A Metric Self-Lubricating Bush Glide Metal Maintenance-Free refers to a bushing that is designed for metric-sized applications, incorporates self-lubricating properties, and requires minimal to no maintenance.
The bush glide is made of metal, often a high-quality alloy such as bronze or stainless steel, which provides excellent wear resistance and durability. The self-lubricating feature means that the bush glide is able to maintain smooth operation without the need for regular lubrication, significantly reducing maintenance requirements.
The metric sizing ensures compatibility with standard measurement units, making it easy to integrate into various mechanical systems. This bush glide is designed to provide a low-friction interface between moving parts, allowing for smooth gliding motion with reduced wear and tear.
Overall, a Metric Self-Lubricating Bush Glide Metal Maintenance-Free offers a reliable and efficient solution for metric-sized applications where reduced maintenance and improved performance are desired. It is commonly used in various industries, including automotive, machinery, and industrial equipment, to enhance the operational efficiency and lifespan of mechanical systems.

Graphite plugged brass bushing is a type of solid metal bearing. This type of self-lubricating bearing is also called #500 oilless bearing,brass bearing, cooper bushing, solid sliding bearing, guide bushing, and graphite filled bearing.
An oilless sliding bearing which shows its great effectiveness in places which are diffi cult to oil, or where the lubricating effect cannot be maintained. With a high-strength brass base and embedded solid lubricant, it is an oilless type which can be used in places with a high load.
