SRW is an ultra-high rigidityRoller <strong>Guide</strong> that uses roller cages to allow low-friction, smooth motion and achieve long-termmaintenance-free operation.[Ultra-high Rigidity]Since it has a wide rail and can be secured on the table using two rows of mounting bolts, the mountingstrength is significantly increased. In addition, since the crosswise raceway distance (L) is large,model SRW is structurally strong against a moment load (Mc moment) in the rolling direction.Furthermore, model SRW uses rollers that show little elastic deformation as its rolling elements, andthe overall length of each roller is 1.5 times greater than the diameter, thus to increase the rigidity.Rolling direction moment(Mc moment)0.0015LSlant tanθ0.0010.000500 0.2 0.4 0.6 0.8 1Applied moment M (kN•m)Fig.1 Result of Comparison between Models SRW and SRG in Moment Rigidity in the Rolling Direction (Mc Moment)Width dimension: approx. 1.5 times greaterSRG45LRSRW70LR<strong>LM</strong> <strong>Guide</strong><strong>Industrial</strong> <strong>Technologies</strong>Fixed using two rows of mounting boltFig.2 Comparison between Models SRW and SRG in Cross SectionA1-295
