Rullalaakereita
Rullalaakereita is the Finnish term for rolling bearings, a family of bearing assemblies that reduce friction between moving parts by placing rolling elements between inner and outer races. They are designed to support radial loads and, in many configurations, axial loads as well, enabling smooth rotation in machinery and vehicles.
Construction and variants: typical rolling bearings consist of an inner race, an outer race, rolling elements
Materials and lubrication: most bearings are made from high-strength alloy steels or surface-treated variants; surfaces are
Applications and reliability: rolling bearings are ubiquitous in automotive drivetrains, industrial gearboxes, electric motors, machinery, aerospace
