A Sleeve Bearing also known as a plain bearing is designed to support rotational or sliding movement between two parts. Which are separated by a sliding layer of composite material. The inner and outer rings of spherical plain sleeve bearings are designed to have a smooth and spherical surface which allows them to maintain contact with the sliding layer.Attributes:• Material is processed with carburized quenching and tempering to give hardness and strength• Provided with an internal groove cut to give better lubrication and heat dissipationApplications:A Sleeve Bearing is used in the Hydraulic Cylinder to move the Cylinder Rod without any friction.
