Features & Benefits

  • Sealmaster® reduced maintenance mounted ball bearings with set screw locking are available in a wide variety of features:
    • 5/8" - 2 7/16" bore
    • Standard set screw locking only series only
    • 7 housing styles
    • Standard on all ER type bearings with cylindrical OD
  • Patented tapered lands on the outer ring shoulder to direct lubricant back in the raceway resulting in improved lubrication for significantly longer bearing life.
  • Sealed for life - no relubrication option.
  • Wide outer ring design provides increased grease capacity to lubricate the bearings.
  • Anti-rotation - pin & dimple system prevents the bearing OD from creep/rotation due to vibration over time while providing a full ± 2° of static misalignment.
  • Felt labyrinth seal with rotating flinger directs contamination away from the sealing surfaces. Optional single lip contact seal "C" offers a balance between wet and dry contamination and spring loaded V seal "U" for use in heavy contamination is present.
  • Black oxide standard on inner/outer rings and seal components inhibits corrosion.
  • Zone hardened inner race provides a fully hardened ball path while leaving the race extensions unhardened, allowing better set screw holding power.
  • Length through bore is longer than most competitors for greater shaft stability.
  • Land-riding brass retainer has high strength, minimizes friction and provides maximum grease circulation.
  • 120° balanced set screw position provides three-point balanced contact that minimizes vibration, reduces noise and improves reliability of the shaft assembly.
  • Precision manufactured, diamond faceted set screws improve clamping and resist backing out.
  • Solid base, pillow block, cast iron housing provides improved stability and resistance to shock and vibration.
  • Permanent metal nameplate allows for easy identification after years of operation.
  • Factory-filled with Sealmaster GOLDPLEX® HP lithium complex NLGI 2 grease.
