The SE series is a classic and widely used type of slewing drive. Its core design typically integrates a "single-row ball slewing bearing with a worm gear drive". It is essentially a complete electromechanical "slewing assembly" that highly integrates the slewing bearing, gear reducer, drive motor, and brake. It provides customers with a "ready-to-install" solution.
Compact structure, space-saving
High reduction ratio, large output torque
Self-locking function, high safety
Smooth operation, high precision:Multi-tooth engagement ensures stable transmission and low noise
Easy installation and maintenance:Simply bolt the fixed ring to the base, connect the rotating ring to the load, and connect the motor power supply
High rigidity, anti-overturning:The single-row ball slewing bearing can withstand axial force, radial force, and overturning moment simultaneously, making it suitable for complex loading conditions
Core applications revolve around needs for "low speed, heavy load, and precise positioning or self-locking."
