托輥是帶式輸送機的重要部件，種類多，數量大。它占了一臺帶式輸送機總成本的35％，承受了70％以上的阻力，因此托輥的質量尤為重要。 　　托輥的作用是支撐輸送帶和物料重量。托輥運轉必須靈活可靠。減少輸送帶同托輥的摩擦力，對占輸送機總成本25％以上的輸送帶的壽命起著關鍵作用。雖然托輥在帶式輸送機中是一個較小部件，結構并不復雜，但制造出高質量的托輥并非易事。 DTIIA上托輥組 30 35 45帶寬輥子AEH1H2PQd質量kg圖號DLRKM-RS/LS/NS軸承C335。45。35。45。35。45。50089200RS89-204-2006204740800135.5298328170130M14161750C31450C31565089250RS89-204-2506204890950135.5327364170130M12181965C31465C315108RS108-205-2506205146346381222265C41465C41580089315RS89-204-315620410901150135.5364410170130M12222380C31480C315108RS108-205-3156205146383427272880C41480C415133RS133-305-3156305159.5407455333580C51480C5151000108380RS108-205-380620512901350159437487220170M163841100C414100C415133RS133-305-3806305173.54615154649100C514100C5151200108465RS108-205-465620515401600176502564260200M165154120C414120C415133RS133-305-4656305190.55275926063120C514120C515159RS159-306-4656306207.55566187376120C614120C6151400108530RS108-205-530620517401800184548618280220M165668140C414140C415133RS133-305-5306305198.55736466677140C514140C515159RS159-306-5306306215.56026728893140C614140C6151600133600RS133-306-600630619802050212.5629721300240M16105107160C614160C615159RS159-306-6006306225.5653734114117160C714160C715RS159-307-6006307121123160C814160C8151800133670RS133-306-670630621802250212.5670770340270M16115120180C614180C615159RS159-308-6706308225.5693783139141180C714180C715194RS194-307-6706307247714805161164180C814180C8152000159750RS159-308-750630824202500235.5749850
