Seldén PBB 100 Double Block with D-Shackles Swivel Plain Bearing

The Seldén PBB 100 double block is a top-tier plain bearing block designed for very high working loads on larger sailing yachts. This double block is supremely suited for sheets, halyards and other heavily loaded line systems where reliability and smooth operation are of paramount importance. The two sheaves provide excellent load distribution and offer a significant mechanical advantage when handling heavy rigging.

The cheeks and sheaves of this Seldén PBB 100 double block are manufactured from black anodised aluminium, resulting in a robust construction with an attractive appearance. The stainless steel is insulated from the aluminium to prevent galvanic corrosion, a crucial detail for long-term use in the marine environment. The plain bearing offers reliable and low-maintenance operation, ideal for cruising applications where consistent performance is more important than minimal friction. The locking screw makes it easy to switch between swivel and fixed positions, making the block versatile in its applications.

With an impressive safe working load of 4000 kg and a breaking strength of 8000 kg, this double block is among the strongest in the Seldén PBB series. The block comes with straight D-shackles with a pin diameter of 12 mm for a secure and reliable attachment. The swivel attachment point ensures the block is always optimally aligned with the line direction. This block is easy to disassemble for maintenance, further extending its service life.
