Guide Rail Brake provides linear motion control.

Press Release Summary:

Spring-engaged, air-released, Guide Rail Brake provides maximum holding and/or dynamic braking, making it suited for power-off safety conditions. Unit is integrated into linear system and kept disengaged with air pressure. In disengaged mode, it allows nearly frictionless movement of carriage until air is exhausted and internal springs apply force on brake mechanism that clamps brake onto both sides of rail.

Original Press Release:

New Brake Provides Low Cost, High Efficiency Option for Linear Rails

(Vadnais Heights, Minn. - October 7, 2003) Nexen Group, Inc., today announced the Guide Rail Brake, their newest linear motion control device. The Nexen Guide Rail Brake is the most competitively priced and efficient brake on the market today. This spring-engaged, air-released unit is compact and easy to install in existing systems. It's designed for maximum holding and/or dynamic braking, which makes it ideal for power-off safety conditions.

The rail brake is easily integrated into a linear system and is kept disengaged with air pressure. In the disengaged mode, the brake allows nearly frictionless movement of the carriage until air is exhausted and the internal springs apply a force on the brake mechanism that clamps the brake onto both sides of the rail. A normally closed, directional control valve is open to the air supply when energized. In a power-off condition, the valve blocks the air supply allowing air to escape and the springs to apply the force to a clamping mechanism.

Nexen's Guide Rail Brake is able to hold large loads in all axes and performs dynamic stops within a short amount of time and distance. This product provides a high clamping force due to "Air Assist", which is the simultaneous movement of air and spring. The rail brake has a small air chamber, which means low air consumption, saving energy as well as operating time.

Nexen is a leading manufacturer of brakes, clutches, servo motor and linear motion brakes, torque limiters, overload protection devices, and web tension control systems for a variety of industrial applications ranging from motion control and robotics to packaging and material handling. With headquarters in Vadnais Heights, Minn., Nexen has more than 40 worldwide sales offices and more than 1,500 worldwide distributor sales outlets.
