Wichard Single Block 55mm for 12mm Rope

The Wichard 64105 Single Plain Bearing Block is designed for sailing applications where strength, reliability and simple operation are essential.

Its 55 mm composite sheave runs directly on a stainless steel bush, creating a robust plain bearing system with very few moving parts. This construction is particularly suitable for high loads and relatively static operations, providing dependable performance in demanding rigging systems.

The block is designed for 12 mm rope and combines a substantial 720 kg working load with compact dimensions and a weight of only 179 g.

Swivel Head for Flexible Installation

The swivel head allows the block to rotate and align more naturally with the direction of the load. Wichard’s universal head design also provides a wide choice of fastening options, making the 64105 easy to integrate into different rigging arrangements.

This flexibility makes it particularly useful where the direction of the rope or load may vary during operation.

Strong Marine-Grade Construction

The head configuration and load straps are manufactured from 316L stainless steel, while lightweight POM cheeks protect the sheave.

The sheave itself is manufactured from composite material, providing a strong and lightweight construction suitable for regular marine use.

With a breaking load of 1500 kg, the Wichard 64105 delivers excellent strength for its size.
