siklócsapágyak

Siklócsapágyak, also known as plain bearings or journal bearings, are a type of bearing that uses a sliding surface rather than rolling elements. They are characterized by their simplicity and ability to support loads in any direction. The basic principle involves two surfaces in relative motion, with one surface sliding directly against the other. To reduce friction and wear, a lubricant is typically introduced between these surfaces.

The construction of a siklócsapágy is generally straightforward. It consists of a stationary housing and a rotating shaft, or vice versa. The bearing surface itself can be made from various materials, including bronze, brass, plastics, and composite materials, chosen based on factors like load capacity, speed, temperature, and the presence of contaminants. The lubricant, which can be oil, grease, or even a solid lubricant like graphite, forms a film that separates the sliding surfaces, preventing direct metal-to-metal contact.

Siklócsapágyak are widely used in numerous applications due to their low cost, high load capacity, and quiet operation. They are found in automotive components such as crankshafts and camshafts, in industrial machinery like pumps and electric motors, and in simpler devices like hinges and drawer slides. Their primary advantage lies in their ability to handle shock loads and vibrations effectively. However, they can be susceptible to wear if lubrication fails or if abrasive particles are present. Maintenance often involves ensuring proper lubrication levels and monitoring for signs of wear.
