Seldén BBB 30 Triple Block fixed ball bearing

The Seldén BBB 30 triple block is a robust and versatile ball bearing block with three sheaves, designed for medium loads on sailing yachts. This triple block offers a significant mechanical advantage thanks to its three parallel sheaves and is the ideal choice for purchase systems where high load reduction is required. The BBB 30 series from Seldén is specifically developed for applications on medium-sized sailing yachts, where higher loads occur than with the smaller BBB 20 series, but where rigging weight remains an important factor.

The stainless steel ball bearings in this Seldén BBB 30 triple block guarantee an exceptionally smooth and low-friction operation, even under higher dynamic loads. This is essential in triple blocks, where the line runs over three sheaves and the cumulative friction can have a significant impact on the required pulling force. The block body is manufactured from glass-fibre reinforced polyamide, a material that excels in combining low weight with high strength. Weighing just 77 grams, this BBB 30 triple block is remarkably light for its load capacity, making it a popular choice for both cruising and racing sailors who value weight savings.

The fixed head allows attachment with a D-shackle or line, enabling the block to be mounted at various positions on board. The central hole can also be used as a becket, providing additional flexibility when building purchase systems. With a safe working load of 600 kg and a breaking load of 1200 kg, this triple block is engineered to handle the considerable forces encountered while sailing in varying conditions on medium-sized yachts. Whether you are building a multi-part tackle for your mainsheet, configuring a backstay system or redirecting a halyard through multiple blocks, the Seldén BBB 30 triple block delivers the dependable performance you expect from Seldén.
