Cost Effective 50mm Plain Bearing Block
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 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.
