introducing the hepcomotion® lbg linear ball guides hepco s lbg linear ball guides offer a comprehensive range of sizes precisions and pre-load options designed to meet a broad range of applications where quality accuracy capacity high reliability and interchangeability across international standard are considered prime requirements the lbg range has been designed and constructed around the four row angular contact ball track concept thereby offering distinct user benefits such as low friction and reduced differential slip higher loads installation compliance and the ability to absorb minor errors on the mounting surfaces without compromising smooth movement and system performance figure 1 in keeping with hepco tradition the lbg range offers several unique design features setting it apart from other ball based linear guideways the newly developed ball recirculating system has excellent performance characteristics resulting in reduced friction low noise and smooth movement as with all bearing based recirculating systems it is important to ensure that the blocks are kept well lubricated during operation and regular lubrication intervals are observed the built-in felt wiper within the lbg block aids lubrication helping to maintain a positive oil film at the bearing contact surfaces figure 2 the hepco lbg range rails blocks can be specified with a corrosion resistant treatment for added surface protection please contact hepco s technical department for details hepco lbg four row angular contact configuration bearing block configuration top retainer lubrication felt steel balls lbg block 45° 90° 45° retaining screw grease nipple bottom retainer figure 1 scraper/seal end plate recirculation unit figure 2 hepco lbg features and benefits · built-in felt wiper aids lubrication · new recirculation system smooth running/improved performance · range of precisions satisfies a broad range of applications · integral all round sealing added protection · corrosion resistant option surface protection · high accuracy high levels of repeatability · competitive prices low installation costs · ex-stock delivery order with confidence · angular contact configuration equal load carrying in four directions · interchangeable with international standard 1[close]

technical data load/life basic static/dynamic load rating co c when a linear guide system is subjected to extreme load or impact permanent deformation can occur between the raceway and rolling elements should deformation become excessive the running quality smoothness and efficiency of the guideway will be impaired the definition of basic load rating co is stated as a static load of constant magnitude acting in one direction under which the sum of the deformation of the elements and race way equals 0.0001 times the diameter of the rolling elements basic dynamic load rating c is the load of constant magnitude acting in one direction that results in nominal life of 50km for a guideway using balls basic static moment rating ms m mv the basic moment ratings in the ms m and mv direction are stated as static moment capacities in the load rating charts see pages 5-7 m l1 ms l2 l max lbg mv safety factor static fa the static safety factor fa should be considered related to the basic load rating co the acting load and the operating condition reference value of the static safety factor fa in given operating conditions is stated as follows factor fa operating condition static applied load condition small impact high impact load dynamic small impact high impact load minimum fa 1.0 1.4 2.0 3.0 1.0 2.0 2.5 6.0 fa fb x co p or fa fb x mo m fa co p m fb mo static safety factor basic load rating static applied load applied moment mounting factor permissible static moment 12[close]
