Spherical Plain Bearing Model SA1 Model SA1

This type of Spherical Plain Bearing is widely used in Europe. The outer ring is split at one point (outer rings with diameter of ・100 or thicker are split at two points), and the width and thickness are smaller than model SB. Thus, this model can be used in small spaces. Types attached with contamination protection seals on both ends (model SA1…UU) are also available.
