Product Description

The UMSB20-45A bearing integrates seamlessly with the 45mm UMSB coupling and UMSB45A motor unit, forming a compact industrial drive solution. Designed for automation and machinery systems, it operates within 12-24V DC, supports temperatures from -20°C to +85°C, and features RS-485/CAN communication interfaces. The system offers 2 digital inputs, 1 analog output, and direct connectivity to up to 4 peripheral modules. Its 45mm diameter shaft ensures compatibility with standard industrial components. Advantages include high torque transmission, low backlash, and IP65-rated durability, though installation requires precise alignment. Equipped with a 3.5-inch status display, a 2000mAh backup battery, and optional 5mm proximity detection, it suits robotics, CNC equipment, and conveyor systems. The modular design simplifies maintenance but increases initial configuration complexity.
