Pillow Block Bearings

Triangle Manufacturing is an American pillow block bearings manufacturer

Triangle's heavy-duty pillow block bearings are self-aligned lubricated bearings offering a longer life-span and quieter operation with a much smoother rotation with the shaft. Self-aligning bearings come in handy when your shaft is misaligned with the bearing. This will save you time and extra machine costs to fix your application. Applications include agriculture, lawn and garden, HVAC and air handling, automotive, recreational vehicles, food processing, vending, construction, manufacturing, pulp & paper, solar, mining, water treatment, aerospace, quarrying and mining.


Pillow block bearings are available with the following options:

  • Bearing shaft sizes: range from 1/4 inch to 1.75 inch
  • Bearing inserts: optional bushings and cushions
  • Bearing ball materials: bronze sleeve bearings, sintered bronze, sintered iron, cast iron and plastic

(and is today known as Oshkosh Corporation®), he ventured out on his own to establish Triangle Manufacturing Company in 1922.
