Lug Shaft

The lug key air expansion shaft, the key air expansion shaft, the claw air expansion shaft, the claw key air expansion shaft, the convex key type air expansion shaft main body is made of high quality steel pipe, the surface is chrome-plated, the aluminum convex key is flexible and flexible; Bile and fast filling and exhausting nozzle, good sealing effect, long service life, detachable shaft head, easy maintenance. After inflation, the unilateral expansion height can reach 5mm to 6mm.

For example, the diameter before expansion is 74mm to 75mm, and the diameter after expansion can reach 79mm to 82mm. The special expansion height is separately required. 3 inch key type air expansion shaft, usually using the inner diameter of the coil tube 76mm, the convex key type air expansion shaft expands from a single key strip, the fulcrum spreads to each key strip, balances the force, and can be applied to the mechanical winding capacity. Items, such as cloth, paper, film, printed matter, leather, composite materials, etc., suitable for coating, slitting, printing, rewinding, compounding, paper making, bag making, plastics, etc. Improve work efficiency.

Convex/lug type air shaft specification
There are a variety of, including 1 inch, 1.5 inch, 2 inch, 2.5 inch, 3 inch, 6 inch, 8 inch, 10 inch, 12 inch, etc., according to demand can be processed to produce different specifications of the expansion shaft. The male-type air-expansion shafts are generally made according to the needs of practical applications. There are no standard items, and different types are selected according to actual needs. Common types include aluminum alloy air expansion shaft, expansion key type air expansion shaft and blade type air expansion shaft, and some distinguish between metal and non-metal. The inflation shaft is generally designed by the user and supplied to the manufacturer of the inflation shaft. At the same time, the ordering requirements must be attached, such as the weight of the inflation shaft, the material and its accuracy requirements. The manufacturer will perform technical evaluation based on the drawings and other requirements provided by the user before production.

Technique parameter

The main body of the convex-key type air-expansion shaft is generally made of high-quality steel pipe, the surface is chrome-plated, and the aluminum convex key is flexible and flexible. Secondly, it is equipped with a high-quality rubber liner and a fast filling and exhausting nozzle, which has good sealing effect and long service life. The detachable shaft head improves the convenience of the later maintenance, shortens the maintenance time, and avoids the impact on the production of the enterprise. In addition, since the convex key type gas expansion shaft is expanded by a single key strip, the fulcrum is diffused to each key strip. The force is more uniform, which further improves its performance. At present, it has been widely used in many industries, bringing convenience to people's work.
