Sail Care is proud to offer this great and innovative line of 3/8″ ball bearing blocks and other sailboat hardware from Viadana. Since 1961 they have been deeply involved in research, design, manufacturing, and marketing of top quality innovative hardware for sailors and their boats.
These ball bearing blocks are strengthened by using SS balls working between
two SS covers to share the load in a perfectly balanced way. Even under
strong stress for long periods the SS balls maintain their shape and
balance against the covers. Extremely smooth and tough!
