About PLUMMER BEARING

  • Housing: Usually made of cast iron or cast steel, the housing supports the bearing, holds lubricant, and is bolted to a base.
  • Bearing Insert: Commonly uses spherical roller bearings (for high loads) or self-aligning ball bearings.
  • Split Design: Most plummer blocks are split (upper cap and lower housing), allowing for pre-assembled shaft installation.
  • Sealing: Includes seals (e.g., rubber, labyrinth, or taconite) to prevent contamination, essential for harsh environments.
  • Lubrication: Equipped with grease nipples for easy, in-place re-lubrication. [1, 2, 3, 4, 5]
Common Applications
  • Conveyor systems
  • Mining and crushing equipment
  • Industrial fans and blower systems
  • Marine propulsion systems (shaft bearings)
  • Large electric motors and paper mills [1, 2, 3]
Plummer Block vs. Pillow Block
While often used interchangeably, a plummer block generally refers to a heavy-duty, split housing with an independent bearing. A pillow block often refers to a lighter-duty, single-piece, permanently sealed unit. [1]
Key Advantages
  • Self-Aligning: Accommodates shaft misalignment.
  • Easy Maintenance: The split housing allows for easy inspection and replacement of bearings without removing the entire shaft.
  • High Reliability: Designed for long life in high-power, high-load environments. [1, 2, 3, 4]
Popular manufacturers include SKF, NSK, and NTN. [1, 2, 3]
