Common Concerns Answered
Are plain bearing blocks as effective as ball bearing blocks?
For the intended applications of this Barton Marine block on smaller vessels, plain bearings offer a reliable and durable solution. While ball bearings are typically used for extremely high-performance or very high-load applications, plain bearings provide robust performance and longevity for dinghies and dayboats.
Is this block suitable for high-load applications on larger boats?
This Barton Marine Size 3 pulley block is specifically designed and optimized for smaller to medium-sized sailing vessels, such as dinghies and dayboats. For larger boats requiring higher load capacities, a block with a larger sheave diameter and potentially ball bearings would be recommended.
