Introduction:
It is equipped with high-quality rubber liner and quick gas filling and discharging nozzle, which has good sealing effect, long service life, removable shaft head and convenient maintenance.
After inflation, the unilateral expansion height can reach 5mm to 6mm. For example, the diameter before inflation is 74mm to 75mm, and the diameter after inflation can reach 79mm to 82mm. Special expansion height is required separately.
The 3-inch key type air expansion shaft usually uses a roll tube with an inner diameter of 76mm. The convex key type air expansion shaft expands a single key strip, and the fulcrum spreads to each key strip to balance the force. It can be used for mechanical reeling of heavy load bearing items, such as cloth, paper, film, printed goods, leather, composite materials, etc. It can be used for reeling and unwinding of related machinery such as coating, slitting, printing, rewinding, compounding, papermaking, bag making, plastic, etc It can effectively improve work efficiency.
