Product Description

Gearbox output shaft supported by two coupled and sealed ball bearings. The gearbox and motor have a surface treatment to resist corrosion. The BLDC motor is equipped with anti-interference filters in compliance with CE regulations. Low voltage power supply 24 Vdc S1 operation is continuous operation with an overtemperature of 70° C in free air. The inrush current must not be maintained for more than max 2''. Motors with encoders of 1000, 1024, 2500 pulses per revolution are available. Maximum forces that can act on the output shaft: Axial 100 N, Radial 150 N at the extreme point of the output shaft.

Every Bernio gearmotor is designed to operate for long periods under load with stable performance over time. High-precision mechanics, combined with optimized lubrication, minimizes backlash and vibrations even in harsh duty cycles. As a result, the drive system maintains efficiency and stability, reducing the risk of unplanned downtime.

Main features

Compact solutions engineered for easy integration into existing machines.
Stable performance even with frequent starts and stops.
Torque available already at low speed ranges.
Gear units conceived to minimize unplanned downtime.
Configurations customizable according to the application.
