The Pneumatic Adapter Chuck (air chuck adapter), also known as air chuck, converting chuck, or shaft sleeve, allows you to easily convert diameters without replacing the entire air shaft (airshaft) or traditional shaft core. Simply install the adapter chuck on existing equipment to perfectly adapt to paper tubes or material rolls of different inner diameters.

Pneumatic adapter chucks are mainly divided into two types: lug type (key type, key tooth type) and plate type, corresponding to models NED 36K300 (Key Type) and NED 36P300 (Plate Type). The common specification is for converting 3-inch to 6-inch, ensuring stable and non-slip clamping. Generally, two adapter chucks can be installed on a single shaft, effectively expanding the application range of your existing equipment.
