THK SB Series Spherical Plain Bearing

The SB Model Spherical Plain Bearing is the most widely used spherical plain bearing in Japan and is designed for heavy-load applications. It features wide spherical contact areas, allowing it to support large radial and thrust loads with high reliability. The outer ring is split at two points, enabling easy accommodation of the inner ring while maintaining high load capacity. This robust structure makes the SB model suitable for low-speed, heavy-load oscillating mechanisms.
