Oil-free bushing housing units are mechanical components used in machinery to provide support and reduce friction between two moving parts. These units typically consist of a bushing, a housing, and a locking mechanism to secure the bushing in place.
Oilless bearings are manufactured from a material that incorporates its own lubrication in the form of powdered graphite.

Oil-Free Bushing Housing Units – Standard Flanged – Standard – Built-In Copper Alloy Bushings
Oil-free bushing housing units are a type of bearing assembly designed to operate without the need for oil-based lubrication. These units provide a low-maintenance and environmentally friendly solution for applications where traditional lubricants may not be suitable or desired. They are commonly used in industries such as food processing, pharmaceuticals, and cleanroom environments, where contamination from the oil can cause problems.

Bushing Material: Oil-free bushings are typically made from self-lubricating materials like polytetrafluoroethylene (PTFE), graphite, or other composite materials with a low friction coefficient. These materials eliminate the need for oil-based lubrication and minimize wear on the moving parts.
Housing: The housing is the external structure that supports and protects the bushing. It is generally made of corrosion-resistant materials such as stainless steel, aluminum, or engineering plastics, which offer durability and stability.
Shaft: The shaft is the rotating component supported by the bushing. It is typically made of materials that are compatible with the bushing material to minimize friction and wear. Examples include stainless steel, chrome-plated steel, or hard-anodized aluminum.
