Roller brushes with plastic cores are defined as having a core length of 100 mm or more. In this case, HK demonstrates its broad approach in the range of sizes, core materials and bristle types it offers.
Roller brushes with plastic cores are available with a centre hole or continuous steel or stainless steel shaft
Roller brushes with tubular steel cores are defined as having a core length of 100 mm or more. The basic core, consisting of steel or stainless steel (1.4301, 1.4541) considerably improves the strength of the brushes. The bristles are secured in a steel strip mount which is attached to the roller core in the form of a coil.
The bristle density of roller brushes can be influenced by the method of attachment of the steel strip mount. Spiral brush systems can also be made without basic cores. By means of a special steel strip mount (concave backed strip), the coils are welded together to form a compact brush package.
