varuosa

Varuosa is the Estonian term for a spare part or replacement component used to repair or maintain equipment, vehicles, or machinery. A varuosa is any part kept in inventory to substitute a failed or worn component, enabling repairs without complete replacement of the device. Common examples include filters, seals, bearings, electronic modules, and fasteners. The term is widely used in maintenance, manufacturing, automotive service, and electronics repair, and appears in service manuals, parts catalogs, and service agreements.

In practice, managing varuosa involves identifying the exact part by model and serial numbers, ensuring compatibility, and sourcing from original equipment manufacturers (OEM) or aftermarket suppliers. Inventory planning emphasizes minimizing downtime and balancing cost, lead time, and stock holding. Varuosa can be categorized as standard, critical, or obsolescent, depending on availability and criticality to operation.

Etymology: The word is a standard Estonian noun, formed as a compound that conveys the concept of a spare or substitute part. See also spare part, replacement component, and maintenance inventory.
