Self-lubricating Radial Spherical Plain Bearing

Self-lubricating radial spherical plain bearings are found in applications where self-lubricating is required.

Where They Are Used

In low speed, and heavy radial load applications and where self-lubricating is required or re-lubrication can’t be performed.


  • Maintenance free and saves re-lubrication system in the housing or shaft
  • Support very high radial loads
  • Very long service life


  • Sliding surfaces are metal to PTFE
  • Inner ring and outer ring are made of hardened rolling bearing steel
  • Single or double fractured outer ring
  • Spherical surface of inner ring is chrome plated
  • High strength PTFE fabric with low coef. of friction is bonded to spherical surface of outer ring
  • They can support very high radial loads
  • Operating quietly
  • They are self-aligning in all direction
