Seldén PBB Plain Bearing Block, Violin Block
The Seldén PBB plain bearing blocks are specifically designed for applications with very high and static loads. This version is constructed as a violin block, making it perfect for applications requiring different sheave diameters within one block to minimise friction in the system and ensure optimal line guidance.
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: Violin block – ideal for purchase systems with different sheave diameters for optimal line guidance
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 mainsheet systems, boom vangs, traveller systems, and complex trimming systems requiring different reeving ratios.
