Ring Jewels
Serving as radial/sleeve bearings, Ring Jewels are used with straight cylindrical shafts. They offer flexibility due to their many combinations with endstones. Straight holes restrict lateral movement, but require accurate alignment when the clearance between pivot and bearing is tight. Olive holes offer lower friction with pivots and permit assembly adjustment. Bombés provide minimum contact with pivots for light, intermittent end thrust. Where thrust load is continuous, an endstone is usually combined with the ring jewel.
