The diameter series of the reversing drum are: 250, 315, 400, 500, 630, 800, 1000, 1250, 1400, 1600, 1800mm.

● The drum surface is available in three options: steel smooth, cast rubber smooth, and magnet-free stainless steel smooth.

● Depending on the drum's load-bearing capacity, there are two types of drum structures: steel plate welding and cast welding. The drum body and flange of the cast welding drum have both undergone strength verification using the finite element method.

The bearing housing of the drum is divided into two main types: integral and split. Both types can be equipped with ordinary spherical roller (pill) bearings and spherical roller (pill) bearings with retaining sleeves. The manufacturers of the bearings can be well-known domestic brands like Harbin, Wa, Luo, or international brands such as SKF, FAG, etc., as selected by the owner.

All drums have undergone static balancing inspection; drums of large specifications as stipulated by national standards are dispatched after undergoing annealing and flaw detection tests.
