Spherical plain bearing are designed to carry radial and axial loads in a small envelope, and are ideal for static and oscillatory applications where moderate misalignment may exist. The bearing design consists of a spherically ground inner ring housed in a mating outer ring without any rolling elements. These bearings offer the following advantages:
Rings manufactured from hardened steel help to deliver consistent, reliable performance.
Phosphate-treated rings coated with molybdenum disulfide (MoS2) minimize friction of contacting surfaces.
Simplified housing and shaft designs reduce installation time.
Designs that accommodate misalignment result in superior performance for low-frequency oscillating applications.
