Clipper® Oil Seals
Clipper Oil Seals are the anchor of Parker’s rotary seal product line. The Clipper design features an integrally molded rubber/aramid fiber outer case (heel) and an elastomeric seal lip. This unique, nonmetallic heel construction will not rust or corrode and has the added benefit of forming a gasket-type seal between the equipment housing and the seal outside diameter. Easy-to-install solid or split configurations reduce down time.
FlexiSeals are used where elastomeric seals fail to meet the temperature range and when speeds are relatively low (<1000 fpm) and pressures are high (up to 10,000 psi). The “spring-energized” U-cup design utilizes a variety of jacket and lip profiles, spring types, and materials. Either a flange or an o-ring on the OD keeps the seal fixed in the bore as the shaft rotates.
Parker's FlexiCase seal is a metal-cased rotary lip seal
suitable for applications where elastomeric lip seals fail
and mechanical seals are too costly. The filled PTFE
element provides greater chemical compatibility, wider
temperature ranges, higher pressure capabilities, and
longer life than elastomeric lip seals.
FlexiLip™ seals incorporate a deflected sealing lip geometry. Anti-rotational devices such as flanges and O-rings are often utilized to prevent the seal from rotating with the shaft. FlexiLip™ seals are suitable for sealing corrosive and abrasive media. A wide range of geometries and material are available, depending on specific application requirements.
Parker Oil Seals include a multitude of designs featuring different lip and case styles in varying combinations to match lubrication, operating conditions, regulatory requirements, and other application parameters for rotating equipment. Standard lip and case material combinations are available as well as over 100 special profiles, plus custom design engineering capabilities for applications with unique operating conditions.
ProTech bearing isolators are the
leading technology in bearing protection with their unitized, two-piece design, providing zero lubricant leakage and total exclusion of
contaminants. PTFE and metallic designs available in flanged and non-flanged designs to suit application requirements and various shaft orientations.
