The RBB60 Cheek Block with M8 mount is a high-load roller bearing block designed for fixed installations. Made from black anodized aluminium and featuring Torlon® roller bearings, it offers durability and performance under dynamic loads.

Polymer thrust bearings help resist side loads, while a polymer washer insulates stainless steel components from aluminium, preventing corrosion.

Ideal for halyards, control lines and spinnaker sheets in applications where fixed mounting is required.

Seldén Roller Bearing Blocks (RBB) is our performance range and unrivalled in terms of low friction for the trimmer to endure driving the boat forward for longer periods of time.
