Linear bearings and ball screws by MPS Microsystems

MPS Microsystems

Located in Bienne Switzerland since the establishment of RMB in 1936, this MPS unit is now called MPS Microsystems. With nearly 150 employees on this site and sophisticated and fully customized facilities over 50,000 Sq’, MPS Microsystems offers its employees an exceptional working environment and provides customers with unique capabilities that are perfectly suited to the requirements of the medical and high-tech sectors.

Bearings & Ball Screws

MPS specializes in miniature high precision linear bearings with tolerances of diameter under the balls < 8 µm. The MPS ball screws are entirely made out of stainless steel and all components are ground. They are fitted with a double nut to adjust the play.

Linear Bearings DBL-Type

 

This comprehensive range of miniature precision linear bearings of a unique design offers considerable cost savings to our customers.

The segments of the housing are made of plastic (POM) and the outer diameter of the bearing is set by needles made of stainless steel which simultaneously operate as runways for the balls.

  • Cost-effective
  • Bore diameters from Ø 3 mm to Ø 25 mm
  • Excellent constancy in the performances when submitted to severe temperature variations

 

Linear Bearings – MPS Microsystems

 

MPS is specialised in miniature high precision linear bearings with tolerances of diameter under the balls < 8 µm.

 As a matter of fact MPS offers the smallest linear bearing available on the market.

  • Comprehensive range with bore diameters from Ø 2 mm to Ø 6 mm
  • Bore diameter tolerances +8/0 µm
  • Outer diameter tolerances 0/-8 µm

 

Customized Ball Screws

 

Most applications require specific mechanical interfaces, or special characteristics. Throughout a long-time experience with countless cases in various application fields MPS has acquired an exceptional level of expertise in the design and manufacture of customised ball screws, thus always gathering two essential features: precision and compactness.

 

Standard Ball Screws of MPS Microsystem

 

 

MPS offers a comprehensive range of miniature high precision ball screws with a positioning accuracy < 5 µm.

The ball screw technology that was developed by MPS leads to outstanding performances such as high efficiencies, smoothness and reliability.

 The MPS ball screws are entirely made out of stainless steel and all components are ground. They are fitted with a double nut to adjust the play.
