Индастриал Технолоджис www.industrial‐technologies.com.ua +38 044 498 21 94Features of Each ModelCross LM Guide Model CSRStructure and FeaturesBalls roll in four rows of raceways precision-ground on a LM rail and a LM block, and endplates incorporatedin the LM block allow the balls to circulate. Since retainer plates hold the balls, they do notfall off even if the LM rail is pulled out.This model is an integral type of LM Guide that squares an internal structure similar to model HSR,which has a proven track record and is highly reliable, with another and uses two LM rails in combination.It is machined with high precision so that the perpendicularity of the hexahedron of the LMblock is within 2 μm per 100 mm in error. The two rails are also machined with high precision in relativestraightness. As a result, extremely high accuracy in orthogonality is achieved. Since an orthogonalLM system can be achieved with model CSR alone, a conventionally required saddle is nolonger necessary, the structure for X-Y motion can be simplified and the whole system can be downsized.[4-way Equal Load]Each row of balls is placed at a contact angle of 45° so that the rated loads applied to the LM blockare uniform in the four directions (radial, reverse radial and lateral directions), enabling the LM Guideto be used in all orientations.[High Rigidity]Since balls are arranged in four rows in a well-balanced manner, this model is stiff against a moment,and smooth straight motion is ensured even a preload is applied to increase the rigidity.The rigidity of the LM blocks is 50% higher than that of a combination of two HSR LM blocks securedtogether back-to-back with bolts. Thus, CSR is an optimal LM Guide for building an X-Y table thatrequires high rigidity.LM GuideIndustrial TechnologiesA1-227
