High Performance Plastic Bushing

TL bushings are widely recognized across the world for their superior anti-seizure and frictional characteristics, as well as their capacity to handle heavy loads. For applications needing long lubrication gaps, the industry also favors TL bushings.

Our designed bushings' outstanding serviceability for high-load/low rotating speed applications is the result of three variables working together. These elements are:

1. Selection of the right steel and heat treatment
2. Surface treatments with patents
3. ID cross-hatching and surface cavities are two patented surface elevations.

A system of grooves on the bushing's inner surface is used for cross-hatching. A grease reservoir is created in the connecting channels of a lubricated joint, increasing lubrication intervals by up to 100%. In many industrial settings, debris that is present in the contact zone frequently exhibits extremely high hardness, which causes early joint wear. Effective evacuation of undesired particles and trash is made possible by cross-hatching.

Surface cavities act as a lubricant reserve, enabling exceptionally extended lubrication intervals or maintenance-free operation of the joint. At the contact sites, grease is held rather than being ejected. Surface cavities enable the development of a local hydrodynamic friction mode at high sliding speeds; the contact pressure is then supported by the nearby grease bearings.
