Product Description

VRB series precision planetary gear reducer provides high cost performance, wide application, economical and practical, long life and other advantages. In the application of servo control, it exerts a good servo rigidity effect, accurate positioning control, and has medium-term stability on the operation platform. Low backlash, high efficiency, high input speed, high input torque, smooth operation, low noise and other characteristics, the appearance and structure design are light and small. It uses lubricating oil that does not need to be replaced for life, and can be operated without maintenance no matter where it is installed.

The fully enclosed design has an IP65 degree of protection, so it can be used even in poor working environments. VRB can provide 9 frame specifications; the backlash is 3 arc minutes; the maximum torque can reach 1200NM; the maximum radial load capacity is 12400N; the ratio of 4:1 to 1000:1 can be provided; any kind of motor can be connected; work The lifespan is about 20,000 hours.

VRB series precision planetary gear reducers are suitable for a variety of industries and applications, including: printing and paper processing; CNC machine tool processing equipment; military and aerospace equipment; semiconductor wafer manufacturing; coating and film processing; high-speed electronic assembly; injection casting, Packaging; CNC plasma flame cutting equipment; automated packaging equipment, printing machinery.
