Seldén PBB100 Plain Bearing Double Block - flat base
When maximum power transfer and longevity are essential, the PBB100 truly shines: Seldén's double-sheave plain bearing block is designed for working loads up to 4 tons and handles ropes up to 20 mm in diameter with ease. Milled aluminum components, insulated stainless steel parts, and a sophisticated bearing system make it a reliable choice for demanding sheet and tackle systems on board.
The mounting screws (3 × M10) are not included – please have suitable stainless steel screws ready before installation. For a long service life, disassemble, clean, and lightly grease the plain bearings after the season or if audible resistance is noticed.
