Selden's 50mm Plain bearing range is one of the world's best-selling block ranges for very good reason, chosen by yacht manufacturers as OEM equipment, Selden's renowned quality at affordable prices is a winning combination.
From single blocks to doubles with twin cams the 50mm PBB range has a solution for most applications on board. Supplied with a 5mm Shackle and integral switch, the block can be used in a static position or allow free rotation.
Plain bearing blocks are typically used for heavy and static loads on board. If performance trimming is a requirement we would recommend Selden's Ball Bearing Block (BBB) range or for extreme loads, Roller Bearing Block (RBB) range.
As a guide, the 50mm range would typically be found on yachts from 25ft to 35ft using 10mm-12mm ropes.
