Rodless Magnetic Coupling Guide Pneumatic Air Cylinder

Short Description:

Pneumatic cylinders (sometimes known as air cylinders) are mechanical devices which use the power of compressed gas to produce a force in a reciprocating linear motion.

Like hydraulic cylinders, something forces a piston to move in the desired direction.  The piston is a disc or cylinder, and the piston rod transfers the force it develops to the object to be moved.  Engineers sometimes prefer to use pneumatic because they are quieter, cleaner, and do not require large amounts of space for fluid storage.

Because the operating fluid is a gas, leakage from a pneumatic cylinder will not drip out and contaminate the surroundings, making pneumatic more desirable where cleanliness is a requirement.  For example, in the mechanical puppets of the Disney Tiki Room, pneumatic are used to prevent fluid from dripping onto people below the puppets.

Note:

1. Within allowable stroke scope,when the stroke is large than the maximum value,it shall be treated as non-standard one.  Please contact the company for other special strokes.

2. The non-standard stroke of the scope of maximum stroke is transformed according to the standard stroke of the upper grade and its shape and dimension are equal to that of standard stroke cylinder of the upper grade. For instance, the non-standard stroke cylinder whose stroke is 23 is transformed from the standard cylinder whose standard stroke is 25,and their shape and dimension are the same.

Characteristics:

◆ Rodless cylinders with magnetic coupling have no piston rod protruding from the cylinder block

◆ The overall installation size is small, and the axial space is small, which saves about 44% of the axial space than the standard regular cylinders.

◆ The piston area at both ends of the magnetic coupling rodless cylinder is equal, so the values of the thrust and the pulling force are equal, and it is easy to achieve intermediate positioning. When the piston speed is 250mm/s, the positioning accuracy can reach ±1.0mm

◆ The surface of the piston rod of standard regular cylinder is easy to accumulate dust and rust, and the rod seal may absorb dust and impurities, resulting in leakage. However, the external slider of magnetic coupler rodless cylinder has no dynamic seal and no external leakage.

◆ Magnetically coupled rodless cylinder can produce ultra-long stroke specifications. The ratio of the inner diameter to the stroke of the standard regular cylinder is generally not more than 1/15.

◆ While the ratio of the inner diameter to the stroke of the rodless cylinder can reach about 1/100, and the longest stroke can be produced to 3m within the range to meet the needs of long-stroke applications.

◆ The magnetic coupling type has a small shape and has mounting threads and nuts at both ends, which can be directly installed on the equipment

◆ The magnetic coupling rodless cylinder has a relatively small load and is suitable for loading small workpieces or manipulators to move

◆ When the basic magnetic coupling type moves back and forth, the slider may rotate, and a guide rod guide device must be added, or the magnetic coupling rodless cylinder with a guide rod type is selected.

◆ Compared with the mechanical type of the guide belt part of the leakage defect, magnetically coupled rodless cylinder has no external leakage, and can be maintenance-free after installation and use.
