IKO PILLOBALLs are compact self-aligning spherical bushings which can support a large radial load and a bi-directional axial load at the same time. These bearings are available in insert type, die-cast type and lubrication-free type depending on the type of sliding surface. In the insert type, a spherical inner ring makes contact with a special copper alloy bushing with superior run-in properties. In the die-cast type, a spherical inner ring makes direct contact with the bore surface of the body of special zinc die-cast alloy. In the maintenance-free type, a spherical inner ring makes contact with a special self-lubricating PTFE liner. Thus, a smooth rotational and oscillatory motion can be achieved with superior anti-wear and load properties in each type. PILLOBALL Rod Ends have either a female thread in the body or a male thread on the body, so they can be easily assembled onto machines. They are used in control and link mechanisms in machine tools, textile machines, packaging machines, etc. The maintenance-free type is especially suitable for loading in one direction and is the best choice for machines in which oil must be avoided such as food processing machines, or machines which cannot be re-lubricated.
