Selden PBB60 Cheek Block R48 Curved Base 60 mm – Plain Bearing

The Selden PBB60 cheek block R48 (406-001-17) is specifically designed for fixed installations on smaller curved surfaces such as masts, booms or rounded deck profiles. The R48 base radius ensures optimal fit and load distribution on tighter curves compared to standard or larger radius cheek blocks.

This block belongs to the Selden PBB60 plain bearing range, making it ideal for applications with high static loads and controlled rope handling.

The construction combines a stainless steel reinforcement strap with glass fibre-reinforced composite cheeks, providing excellent strength, durability and resistance to line jamming. The 60 mm acetal sheave ensures smooth rope movement under load.

The compact cheek design allows secure installation using three M6 bolts, ensuring reliable performance even in demanding marine environments.
