The Surface Cooling Roller results in varying effects in different type of Cooling Rolls. Rotary Cooling Roller has a shaft with inside hole to fix rotary joint. Bigger shaft diameter is recommended to avoid breakage of end shafts as end shaft having inside hole and uneven alignment or heavy tension on shaft result brakeage so bigger shaft diameter is recommended. We are called upon as one of the major Industrial Cooling Roller Manufacturers in Gujarat(india).
For hot laminating rollers (up to 220oC), we would recommend using a high-release silicone compound, as this compound is capable of withstanding such temperatures & non sticky properties.
For hot lamination rollers, where temperatures will not exceed 150oC (and high load, abrasion and wear are considerations), then we would recommend using a synthetic rubber compound. These could include Hypalon, Carboxylated Nitrile and EPDM.
