Spherical Plain Bearings utilize inner & outer rings with spherical sliding surfaces, and can accommodate heavy radial loads & bi-directional axial loads at the same time. They are produced in a wide variety of designs & materials to satisfy diverse demands such as those in the automation, construction, mining, transportation, off-highway equipment, farming & machine tool applications.
Sliding Surface: Steel on Steel - MoS2 treated
Suitable for Radial loads and single direction Axial (Thrust) load
Relubricatable through annular grooves & oil hole in outer ring
Standard designs utilize carbon chromium steel on steel which is hardened, phosphated and treated with Molybdenum Disulfide (MoS2) to reduce friction. Most designs can be relubricated through annular grooves & lubrication holes in the outer rings.
Bearings are also available in self-lubricating designs utilizing PTFE lined races offering a maintenance free solution with lower friction. For corrosive environments, many sizes can be supplied in stainless steel construction.
