Profile Guide Rail Brakes from Nexen Group, Inc. are now available in a wider range of sizes, from 15 to 65 mm, and are fully compatible with an even wider range of guide rail manufacturers, including THK, NSK, IKO, HIWIN, INA, SKF, Star, Bosch, Accu Tech and Schneeberger. As a result, they provide great first fit and ideal redundancy in a wide range of OEM and aftermarket applications. Profile guide rail brakes provide fast engagement at 0.049 to 0.080 seconds, high static holding force to 2,600 N (585 lb), and can be combined to provide higher holding forces as needed. They also offer maintenance-free operation.
“Nexen rail brakes are a versatile solution that can be easily retro-fitted in the field, as well as designed into original equipment,” says Hank Schilling, Motion Control Product Manager, “and with brake body geometry that perfectly matches the guide rail bearings, coupled with an adjustable shoe gap, profile guide rail brakes are quick and easy to install.”
The Nexen rail brake design offers low backlash, accurate positioning, and excellent reliability. Rail brakes are ideal for holding a load in position while failed reducers or motors are replaced. They also allow for the use of smaller drive systems because the brakes position and hold a load that might otherwise overpower the drive system. The rail brakes clamp onto the center of profile guide rails to provide positive braking and holding in all axes without touching the bearing surface of the rail.
