THK RBI Series Link Ball

A link ball is a spherical slide bearing with an integrated ball stud, designed to provide smooth motion with extremely small clearance. It is particularly suitable for link mechanisms in automatic machinery, where large oscillation angles and high wear resistance are required.

The RBI Model Link Ball uses a high-strength zinc alloy holder, with the mounting bolt aligned on the same axis as the holder, allowing it to receive axial loads. Grease sealed inside a protective boot ensures high lubricity and long wear life, making it suitable for enclosed or exposed environments.
