结构 Structure 防尘盖型(ZZ型)Cage Type (ZZ)非接触橡胶密封圈式(RZ型)Non-contact Rubber Sealing Ring(RZ)接触橡胶密封(RS)Contact Rubber Sealing(RS)磨擦力矩Friction Torque 小Small小Small因是接触密封，所以RS1型、RS2型比ZZ型、RZ型大，但RS3型最大Because of contact sealing,Models RS1 and Models ZZ and RZ andModel RS3 is the biggest.高速性High Spesd Performance良好Good良好Good由于接触密封的极限(RS3型温升较高)Becausethelimit of contact sealing.(RS3 has a high temperature rise)脂密性Grease Sealing良好Good比ZZ型好Better than Mode RZ比RZ型略好，但RS1型胜于RS2型，RS3型胜于RS1型A little better than Model RZ but Model RSl is better than ModelRS2 and Model RS3 is better than Model RS1．防尘性Dust-proof良好Good比ZZ型好(多少有些粉尘的条件下也可以使用)Better than Model ZZ (could be usedin some dust environment)最好(粉尘多的环境条件下也可以使用)，但RS2型胜于RS1型，RS3型胜于RS2型The Best (could be used in most dust condition)but Model RS2is superior to Model RS1 and Model RS3 is superior to Model RS2.防水性Water Resistance不适Unsuitable不适Unsuitable良好(飞溅的条件下也可以使用)Good(could be used in splash condition)使用温度范围Range of Application Temperature-10～+110℃-10～+110℃-10～+110℃注:以上数值为标准品的范围，根据装入耐寒、耐热用油脂及密封用橡胶材质，则可以扩大温度范围，如有要求，请与CSR联系。Note:The descriprion is for srandard products only.However,the range of application temperature could be extended if you select cold resistant or hot resistant grease and rubber.Pelease contact CSR if you have any special requirement.
