Bronze Gleitlager – Things To Know
Bronze-gleitlager, often referred to as bronze plain bearings or bushings, are mechanical components designed to provide a surface for rotary or sliding motion between two parts of a machine, reducing friction and wear. The addition of graphite (“mit Grafite”) enhances their self-lubricating properties, making them suitable for applications where maintenance and lubrication are difficult.
Bronze Gleitlager: The right solution for every application
Bronze bearings infused with graphite offer exceptional load-bearing capacity, durability, and outstanding self-lubricating properties. The bronze base provides resistance to corrosion and wear, while the embedded graphite acts as a dry lubricant, minimizing friction and wear even in challenging operational environments. These bearings excel in high-load, low-speed settings and can function under oscillating or intermittent motion. They are particularly effective in dirty or corrosive conditions where traditional lubricants may falter.
Over time, the demands for bearings have grown more stringent, leading to the development of various oil-free bearing variants crafted from diverse materials. Our product range encompasses a variety of oil-free bushes, spanning from standard graphite-plugged bronze bushings to custom-sized options. In essence, we offer the ideal plain bearing solution tailored to every application.
