Common Concerns Answered
Will the plain bearing create too much friction?
Plain bearings can exhibit higher friction than ball bearings, particularly under heavy loads or in the presence of grit. However, for the intended applications of dinghies and dayboats, and with proper maintenance, the performance is generally satisfactory for most users.
Is the 45mm sheave large enough for my needs?
The 45mm sheave is optimized for compact applications on smaller craft, accommodating ropes up to 10mm. For extremely high-load applications or very large diameter ropes, a larger sheave diameter might be preferable, but this block excels in its intended size class.
How does this compare to ball bearing blocks?
Ball bearing blocks offer superior low-friction performance, especially under load. This Barton block utilizes plain bearings, providing a durable, cost-effective, and lightweight solution ideal for many sailing scenarios where ultimate friction reduction isn't the primary requirement.
