Bushes and collars form an integral part of industrial or workplace power transmission systems. They help to enhance precision movement, and to reduce wear and tear on mechanical components, by limiting friction and axial slide (respectively) between key moving parts.
Bushes are available in various formats, for performing subtly but importantly different roles, and broad compatibility with a range of different machine parts.
A mechanical bush or bushing is a type of bearing or sleeving insert that’s placed into a housing between two (usually moving, often rotary) parts.
A mechanical collar is more concerned with the latter role, i.e. helping to restrain movement and enhance precision interplay between two or more moving machine parts.
