This is accomplished byusing non-contact labyrinth seal technology. ProTech featuresthe most effective labyrinth design for both dirt exclusion andoil retention and is far superior to isolators that rely oninternal O-rings or other internal seals for sealability. If youwant more than just an O-ring for bearing protection — stepup to ProTech!88ProTech Bearing IsolatorLS Profile03/28/068-1 Parker Hannifin CorporationEPS DivisionToll Free: (800) 233-3900www.parkerseals.com
