Common Concerns Answered
Will the plain bearing wear out quickly?
While plain bearings can wear faster under very heavy or frequent use compared to ball bearings, this Barton block is constructed with precision components and an internal stainless steel frame to maximize durability for its class. It offers excellent value for many standard sailing applications.
Is this block suitable for very high load applications?
For applications demanding the absolute highest efficiency or exceeding its 370kg SWL, users seeking maximum performance might opt for a ball bearing alternative, though at a potentially higher cost. This block provides robust performance within its specified load limits.
What kind of performance can I expect from a plain bearing?
Users appreciate the robust construction and smooth operation for its bearing type. While not as friction-free as ball bearings, plain bearings offer reliable performance and are a cost-effective solution for many common rigging needs.
Frequently Asked Questions
What is the maximum rope diameter this Barton pulley block can accommodate?
The Barton Size 2 35mm Plain Bearing Pulley Block can accommodate a maximum rope diameter of 8mm (5/16 inch).
What is the Safe Working Load (SWL) for the Barton Size 2 35mm Plain Bearing Pulley Block?
The Safe Working Load (SWL) for the Barton Size 2 35mm Plain Bearing Pulley Block is 370kg (815lbs).
What is the difference between plain bearing and ball bearing blocks?
Plain bearing blocks use a low-friction material directly in contact with the sheave for rotation, offering simplicity and cost-effectiveness. Ball bearing blocks use a series of small balls to reduce friction significantly, providing higher efficiency and performance, especially under high loads or dynamic situations.
Can this block be used with wire rope?
This block is designed for use with synthetic rope up to 8mm in diameter. Use with wire rope is not recommended as it can cause premature wear on both the wire and the sheave.
What are the dimensions of the Barton Size 2 35mm Plain Bearing Pulley Block?
The dimensions of the Barton Size 2 35mm Plain Bearing Pulley Block are 93mm in length, 38mm in width, and 24mm in height.
