Common Concerns Answered
Are plain bearing blocks durable enough for heavy use?
While plain bearing blocks can exhibit wear over extended heavy use compared to ball bearing types, the precision acetal sheave and brass bearing in this Barton Marine block are designed for efficient load distribution and longevity in typical marine applications. For extreme, high-speed, or constant heavy use, regular inspection and potential replacement may be considered, but for most sailboat rigging, this block offers excellent durability and value.
How does this block compare to ball bearing blocks?
Ball bearing blocks generally offer lower friction, especially under lighter loads or at higher speeds. However, plain bearing blocks like this Barton Marine model are simpler, more robust, and often more cost-effective. The acetal sheave and brass bearing combination ensures very good low-friction performance, particularly when the load is significant, making it a highly practical choice for many rigging tasks.
Is this block suitable for offshore sailing?
Yes, the Barton Marine Size 2 Single Cheek Block is well-suited for offshore sailing due to its robust construction and significant safe working load of 370kg. The smooth operation provided by the acetal sheave and brass bearing ensures reliable performance even under challenging conditions commonly encountered during offshore passages.
