Rail brakes

Nexen RB and RBE series rail brakes are available in spring-engaged and electric models, delivering a secure hold in the broadest range of linear motion control applications. Both RB series spring-engaged and RBE series electric rail brakes configure to fit most profile guide rails including: NSK, SKF, INA, THK, IKO, HIWIN and Star.

Engineered for dependant redundant braking applications, the RB series spring-engaged rail brakes help ensure operator safety. The brakes maintain an accurate position on the centre of the guide rail, ensuring positive braking and holding in all axes, and by accurately holding this position, the rail brakes eliminate drive train backlash and elasticity.

The RBE series electric rail brakes use mechatronic technology to combine the latest electronic and mechanical components and ensure maximum power, density, efficiency and robustness. An onboard microcontroller receives and sends the engage/disengage signals to the drive components, eliminating the need for a space-consuming, externally mounted controller. Upon engagement, the microcontroller provides digital feedback, and power can be removed with the full holding force still remaining. When disengaging, the brake makes no rail contact with a substantial opening of the shoes, eliminating system friction and allowing for minor variations in rail alignment, while still providing optimal performance. As the brakes lock in place and maintain a precise hold, they are not recommended for e-stop or dynamic braking applications.
