DU Flange Bushings - The Difference Between Bushings and Bearings
Author:admin Date:2023-05-23
DU bushings are metal-polymer composite bearings that are self-lubricating. They have a steel base bonded to a porous sintered bronze interlayer that is impregnated with PTFE.
These DU Flange Bushings resist corrosion, reduce friction between rotating surfaces, and allow for low speed operation. They also feature low wear rate and are seizure resistant.
Straight Bushings
The difference between bushings and bearings can be confusing, especially when you’re looking for the right part for your project. While it’s true that bushings and bearings both work to provide low-friction motion, there are several differences between the two that make them ideal for different projects.
Among these differences, the most significant is that bushings are designed to be self-lubricating. This means that they can be used for linear, oscillating, and rotating movements. In addition, they can handle a wide range of load capacities and temperatures.
Additionally, DU bushings are also resistant to corrosion, making them the ideal choice for use in automotive, industrial machinery, and heavy equipment industries. These benefits make DU bushings a cost-effective solution for improving the performance, durability, and longevity of your machine. They can help to reduce noise, vibration, and energy usage while also reducing the amount of wear and tear that your machine experiences. With these benefits, it’s no wonder that DU bushings are the preferred choice of many mechanical engineers.
Thrust Washers
Thrust washers are flat disk-shaped bearings that can be made from either metal-polymer or fiber reinforced composite materials. They share many of the same properties as our straight bushings, including excellent wear resistance and a low coefficient of friction.
Because of this, they can be used to support axial loads in rotary applications that require a thrust surface. They are commonly found in a number of different mechanical hardware components, from appliances to power tools and vehicles.
Unlike traditional washers, which are designed to restrain displacement and reduce friction between machine elements by spreading the load over a greater surface area, thrust washers work by absorbing or transmitting the load through a series of shallow, scraped pockets. This allows them to distribute the axial load evenly and reduce friction between components. This design feature can significantly reduce maintenance requirements and costs, while providing a more robust solution to friction-related problems. This is particularly important for ePowertrain, hybrid and EV powertrain systems that operate at high temperatures and demand high-performance components.
Block Bushings
A block bushing is a bearing that restricts rotation and movement while maintaining proper alignment. It requires lubrication to minimize friction, but it doesn’t have to be re-lubricated each time you use it. This is because some pillow-block bushings are designed with a porous sleeve that absorbs and releases lubricant gradually over time. These are known as self-lubricating pillow block bushings.
Linear bushings use linear motion to achieve smooth, precise movements in applications like semiconductor manufacturing equipment and transportation systems. Most of the time you see these bushings in sets (for example, at the corners of a linear motion unit) because single bushings have almost no moment load capacity.
Split Double Flanged Bushings
Bushings, also known as plain or sleeve bearings, reduce friction between two parts by allowing the surfaces to move in a sliding motion. They may be made from a variety of materials, including metal, plastic or ceramics. However, the design of the bushing is what determines its capability. A part designer should always begin with a clear understanding of what the fastener needs to be capable of doing.
Our split double flanged bushings feature a compensation gap that collapses to provide easy installation. They are positioned over the mounting hole with the flange facing upward, and light finger pressure spirals the bushing into place.
The bushing is composed of a composite material consisting of 3 bonded layers; Steel backing bonded with porous sintered bronze interlayer that is impregnated and overlaid with polytetrafluoroethylene (PTFE). The resulting self-lubricating bushing exhibits low static and dynamic load capacity, good wear resistance and can be used in heavy duty unlubricated applications.
