Seldén Plain Bearing Block PBB100 – double with swivel shackle

When every kilogram counts on board and the line is rarely perfectly centered: The PBB100 is Seldén's high-performance block for demanding sheet and tackle systems. With a working load of 4,000 kg and a self-aligning swivel shackle, it reliably holds up even under extreme loads – and can be quickly disassembled without special tools if necessary.

Tip: For maintenance, completely dismantle the block, check bearings for abrasion, and lightly grease them with a waterproof, acid-free grease – this significantly extends bearing life.
