Selden RBB60 Cheek Block – 60 mm Roller Bearing Deck Block M8

The Selden RBB60 Cheek Block (406-201-10) is a compact and robust deck-mounted block designed for high-load and dynamic sailing applications. Its fixed cheek construction allows secure installation directly onto the deck, making it ideal for guiding control lines in demanding setups.

Equipped with Torlon® roller bearings, this block delivers extremely low friction even under high loads, ensuring smooth trimming, efficient load transfer, and reliable control. The integrated acetal ball bearings stabilise the sheave when subjected to side loads, maintaining consistent performance in all sailing conditions.

The block is manufactured from precision-machined, black anodised aluminium, offering excellent corrosion resistance and durability in harsh marine environments. Insulating washers prevent galvanic corrosion between stainless steel and aluminium components.
