Holkilaakerit

Holkilaakerit, often translated as bush bearings or sleeve bearings, are a simple type of plain bearing. They consist of a cylindrical sleeve or bush that provides a low-friction surface for a rotating or sliding shaft. Unlike rolling-element bearings, which use balls or rollers to reduce friction, holkilaakerit rely on sliding contact between the shaft and the bearing surface.

These bearings are known for their robustness and ability to withstand high loads and shock conditions. They are often made from materials like bronze, brass, or various polymers, chosen for their self-lubricating properties or compatibility with external lubrication. The design is straightforward, making them cost-effective for many applications.

Holkilaakerit are widely used in a diverse range of industries. They can be found in automotive components such as steering systems and suspension parts, in industrial machinery like pumps and gears, and in everyday items such as hinges and furniture. Their simplicity and reliability make them a popular choice where space and cost are significant considerations. Maintenance typically involves ensuring adequate lubrication, either through integrated systems or regular application, to prevent wear and maintain performance.
