Features & Benefits

  • Sealmaster® mounted ball bearings with double set screw locking are available in a wide variety of features:
    • 7/8" - 4 15/16"
    • Standard and medium duty series
  • Double set screw locking incorporates extended inner races on both sides of the ball path resulting in a total of 4 set screws (2 on each side) for better load distribution, resulting in greater holding power when operating at high speeds and when vibration may be present.
  • 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.
  • Direct lube - pin & dimple system provides a direct lubrication path into the bearing, eliminating the need to channel grease around a lubrication groove common on standard mounted ball bearing units.
  • Felt labyrinth seal with rotating flinger directs contamination away from the sealing surfaces. Alternate seal options available upon request, see Sealmaster Custom SelectTM for more information.
  • 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.
