holkullinen

Holkullinen is a Finnish adjective used mainly in technical and engineering contexts to describe a component or feature that incorporates a sleeve or bushing, or is designed to accommodate one. The word is formed from the noun holkki, meaning sleeve or bushing, plus the common adjectival suffix -llinen, which denotes possession of a characteristic. In practice, holkullinen denotes parts that have a cylindrical sleeve or are intended to receive a sleeve or bore, such as a holkullinen laakeri or a holkullinen kiinnitys in industrial terminology.

In usage, holkullinen is most common in technical documentation, machine manuals, and product catalogs. It helps distinguish parts whose function relies on a sleeve or bearing insert from those without such a feature. The term often appears in compound nouns and phrases describing assemblies, joints, or fittings that employ sleeves to guide, align, or reduce wear between components.

Etymology and form: holkullinen derives from holkki (sleeve, bushing) with the adjectival suffix -llinen, a productive pattern in Finnish for forming descriptors of physical characteristics. The form agrees with the noun it modifies in number and case, producing phrases like holkullinen laakeri (sleeve-bearing bearing) or holkullinen kiinnitys (sleeve-type fastening) in common technical usage.

Holkullinen is relatively specialized vocabulary and is not commonly used in everyday language. It coexists with related terms such as holkki and laakeri, which describe the components themselves rather than their sleeve-bearing characteristic.
