1 U.S. PATNTD Low Decibel Linear Way LWQLWTQLWSQ Low Decibel Linear Way series Sape lange type mounted from bottom Low Decibel Linear Way is a linear motion rolling guide for smoot and quiet motion. Its low noise caracteristic as been acieved by adopting optimum design based on a toroug analysis of ball recirculation beavior and sound quality. Plastic separators are incorporated to eliminate direct contact between balls and tus acieve smoot and quiet motion. Low Decibel Linear Way is suitable for production equipment or macinery, in wic a large number of linear motion rolling guides are incorporated, and can be used to elp reduce te noise level in factory and create a uman-friendly environment. lange type mounted from top LWQ Low decibel Plastic separators are incorporated to eliminate direct contact between balls and tus acieve smoot and quiet motion. lange type and block type Slide units are available in tree different sectional sapes; two flange types for different mounting directions and one block type wit a narrow widt. Low Decibel Linear Way LWTQ Compact design Lower, narrower, and sorter. Compactness as been pursued in every dimension. Dimensional intercangeability wit Linear Way Te mounting dimensions are te same as tose of Linear Way. So tis guide can replace Linear Way (LW) wit little modifications of macines or equipment. lock type mounted from top LWSQ Track rail U.S. PATNT No.,17,17 No.,97,7 No.,,188 No.,7,12 No.,,22 No.,2,11 No.,2,17 LWQ, LWTQ, LWSQ Casing Steel ball Under seal Separator all retaining band nd plate nd seal Grease nipple Slide unit Structure of Low Decibel Linear Way - 1=0.097inc -7
