JM Clipper Oil/Grease Seals

Parker JM Clipper Oil/Grease Seals

The Clipper Oil Seal design features an integrally molded rubber fiber outer case and an elastomeric seal lip. The unique, nonmetallic construction will not rust or corrode and forms a gasket-type seal between the equipment housing and the seal outside diameter (OD).

Clipper Split Seals are known for being the easiest split seal to install because they do not require a cover plate to keep them in the housing. The composite OD provides the best retention of any split seal available. Replacing failed seals in with Clipper Split Seals saves on downtime and lost production expenses.

Clipper seals are available for shaft diameters from 0.250″ (6.35 mm) to over 65″ (1651 mm) in both standard and high-performance elastomer compounds. With over 10,000 tooled sizes, Clipper seals are readily available for most applications in either a solid or split design.

Stainless Steel Springs Are Standard on all Clipper Oil. Seals where the industry standard is a lower quality carbon steel. Clipper’s spring material provides improved lip loading at higher temperatures and resists the rust and corrosion that is common with lower-quality materials. The upgraded spring ensures consistent lip loading over the life of the seal.

Features, Advantages & Benefits:

The Clipper Oil Seal can be used as a direct replacement for metal case seals and provides the following benefits:

  1. Composite OD provides a gasket-type seal at OD for improved sealing in worn housings. Compression plates are not required for seal retention or lip loading. The tight press fit eliminates the need for a cover plate.
  2. Will not rust or corrode.
  3. Consists of a seal lip and seal OD to form a one-piece molded construction across the entire size range and a more robust design compared to gluing or crimping the seal lip to a metal case.
  4. Resists problems caused by thermal expansion when the seal case and housing are different materials.
  5. Eliminates seal damage during installation. The Clipper seal is known for its user-friendly installation.
  6. Nonmetallic construction allows splittable design.
  7. Composite material provides unique design capabilities; i.e. flange, buttons, mounting holes.
  8. Allows for faster delivery of non-stock items with no manufacturing delays caused by waiting on metal components.

JM Clipper Profiles:

Standard ProfilesApplications
LUP / LPDFor oil retention or grease retention. Typical applications: electric motors, gearboxes, pumps, fans, runout tables, paper rolls, work rolls, mixers and custom equipment.
RUP / RPDSplits — for grease retention — with oil, some seepage may occur. Typical applications: electric motors, gearboxes, pumps, fans, runout tables, paper rolls, mixers, and custom equipment. Split seals are designed for applications where equipment is unable to be disassembled due to time constraints.
LUPW / LPDWHigh runout conditions for applications up to 1" (25.4 mm) total eccentricity. For oil retention and low speeds.
LDSFor oil retention. Excludes light dust and fluid. Typical applications: electric motors, gearboxes, pumps, fans, runout tables, paper rolls, mixers, and custom equipment.
LDSWHigh runout conditions up to 0.125" (3.175 mm) total eccentricity. For oil or grease retention and low speeds. Typical applications: electric motors, gearboxes, pumps, fans, runout tables, paper rolls, mixers, and custom equipment.
SDSFor grease retention and exclusion of light dust and fluids. Typical light-duty applications.
SSFor grease retention and exclusion of light dust and fluid. Typical light-duty applications.
OLGenerally used in grease applications where bore rotates. Agriculture and ground-engaging equipment.
MIST / STMISTFor heavy-duty applications. Work rolls, paper rolls, backup rolls and custom equipment.
STLUPFor heavy-duty applications. Work rolls, paper rolls,
backup rolls and custom equipment.
LifeLineFor heavy-duty applications. Work rolls, paper rolls, backup rolls, and custom equipment.
PApplications for reciprocating service and low speed.
HApplications for rotary and reciprocating service. Reciprocating applications may require a bore plate.
HPThe high pressure (HP) seal is designed to handle rotary and reciprocating motions at high speeds and temperatures. Typical applications: pumps, compressors and custom equipment.
MPMP is typically used in grease and oil retention applications. Typical applications: electric motors, gearboxes, pumps, fans, mixers, and custom equipment.
DLDual spring-loaded lips are used when the separation of two fluids is required. The design is also used for high contamination applications in keeping out a dirty environment.
Clipper SliptiteWith the PTFE lip the seal can be used in dry running applications, at higher speeds, and accepts a broader range of chemical compatibility. Typical applications: electric motors, gearboxes, pumps, fans and custom equipment.
TMAL / TMASTMAL & TMAS seals are designed for corrosive chemical service and FDA applications.
RPDTPillow blocks.
TSSTypical applications: overhead cranes in steel mills, rotary drilling crown and travel blocks, draglines, hoists, and elevators. Also used on mine cartwheels, flywheels, idler wheels, and tapered bearings.
