Selden High Load Plain Bearing Blocks

Selden High Load Plain Bearing Blocks

Selden High Load Plain Bearing Blocks are optimized for wires or Dyneema/Spectra core. Designed for wire applications subject to rig loads, e.g. backstays.

Technical features include stainless steel, electro polished cheeks, anodised aluminum sheave and polymer plain bearing bushing. The outer side plates increase the breaking load, but still optimizing the weight. Sheave is V-shaped for wires with light holes to reduce weight. Two polyamide washers on pin/ bushing to reduce play between wire terminal and cheeks.
