Seldén PBB Triple Sheave Plain Bearing Block with Becket

The Seldén PBB plain bearing blocks are specifically designed for applications with very high and static loads. This version is triple sheave with becket and is perfect for complex purchase systems and applications requiring multiple line leads where maximum load capacity is essential.

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: Triple sheave with becket – ideal for systems with multiple lines and complex reeving

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: Ideal for backstays, checkstays, mainsheet systems, boom vangs, and complex halyard systems with multiple line leads.

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