Magnetic Cylinders from Rotary Technology utilize high-quality tool steel, high-strength permanent magnets, and glue with excellent quality and stability, to ensure Magnetic Cylinders’ accuracy and long-term durability.

Magnetic Cylinders are available for all commonly used rotary printing presses, including letterpress, flexo, rotary offset, and combination printing presses.

Cylinders can also be made to suit various types of rotary converting machines including form presses, envelopes, and special rotary die cut machines.

-Use “Bolted Bearer” design with Bearer's vacuum heat-treated to 60 - 62 Rockwell hardness, to ensure the cylinder’s excellent ware-resistance and durability;

-High-strength permanent magnets are selected and used to ensure superior magnetic strength. Special super-strong magnets are also available for small-sized cylinders and some other special applications;

-Each Magnetic Cylinder is supplied with Gear, precisely made as per OEM specifications. All Gears are treated with an anti-rust blackening process.

-High-strength glue is selected to eliminate any possibility of raised glue and raised magnets issues, which are commonly seen on some inferior Magnetic Cylinders used in hot and humid weather conditions;

-Concentricity / Roundness is guaranteed to be controlled within a 1-2 micron range across all cylinders, including Shaft, Bearer, and Body, to ensure long-term rotational accuracy;

-Industry-standard gap between Bearer and Body, to be controlled within 1 micron, to ensure Magnetic Cylinders from Rotary Technology can not only be suitable for its own Flexible Dies but also be compatible with Flexible Dies made by the world’s other prominent tool makers.
