Guiding unit RB50E+\L (left)

Application: Maintenance-free drive for roll screen systems in greenhouses and livestock buildings Material: Built into an aluminum tube with 50 mm diameter and 1.5 mm wall thickness Motor: Low-noise, single-phase, 2-pole asynchronous electric motor Limit switch: Precise electronic limit switch system with pulse counter (38 revolutions) Protection class: IP55 – high water resistance Torque: 50 Nm at 50 Hz Speed: 3.5 rpm at 50 Hz Ridder Article No.: 550032 The RB50E+ - 3.5-230/50/VK10/B50/L772 tubular motor is a powerful and maintenance-free drive unit for roll screen systems in greenhouses and livestock buildings. Thanks to its quiet operation and high water resistance, it is ideal for demanding environments. The integrated electronic limit switch system with pulse counter ensures precise control and protects the motor from overload. The IP55 protection rating allows reliable operation even in humid conditions. The motor is designed for intermittent operation and provides reliable braking performance, even under low voltage conditions.

Application: Roll screen systems in greenhouses Torque: 4.2 Nm Voltage: 115 V / 60 Hz Speed: 14 rpm Special feature: Maintenance-free tubular motor with integrated limit switch The RB50-4.2-14 tubular motor is a reliable and maintenance-free drive unit for roll screen systems in greenhouses. It is built into a standard aluminum tube with a diameter of 50 mm and can be fully wound up. The durable planetary gear ensures high efficiency and precise control. Thanks to the integrated brake, the motor stops smoothly and securely, enhancing the safety and stability of the system. The limit switch system is easy to adjust and allows for accurate positioning of the roll screen, ensuring optimal system performance.

Application: Drive unit for sidewall and twin-roll screen systems in greenhouses (not suitable for roof roll screens) Torque: 40 Nm Speed: 11 rpm Voltage: 230 V, single-phase, 50 Hz Power consumption: 1.1 A Tube diameter: 50 mm aluminum sleeve (standard) Limit switch: Mechanical, precisely adjustable over 38 revolutions Protection class: IP44 – sealed against water ingress from the roll tube Ridder Article No.: 550018 Special features: Maintenance-free tubular motor with integrated planetary gear and motor brake Thermal protection prevents overheating damage Virtually silent operation Suitable for intermittent operation (S3-6%, 4 min duty cycle) The RB40-11 tubular motor is a compact and powerful drive unit for roll screen systems in glass and film greenhouses. Thanks to its precise limit switch, robust construction, and quiet performance, it is ideal for medium-duty applications. The integrated 50 mm aluminum sleeve allows for space-saving installation, while the IP44 protection rating prevents moisture ingress—ensuring long-lasting and reliable operation.
