Are Round Flanged Oilless Bushing suitable for high-temperature applications?
Round flanged oilless bushings, often made of materials like bronze, are generally suitable for a range of applications, including those involving moderate temperatures. However, the suitability for high-temperature applications depends on the specific material composition and design of the bushing.
Bronze bushings, for example, are known for their good heat resistance and can handle relatively high temperatures. However, it’s crucial to check the specifications and recommendations for the particular bushing you’re considering. High-temperature applications may require specialized materials, such as heat-resistant alloys, to ensure optimal performance and longevity.

Half Graphite Plugged Bronze bush Bearing With Collar
Half graphite plugged bronze bush bearings, also called Split type bush Bearings, in essence, are self-lubricating components designed to reduce friction and wear in machinery. The unique composition of graphite and bronze imparts enhanced durability and performance to these bearings. The half design ensures efficient lubrication while maintaining structural integrity. The benefits of using these bearings extend beyond conventional options, making them a standout choice in the engineering realm.
Collar in Bearings: What Sets It Apart?
What distinguishes these bearings is the incorporation of a collar. The collar acts as a stabilizing feature, providing additional support and preventing misalignment. This is particularly advantageous in applications where precise alignment is crucial for optimal performance. The collar sets these bearings apart, contributing to their reliability and longevity.
