IKO Bearing PB8 Spherical Bushing Pilloball, Insert Type/ Lubrication Type , High Carbon Steel

Pilloballs are compact self-aligning spherical bushings that can support a large radial load and a bi-directional axial load at the same time. These bushings are classified by sliding surface types, namely, insert type, die-cast type and maintenance-free type. In the insert type, a spherical inner ring makes contact with the 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 the special PTFE liner of maintenance-free type. Thus, a smooth rotational and oscillatory motion can be achieved with superior anti-wear and loading properties in each type. PILLOBALL Rod Ends have either a female thread in the body or a male thread on the body, and they can be easily assembled onto machines. Pilloballs 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 machine. Or machines which cannot be re-lubricated.
