News ReleaseNEW QUALITY GRADE SF-CLASS FOR Linear bearings OFFERS MAXIMUM PERFORMANCE
Dedemsvaart – The Netherlands, September 6, 1999 PM – BEARINGS BV (PM) announces a new innovative quality grade for their crossed Roller bearings – Option SF-class. SF-Class (Super Finish) is used in certain optical and electronic scanning applications where vibrations can affect the reading of accuracy of the system. Other applications are fiber optic splicing equipments and wire bonding stages which require the highest class in accuracy and reliability. SF class offers a runout of no more than 2 micron over a travel distance of 1200mm. The highly polished V-grooves provide the smoothest motion of any mechanical bearing system together with an extremely consistent virtually zero frictional force, which make this bearing well suited for applications where a precise reading of axial force must be obtained. The surface roughness of the V-grooves is less than 0.05 Ra instead of conventional guides with 0.1Ra. PM ’s SF-class can provide linear travel in sub-micron range and is now available in all precision crossed roller slides and positioning Tables. PM is a leading manufacturer of high precision linear bearings, slides and stages. Their products are meeting the highest accuracy and quality demands of today’s industry and are successful in use worldwide. The wide range of products offers designers maximum flexibility to match every requirement in linear and rotary motion applications.
