  • For extra protection under severe conditions, auxiliary caps are also available
  • Spherical bearing design accomodates continual misalignment.
  • Collar is larger, thicker, and heavier to provide increased surface area contact with shaft.
  • Threaded cover and microlock design allows bearing clearance adjustment, off-the-shelf units to meet special requirements.
  • Wedges tight during operation, even if setscrews loosen.
  • Carburized (case-hardened) inner ring resists fracturing, even under heavy loads
