Guideways PM

TM series is another model of miniature linear guideways by Hiwin company. Its main advantage is the small size and reduced weight by 20%, that makes possible to use the guideway in miniature equipment. The rail guideways of PM series are made of stainless steel including  the balls and retainer that provides excellent corrosion resistance and extends the service life. The integrated design of the balls rotation system provides a low noise level, caused by the balls collision. The profile guideways of PM series can be applied in many directions such as the semiconductor industry, installing printed circuit boards, medical equipment, robotics, measuring devices, office automation, etc.

Accuracy classes

Accuracy classes of PM series are classified into:

  • - normal (C),
  • - high (H),
  • - precision (P).

The choice depends on the equipment requirements.

Standard and maximum rail length

 

Hiwin offers a standard rail length to the needs of the client. For non-standard length E recommended size should not exceed 1/2 of the pitch (P). It prevents the instability of the rail end.

 

 

L=(n-1)*P+2*E

L - total length of guideway (mm) 
n - number of mounting holes
P - distance between the two holes (mm)
E - distance from the center of the last hole to edge (mm)

 

Standard and maximum guideway length.
