Plain Bearing Blocks
Barton plain bearing blocks have a precision moulded acetal sheave running on a large diameter brass bearing, ensuring free running under the highest of loads.

Ball Bearing Blocks
With Barton’s unique super-low friction ball race systems, featuring acetal sheaves and delrin ball bearings, running on a large diameter centre boss. This allows Barton to fit more load-bearing balls, which ensure extremely low friction performance, even under high loads.

Break Loads
Where break and safe working loads are stated, it is assumed that all sheaves are evenly loaded as in a purchase tackle. Uneven loading, or loading of one sheave in a double or triple block, will severely affect strength quoted. If unsure, please seek further assistance.

Maximum rolling load on ball bearing blocks is the maximum free running load before ball bearings will distort.

Fixed Eye
With plain attachment eye

Reverse Shackle
Removable shackle that can be set in-line or at 90° to the sheave

Snap Shackle
