Maintenance; Specific Product Precautions - SMC Networks CYP Series Technical Data Manual

Caution
1. Never disassemble the cylinder tube or linear guide,
etc.
If disassembled, the slide table may touch the outside surface
of the cylinder tube resulting in a degradation of particulate
generation characteristics.
2. Cylinder maintenance should be performed roughly
at the operating cycle of 500 thousand or operating
distance of 400 km.

Maintenance

Particulate Generation Characteristics
Caution
1. In order to maintain the particulate generation
grade, use operation of 500 thousand cycles or
travel distance of about 400 km as a standard.
(Graph (1) below)
If operation is continued beyond the recommended values,
lubrication failure of the linear guide and loss of particulate
generation characteristics may occur.

Particle diameter (μm)
Note 1) This chart indicates the level of cleanliness inside the
measurement chamber.
Note 2) The vertical axis shows the number of particles per unit
3
volume (1 m ) of air which are no smaller than the
particle size shown on the horizontal axis.
Note 3) The gray lines show the upper concentration limit of the
cleanliness class based on Fed. Std. 209E-1992.
Note 4) The plots indicate the 95% upper reliability limit value for
time series data up to 500 thousand operation cycles.
(Cylinder: CYP32-200, Workpiece weight: 5 kg, Average
speed: 200 mm/s)
Note 5) The data above provides a guide for selection but is not
guaranteed.
2. When the amount of grease at the linear guide is
insufficient depending on the operating conditions,
regular application of grease is recommended.
In such cases, the amount of dust may temporarily increase.
After operating the cylinder for a short period of time,
increased dust gradually decreases.
