Motorized Pulley 320L, 320M & 320H, Ø in. (321 mm)

Transcription

1 Mtrized Pulley 320L, 320M & 320H, Ø (321 mm) Our diameter Mtrized Pulley range fers three different perfrmance levels fr BULK applicatins: - L fr Light duty - M fr Medium duty - H fr Heavy duty It is imprtant t nte the prduct differences and chse the apprpriate pulley based n estimated belt tensin (radial lad.) See page 78. The actual radial lad must be less than the maimum allwable radial lad shwn this catalg. Be aware creased belt tensins required t drive multi-ply thick heavy belts and/r larger belt widths. If the diameter mdel is nt strng enugh t resist estimated belt tensin, then select diameter mdel. L fr Light duty 320L is designed fr regular and cntuus peratg cnditins. It is advisable t rubber lag these pulleys t grip the belt and limit belt tensin. Typical applicatins are prtable cnveyrs and crss belts mbile crushg and screeng equipment. 320L shuld nt be used fr lw speed high trque feeder cnveyrs. 320L uses mtr and gearb frm 220M. M fr Medium duty The ternal parts 320M are designed fr tugh and irregular peratg cnditins (e.g. crushg & screeng applicatins, asphalt, cement, and cncrete plants.) H fr Heavy duty A slid 3-stage gearb, larger shafts, and strnger beargs enable the 320H t prvide lw speed at high trque and handle irregular ladgs harsh peratg cnditins.
