Users can choose according to the pulley series table according to the steel wire diameter d, the ratio of pulley nominal diameter DO and steel wire diameter d D0/d. bearing model. usage environment (requires general sealing or tight sealing (type A)) (Table 14 It is a general sealing type, Table 5-8 is a tight sealing type). Consumers may choose pulleys from pulley secries foms according to 10 stcel rope diancterld,ratio of pulley nominal diamcter DO with stcel rope diameter d,bearing type,condition for use (ordinarily sealed or tightly scaled(A-ypc)) (Form 14 is ordinarly scalod type.Form5-8is tight scaled lypec)   The annotation method is as follows: Note as fllowing If you choose a No. 1 rim, a general sealed pulley with a Do/d value of 20 and a bearing model of 211, mark WJ1201 For example,choose No. pulley ,Do/d ratio 20,bcaring type 211 of ordinarily scaled pulley,notc WJ1201
