Nexen offers RB and RBE Series rail brakes

Nexen rail brakes are available in spring-engaged and electric models, delivering a secure hold in the broadest range of linear motion-control applications.

RB Series spring-engaged rail brakes use spring forces to secure the load in holding applications, providing superior response time and high stopping and holding force for e-stop and power-off situations.

RBE Series electric rail brakes provide fast response times, low backlash and on-board controller logic for electric holding on profile rails.

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.

The RB Series spring-engaged rail brakes deliver high air-released holding forces, providing an ideal solution for stopping and holding in e-stop and power-off applications.

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; by accurately holding this position, the rail brakes eliminate drive train backlash and elasticity.

The RB Series spring-engaged rail brakes also offer: brake geometry similar to system bearing cassettes, allowing simple installation; adjustable facing gap for optimum brake performance; field serviceable friction-facing replacement; large friction-facing contact area; and no lubrication or periodic maintenance requirements.

The RBE Series electric rail brakes provide a response time 54 per cent faster than that of competing models.

They 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 and substantial opening of the shoes, eliminating system friction and allowing for minor variations in rail alignment, while still providing optimal performance.

Since the brakes lock in place and maintain a precise hold, they are not recommended for e-stop or dynamic braking applications.

Additional features of the RBE Series electric rail brakes include: clamping feedback, via cable and on-board LED; high holding force, used when the drive cannot perform the brake function on its own; and stiffness to eliminate vibration in linear-drive systems.
