Flange Cast Bronze Bushing

1 in stock

Many cast bronze bearings have flanges or shoulders as options. The flange is designed to aid in mounting and positioning. Flanges are also used with bearings on external housings. Flanged bearings are designed to handle both radial and thrust loads.

Description

Flange bronze bushing is commonly used to provide support for a shaft that runs perpendicular to the bearing’s mounting surface. Shafts can create problems when high speeds or heavy loads create shaft flex, vibration and axial load or movement. This can be eased with the application of a flange bearing that is located in such a way that it supports the shaft.

What are Cast Bronze Bushings?

A bushing, also known as a plain bearing, is designed to reduce friction between two surfaces as they slide against one another. In machines and equipment with rotating or sliding shafts, bushings are used to enhance overall efficiency and longevity while reducing noise and vibration. They generally come in the following two styles:

Sleeve bushings. Sleeve bushings are cylindrical in shape, featuring straight inside and outside diameters.
Flanged bushings. Flanged bushings feature a flange that extends radially outward from one end. The purpose of the flange is to act as a thrust face at one end of the bushing also preventing any axial movement.

As friction-reducing components, it is essential that bushings are constructed from wear-resistant materials that provide good sliding properties. While bushings can be fabricated from a variety of plastics and metals, bronze provides several distinct advantages over alternative options in heavy-load applications. As an inherently moldable and easy-to-machine material, bronze is well-suited for achieving a range of bushing designs.

The bronze alloy used in cast bronze bushings undergoes a continuous or centrifugal casting process, giving the metal a finer grain structure and improved mechanical properties. The bronze alloy cast bar is then cut and processed into the finished bushing using a computer numerical control (CNC) lathe or other precision machining method. Cast bronze bushings exhibit excellent structural strength, durability, and resistance to compressive forces, making them well-suited for harsh, high-wear applications. They can also withstand high temperatures without losing their strength.
