ThorPlas-Blue Wicket Gate / Linkage / Operating Ring Bearings



ThorPlas-Blue is a homogeneous, self-lubricating polymer bearing capable of withstanding operating pressures up to 45 MPa (6,527 psi) installed in a full-form, interference-fit configuration. It is an engineered thermoplastic offering very low wear in non-abrasive environments with several tests showing low friction and low wear.

Thordon wicket gate, operating mechanism and linkage bearings operate wet or dry and eliminate the cost, maintenance and pollution risk associated with greased bearings.

  • Self-lubricating to ensure performance in limited-motion applications
  • No galling from edge loading caused by minor misalignments or gate deflections
  • Can be machined on site to accommodate dimensional inconsistencies and avoid replacement parts
  • Quick stock and custom delivery to meet demanding rehabilitation schedules
WR1 Middle Bushings 001

All Thordon bearings can be easily machined and sized to final dimensions on-site prior to installation or easily line bored after installation to correct misalignment and dimensional inconsistencies encountered during turbine rehabilitation.
