csúszócsapágyaknál

Csúszócsapágyaknál, often translated as plain bearings or sleeve bearings, are a type of bearing that relies on sliding motion between surfaces. Unlike rolling-element bearings which use balls or rollers to reduce friction, csúszócsapágyaknál achieve low friction through the use of a lubricant between the stationary and rotating or sliding parts. These bearings are characterized by their simplicity in design and their ability to support heavy loads, often with excellent shock absorption capabilities.

The primary function of a csúszócsapágy is to constrain relative motion between machine parts and reduce friction. They are typically composed of a shaft and a housing, with the space between them filled with a lubricant. This lubricant can be oil, grease, or even a solid lubricant like graphite or MoS2. The lubricant forms a thin film that separates the surfaces, preventing direct metal-to-metal contact and thus minimizing wear and heat generation.

Csúszócsapágyaknál find application in a wide range of industries due to their reliability and cost-effectiveness. They are commonly used in engines, pumps, hinges, and many other mechanical systems where smooth, low-friction movement is required. Their robust nature allows them to operate effectively in harsh environments, including those with high temperatures, high pressures, or the presence of contaminants. The material of the bearing surface is crucial and is often made from bronze, polymers, or specialized alloys to enhance durability and performance under specific operating conditions.
