The standard equipped seal band covers the guide, ball screw and belt, preventing grease and external foreign matter from splashing and entering the LEF. There are 2 types of drivers

The 25A- series variations are compatible with secondary battery manufacturing for electronics, automotive, and other vehicle types.  Design goals include eliminating copper (Cu) and zinc (Zn) materials where possible, and employing a low dew point grease that retains lubricity even in low manufacturing temperatures.  Please note that copper and zinc materials are used for the motors
