guide rings are moulded in non-abrasive
and self-lubricant material, especially studied to
improve the linear sliding.
The profile presents chamfers both sides for
easier installation of rod and piston.
