I produced the roller type of roller groups, wide range of use, quality excellence. There are various types of groove type, all kinds of parallel supporting roller group, all kinds of the roller group of the heart roller group. Its size can meet all kinds of belt machine installation requirements, special circumstances can specify the order. Trough type roller ordinary type, forward type, quick change bearing type, hanging type, variable angle groove type, transitional type, steel type, spiral, etc.; self-aligning roller has the universal, friction type reversible, strong, cone type, spiral type combined type, etc.; buffer roller spring plate, buffer ring, strong buffer type, adjustable elastic type, hanging type. The structure of all kinds of rollers is advanced, the performance is reliable, and the material of roll skin is strictly selected. The quality welding is adopted, and there is strict tolerance.. The shaft material is cold drawn round steel, bearing by using high-quality steel stamping. Dust, earthquake resistance are better than the relevant national standards. After the assembly, the dry strength of the roller is good, the lateral beat is best, the rotation resistance is small, the energy consumption is low, and the service life is long.
