Expansion sleeve

Structure and application of air expanding sleeve clamp

The inflatable sleeve clamp or "inflatable sleeve" is mainly composed of front sleeve, back sleeve, cylinder, inner tube, air bag, convex keyboard and other parts. It is suitable for coating, printing, rewinding, papermaking, plastic and other related machinery. Especially in the three or six inch gas expansion shaft frequent use of light load occasions, it shows its superiority.

The material of the air expansion clamp is made of high-quality aluminum, and the surface is oxidized. Equipped with high quality air bag and fast inflation nozzle. Good sealing effect, long service life and convenient maintenance. The outer diameter of the main body of the air expansion sleeve clamp is Φ 150 mm, the action outer diameter is Φ 155 mm, the applicable paper tube is Φ 152.4 ± 0.2 mm, and the main body length is 250 mm. It can replace the six inch gas expansion shaft by installing two gas expansion sleeve clamps, which is light in weight and easy to install and replace.

Inflatable drum and inflatable sleeve

Overview of character

1. Purpose: set on the outside of 3-inch air expansion shaft to achieve 6-inch effect

2. After inflation, it is equivalent to a 6-inch inflatable shaft with an outer diameter of? 155-158mm

3. High quality aluminum alloy hard oxidation treatment (surface Brown), light and convenient to use
