Barton Sheaves

Barton Plain Bearing Blocks

All 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.

The Barton Ball Bearing Option

All Barton blocks from series 0 to size 7 offer the option of a high performance, low friction ball bearing sheave.

Friction is reduced by 23% when using a Barton ball bearing sheave compared to a plain sheave.

Plain bearing versus ball bearing sheaves

Use a plain bearing sheave for a high static load; for example mast base, (main and genoa) mast head and kicker or when the sheave will be under a high load and the sheave will turn infrequently. Use a ball bearing sheave where fast, constant adjustment is required, for example mainsheets or spinnaker sheets.
