Lubricating greases - Import export

The resistance generated by the seal (if present), depending on the surface finish of the outside diameter of the inner ring, as well as of the rotational speed. The resistance generated by the cage, depending on the geometrical form and the machining quality of the cages. The resistance generated by the lubricant, depending on the lubricant viscosity and filling quantity as well as the rotational speed. At low speed and with fine instrument oil this resistance is insignificant. It will be higher at low temperatures and at high viscosity of the lubricant. Grease lubricated bearings will show, according to the grease type and filling, a much higher friction torque than oil lubricated bearings.

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.
