Structure of the product:

1. Lined Joinbal: self-alignment is guaranteed between the outer diameter surface of the spherical inner ring and the spherical inner diameter surface of the liner; a proper clearance exists in between as a lubricant reservoir.

2. PTFE Lined Joinbal: PTFE liner made of reinforced poly tetra fluoro ethylene resin is used in the metal housing. As a kind of solid lubricant, the liner guarantees self-alignment between housing and outer diameter of the spherical inner ring.
