THK SA1 Series Spherical Plain Bearing

The SA1 Model Spherical Plain Bearing is a type that is widely used in Europe. Its outer ring is split at one point (outer rings with diameters of ø100 mm or larger are split at two points), and its reduced width and thickness compared to the SB model allow it to be used in space-constrained installations. The SA1 series is also available with contamination-protection seals on both ends (Model SA1…UU), making it suitable for applications requiring improved sealing and durability in harsh environments.
