FAQs
What is the main function of the RSB Series safety brakes?
The RSB Series safety brakes are mechanical safety devices designed for roller shutter door and window systems. They are used to prevent accidental door falls caused by lifting system failure by instantly locking the shaft in emergency situations.
What door weight range does the RSB Series cover?
The RSB Series covers a wide load range from 500KG to 1500KG, with three models available:
RSB-1-30: up to 500KG
RSB-1-40: up to 1200KG
RSB-1-50: up to 1500KG
This allows precise matching for different industrial and commercial door systems.
What are the torque capabilities of each RSB model?
Each model is designed for different load requirements:
RSB-1-30: static run torque 368 N·m, instant max torque 1444 N·m
RSB-1-40: static run torque 650 N·m, instant max torque 2058 N·m
RSB-1-50: static run torque 1031 N·m, instant max torque 3509 N·m
These torque levels ensure rapid and reliable braking under emergency conditions.
What operating speed and winding radius are supported?
The RSB-1-30 and RSB-1-40 operate at a maximum speed of 22 r/min, while the RSB-1-50 operates at 20 r/min. Maximum winding radius varies by model, ranging from 145 mm to 189 mm, supporting different roller shutter shaft sizes.
What installation and fastening requirements should be considered?
Bolt tightening torque differs by model to ensure secure mounting:
RSB-1-30: 15 N·m
RSB-1-40: 28 N·m
RSB-1-50: 35 N·m
Proper installation torque is critical to guarantee braking performance and long-term reliability.
Where are RSB Series safety brakes typically used?
The RSB Series is widely used in industrial roller shutter doors, commercial warehouses, logistics centers, factories, and large door systems where high load capacity and reliable fall protection are required.
