Barton Ball Bearing Blocks feature a unique super-low friction ball race system, comprising acetal sheaves and delrin ball bearings running on a large diameter centre boss.
The Barton ball bearing design fits in more load-bearing balls, and consequently promotes extremely low friction performance, even under high loads.
