Common Concerns Answered
How does a plain bearing block compare to a ball bearing block in terms of performance?
Plain bearing blocks, like this Barton Marine unit, offer excellent reliability and are well-suited for the load and speed applications they are designed for, such as on smaller craft or for pennant lines. While ball bearing blocks generally provide lower friction for very high-speed or high-load sheeting applications, plain bearings are robust and cost-effective for general use.
Is this pulley block durable enough for continuous use?
Yes, this Barton Marine pulley block is constructed for durability and high strength, suitable for its intended applications. The plain bearing design is inherently robust, minimizing potential failure points compared to more complex bearing systems.
Will this block be too small for my needs?
The Size 0 block with 20mm sheaves is specifically designed for smaller ropes up to 6mm. Its compact size and lightweight nature are advantageous for dinghies, day boats, and specific functions like lead blocks or flag pennants, where space and weight are critical considerations.
Frequently Asked Questions
What is the maximum rope diameter this Barton Marine Size 0 pulley block can accommodate?
This Barton Marine Size 0 pulley block is designed to accommodate rope diameters of up to 6mm (1/4").
What types of boats is this Barton Marine pulley block suitable for?
This pulley block is ideal for dinghies, day boats, and smaller craft. It is also suitable for use as a lightweight lead block or flag pennant block on larger yachts.
What is the difference between plain bearing and ball bearing sheaves on Barton Marine blocks?
Plain bearing blocks utilize a simple, direct contact between the sheave and the block body, offering reliability and robustness. Ball bearing blocks use a series of small balls to reduce friction, providing smoother operation at higher speeds or loads, but are generally more complex and expensive.
What is the weight of the Barton Marine Size 0 20mm Plain Bearing Pulley Block Cheek?
The Barton Marine Size 0 20mm Plain Bearing Pulley Block Cheek weighs only 13 grams (0.5oz).
Is this pulley block suitable for use on larger yachts?
Yes, this pulley block is suitable for larger yachts when used as an auxiliary block, such as for lightweight lead blocks, flag pennant systems, or other applications where a compact and lightweight high-performance block is beneficial.
