Understanding Oil Free Bushings Housing Units

What is Bushing Housing?

A bushing housing, also known as a bearing housing or pillow block, is a protective enclosure that houses a bushing or bearing. The primary function of the housing is to provide support, stability, and proper alignment to the bushing, allowing it to function efficiently within the machinery.

The bushing housing acts as a secure mount for the bushing, preventing any misalignment or movement during operation. It provides a stable platform for the bushing to rotate or slide, minimizing friction and wear. The housing also helps distribute the load and forces exerted on the bushing, enhancing the overall performance and longevity of the equipment.

Components of Oil Free Bushings Housing Units

Bushing Material: Oil-free bushings are designed to work without traditional lubricants. They are typically made from self-lubricating materials like polytetrafluoroethylene (PTFE), graphite, or other composite materials with a low friction coefficient. These materials have inherent lubricating properties, which eliminate the need for oil-based lubrication and reduce wear on the moving parts.

Housing: The housing is the external structure that encloses and supports the bushing. It plays a crucial role in maintaining the position and alignment of the bushing within the system. The housing is generally constructed from corrosion-resistant materials such as stainless steel, aluminum, or engineering plastics. These materials provide durability, stability, and protection against harsh environmental conditions.

Shaft: The shaft is the central component that rotates within the bushing. It relies on the bushing’s low-friction properties to facilitate smooth rotation. The shaft is usually made of materials that are compatible with the bushing material to further reduce friction and wear. Common materials for shafts include stainless steel, chrome-plated steel, or hard-anodized aluminum.

Enhanced Features of Oil-Free Bushings

In this product overview, we introduce the latest advancements in our economy series of oil-free bushings. With a technical upgrade, the case material has been transitioned from stainless steel to a more efficient aluminum alloy. Additionally, the oilless bushing material has been improved, now made of a high-quality bronze alloy.

One notable enhancement is that the oilless bushing is no longer simply embedded in a hole; instead, it is seamlessly integrated as one piece. This modification ensures a more even distribution of solid lubricant, leading to improved lubrication performance and a remarkable reduction in noise levels.

Moreover, our product is particularly recommended for applications involving vertical motion due to its easy installation and low maintenance frequency.

Key Features of the Oil-Free Bushings:

Advanced Integration: We have integrated the oilless bushing into a copper plate using a robust adhesive, enabling a tight press-fit between the bushing and the aluminum alloy case. This innovation significantly improves the distribution of solid lubricant, resulting in a 20% increase in the lubricating area and a much-improved lubrication effect for the oil-free bushing.

Extended Service Life: Our new and improved design ensures a longer service life for the bushings. In a comparative test under specific conditions, the conventional type exhibited a final wear amount of 0.030 mm, while our new product demonstrated a significantly reduced wear amount of 0.020 mm. These conditions involved a surface pressure of 25 N/mm2, a swing speed of 1 m/min, a swing frequency of 96,000 times, and an experiment duration of 100 h.

With these upgrades, our oil-free bushings deliver exceptional performance, making them an ideal choice for a wide range of applications. Experience the benefits of improved lubrication and noise reduction with our innovative oil-free bushings.
