Design Features

Design Features

  1. Tight Seals
    • O-Rings provide a tight seal without hindering swivel action
    • Accurately machined and micro-finished grooves provide for minimal seal wear
    • Available in Buna-N, Fluorocarbon (FKM), EPT, Neoprene, FFKM (Perfluoroelastomer) and other seal materials
    • PTFE seals are available as spring energized or silcone/Fluorocarbon (FKM) encapsulated
  2. True Ball Bearing Race Alignment
    • Body and tail sections are locked together by a double row of ball bearings
    • Raceways are machined to precise tolerances
    • Double raceway design assures proper alignment and prevents binding caused by temperature changes and heavy radial loads
    • Carbon steel swivels have hardened races to maximize load-carrying capability
  3. Protected Bearing Chamber
    • Protective inner O-ring seal prevents product from entering bearing chamber
    • Outer seal keeps rain, dirt, and other contaminants out
    • Both seals hold in lubrication
  4. Long-Life Bearings
    • Ball bearings are hardened, precision-ground steel
    • Stainless steel swivels have stainless steel bearings
    • All OPW® swivels are available with stainless steel bearings on special order
  5. Easy Lubrication
    • All OPW® swivels are pre-lubricated at the factory
    • All 3/4", 1", and submerged swivels are permanently lubricated
    • A grease fitting between races that accepts a standard grease gun is available for swivels that require field lubrication
    • Non-lubricated swivels are available on special order
  6. No Field Adjustment Necessary
    • Balls are held in place by factory-installed plugs that never need to be adjusted to maintain bearing performance
Convenience of Choice
  • Available in a variety of sizes beginning at 3/4" and up
  • Available in threaded, flanged, and butt welded ends
  • Steam jacketed and split flange swivels are also available
