What is Aluminum Pneumatic Cylinder tubing?

Aluminum Cylinder Tube (also known as aluminum Cylinder Barrel) is a type of irregular tube used for assembling cylinders, with smooth honing of the inner wall and high accuracy.

It only needs to be cut, flattened, tapped, and deburred according to the actual required length, and can be assembled with the front and rear bases of the cylinder. Most aluminum cylinder tubes are made of 6063 aluminum.

Greatly improving production efficiency and product qualification rate, greatly reducing production and processing costs. Each type of cylinder has a corresponding cylinder tube, cylinder installation positioning hole, magnetic spring switch fixing groove, cylinder inner diameter, outer diameter, etc., all of which are completed in advance on the cylinder tube.

Product category

Round cylinder pipes, square cylinder pipes, Mickey Mouse style cylinder pipes, compact cylinder pipes such as SDA, CQ2, ADVU, double rod cylinder and compact guide cylinder pipes, stainless steel honing hydraulic pipes, etc.

Characteristics of different types of cylinder pipes

Rotundity

Generally used for SC series rod cylinders and aluminum alloy small cylinders. It has a simple structure, low cost, and convenient installation. The inventory is large, so we can ship quickly for most types. The maximum inner diameter is 320 millimeters.

Square type

Mainly used for DNC series and ISO series cylinders. A square cylindrical tube is much stronger and has more accurate dimensions than a regular circular cylindrical tube. After oxidation treatment on the inner wall and honing, the surface is smooth and wear-resistant. It can match most ISO15552 and ISO6431 cylinder front and rear bases.

The installation thread can be directly processed on a square cylindrical pipe without the need for another pull rod to fix it. In addition, there is an installation groove for the magnetic spring switch on the cylindrical tube, which can be directly fixed on the cylindrical tube without any support. The operation is very simple. The aperture range is from 32mm to 125mm.

Mickey Mouse style cylindrical tube

The cross-section of the Mickey Mouse cylindrical tube is similar to that of Mickey Mouse, so it is commonly referred to as the Mickey Mouse cylinder, used for assembling SI, SU, and ISO series cylinders. The characteristic of this oil cylinder pipe is to use four raised ribs to replace the tie rod on the tie rod oil cylinder. In this way, it can greatly reduce the problem of uneven installation force and is much more convenient to assemble than SC cylinders.

The cost of Mickey Mouse shaped cylindrical tube is between SC circular cylindrical tube and DNC square cylindrical tube, and its strength is much stronger than SC type. The aperture (inner diameter) range is 32mm to 320mm. Please note that although the Mickey Mouse style cylindrical tubes of the SI and SU series look the same in appearance, there are slight differences in the specific installation dimensions and cannot be replaced arbitrarily to avoid problems during assembly.

SDA, CQ2, and other compact cylindrical tubes

Compact cylinders are special. Their front and rear covers or bases are fixed with snap rings, unlike other cylinders that are fixed with threads or pull rods. The aperture range is usually 32mm to 100mm.

Double rod oil cylinder tube and compact guide oil cylinder tube

The biggest advantage of a double link oil cylinder is that it can ensure the parallel movement of the cylinder piston without any rotation or oscillation. Common double link cylinder pipes include TN, CXS, MGP series, etc.
