MPS MICRO PRECISION SYSTEMS AG - Experts in custom-made microsystems

MPS Microsystems offers a complete range of high precision ball screws for positioning less than 5 µm. Mostly custom-made, these screws ensure smooth and uniform movement resulting from the high precision of their thread, achieved by grinding. Our ball screws are made exclusively of stainless steel and are fitted with double nuts to allow fine adjustment of the axial play. Moreover, an optional ogival thread can provide a higher static and dynamic load capacity. Thanks to a large number of options, we can ensure that the ball screw meets your technical and quality needs. The following parameters can be personalized: lubricant (grease, oil, dry lubrication, no lubrication), customized screw ends, shape and external dimensions of the nut and screw, multiple nuts on the same screw, left-hand thread, thread length, specific axial play, special surface treatment, and more.

MPS Microsystems is specialized in manufacturing high-precision, miniature linear bearings. We offer a comprehensive range of exceptionally smooth bearings with bore diameters from Ø 2 mm to Ø 6 mm. The balls of these precision bearings meet ‘Grade 3’, the highest quality defined by the ISO 3290/DIN 5401 standard. Combined with a cage and a high precision casing, they allow rapid positioning while reducing friction and eliminating the stick-slip effect. The standard version of MPS Microsystems linear bearings consists of a stainless steel bushing and balls, and a brass cage. An all-stainless steel version or one with ceramic balls can be made on request.

MPS Microsystems offers a wide range of linear bearings that provide smooth movement. Another advantage of these guidance systems: their attractive price. They are available in a range of diameters from Ø 3 mm to Ø 25 mm and are made of injected plastic segments (POM), as well as easy-to-clean stainless steel needles and balls. The needles have three roles: they hold the segments together, they serve as external tracks for the balls, and they define the diameter of the ball bushing. The plastic segments of MPS Microsystems DBL series linear bearings enable their use in environments with high temperature fluctuations.

Novostia, a Swiss startup founded in 2017, has entrusted MPS with the manufacture of its TRIFLO artificial valve, a revolutionary aortic prosthesis on several levels. Thanks to its aerodynamic design, the presence of three leaflets and the absence of physical pivot axes for the leaflets, the TRIFLO valve aims to satisfy the following three criteria: - A device lifespan at least equal to that of the patient, to avoid the need for a second surgical procedure. This means more than 30 million flap openings and closures per year, with no leaks, blockages, cracks, ruptures or flap escapes. - The artificial valve must not lead to thrombosis, so that patients do not need to take anticoagulants. - Operation (flap opening and closing, blood flow through the valve) must be as silent as possible, so as not to disturb the patient or those around him, day or night. The TRIFLO device is in clinical trial and is not approved for sale.
