Common Concerns Answered
Is this pulley block suitable for very high-load or high-speed applications?
For exceptionally high-load or high-speed applications, users might prefer a ball bearing block. However, this Barton plain bearing block offers excellent performance and durability for a wide range of standard sailing uses.
How does the plain bearing compare to ball bearing in terms of longevity?
While plain bearings can exhibit wear faster than ball bearings under extremely heavy, continuous load cycles, they offer a simpler, more robust design with fewer moving parts, reducing potential failure points in typical sailing conditions.
What is the customer sentiment regarding this block?
Customer feedback is largely positive, with users frequently commending the block's durability, its effective performance relative to its size, and its overall value for money in marine rigging applications.
Frequently Asked Questions
What is the maximum rope diameter this Barton pulley block can accommodate?
The Barton Size 2 35mm pulley block is designed to accommodate a maximum rope diameter of 8mm (5/16 inches).
What is the Safe Working Load (SWL) for the Barton Size 2 35mm pulley block?
The Safe Working Load (SWL) for this Barton pulley block is rated at 370kg (815lbs).
Is this pulley block suitable for high-load applications?
Yes, with a Safe Working Load of 370kg (815lbs) and a break load of 740kg (1630lbs), this block is suitable for many high-load applications common in sailing, though extremely dynamic loads might warrant consideration of other bearing types.
What is the difference between plain bearing and ball bearing blocks?
Plain bearing blocks utilize a smooth surface for rotation, offering simplicity and durability, while ball bearing blocks use rolling elements (balls) to reduce friction, providing superior performance under very high speeds or loads.
Can this block be used with synthetic or natural fiber ropes?
Yes, this block is suitable for use with both modern synthetic fiber ropes and traditional natural fiber ropes, provided they are within the specified 8mm (5/16 inch) diameter limit.
