Idler is designed for support of rotary cement kiln drum.

Idler consists of two supporting blocks and common frame. Supporting block consists of supporting idler pressed on the shaft to be installed on two bearing units equipped with rolling bearings.

Rolling bearings take up the radial load and part of axial one. One of the support idler trunnions in assembly with shaft axially is fixed in bearing housing by means of thrust bearings. Bearings lubrication is liquid, circulating lubrication is performed by means of individual lubrication system. It is allowed to use lubrication from centralized lubrication system or grease embedded lubrication. Idlers cooling is water closed-circuit.
