Several important parameters need to be known when selecting a guide rod cylinder

The cylinder with guide rod is a cylinder with guiding function. When selecting, it is different from ordinary cylinders. You cannot simply select according to the cylinder theory table. So how should you select? What are the important parameters of a cylinder with guide rod?

Cylinder with guide rod Selection parameters of cylinder with guide rod:


Non-rotating accuracy: At the retracted end, the non-rotating accuracy when there is no load should be below the value in the table below.





Eccentric load: The load does not act directly on the end plate, but produces an eccentric load, which actually produces a certain torque force on the guide rod.

Two installation postures: vertical installation and horizontal installation

Two configurations: sliding bearings and rolling bearings








Selection sequence of cylinder with guide rod:

1. Confirm the installation method: vertical installation or horizontal installation.

2. Preliminary selection based on comprehensive data: Select the appropriate guide cylinder based on load weight, stroke size, and lookup tables.

3. Whether the accuracy meets the standard: Check whether the cylinder accuracy meets our process requirements.

4. Determine bearings according to needs: Choose sliding bearings or rolling bearings according to the actual service life of the equipment.

Different selection systems for cylinders with guide rods: The installation method is an important parameter for selection. We will take an example from each of vertical installation and horizontal installation to illustrate the different selection systems.

Vertical installation:

Bearing selection: ball bearings

Stroke: 30mm

Maximum speed: 200mm/s

Load mass: 3kg

Eccentricity distance: 90mm

It consists of vertical installation, ball bearing, 30mm stroke, speed 200mm/s

In the graph, find the intersection point where the load mass is 3kg and the eccentric distance is 90mm.








Horizontal installation:

Bearing selection: sliding bearings

Distance from end plate to load center of gravity: 50mm

Maximum speed: 200mm/s

Load mass: 2kg

Stroke: 30mm

Horizontal installation, sliding bearing, 50mm stroke to load, speed 200mm/s

In the graph, find the intersection point of the load mass 2kg and the stroke 30mm.








The selection of cylinders with guide rods is affected by high speed, eccentric load, load mass, and bearing factors. The selection system is different from that of ordinary cylinders.
