Seldén PBB50 Single Sheave Plain Bearing Block with Swivel and Cleat / 50mm Sheave

Seldén PBB Single Sheave Plain Bearing Block with Cam Cleat

The Seldén PBB plain bearing blocks are specifically designed for applications with very high loads. This version is single sheave with integrated cam cleat and is perfect for halyards, boom vangs, mainsheet systems, and similar applications where high static loads occur.

Technical Details

• Sheave material: Acetal – durable and low friction
• Axles: High-strength, stainless steel for maximum strength and corrosion resistance
• Housing: Robust composite material for low weight and high stability
• Swivel: Can be locked in longitudinal or transverse position for maximum flexibility in mounting and use
• Block type: Single sheave with cam cleat – ideal for safely and quickly securing halyards or sheets directly at the block

Special Features

• Plain bearing technology: Optimised for very high and static loads. The higher the load, the better the block performs compared to ball bearing blocks.
• Long service life: The large contact surface in the plain bearing distributes the load, reducing wear and increasing durability.
• Versatile application: Perfect for backstays, checkstays, mainsheet systems, boom vangs, and halyard systems.

* Based on the working load of the cam cleat.

Note: Blocks are essential components on any sailing yacht. Check them regularly to ensure safety and performance under all conditions.
