Nexen Group, Inc.

Linear motion accessories include ISO adapters, ISO preloaders, rack segment alignment tools, and gear tooth lubrication for the Roller Pinion System. Accessories for pneumatic linear brakes include proximity sensors for rod locks, ball screw brake couplings, 3 way valves, filters, lubricators, and regulators.

Spring engaged, air released servo motor brakes mount to the shaft end of servo motors up to 20 horsepower. The brake acts as an adapter between dissimilar mounting features. The brake bore accepts the motor shaft that is fixed inside the brake with a split hubshaft collar. This brake is a high-torque, zero backlash device.

Linear Couplings Provide Zero Backlash Misalignment Control Between Linear Actuators Like Linear Motors, Ballscrew Actuators, Pneumatic Cylinders, And Rods Or Sensors They Drive To Prevent Binding Or Premature Wear.

Nexen’s I-300 brake is designed for zero backlash holding and emergency stopping making it ideal for indexers and positioning systems. The spring engaged, air released, patented braking element locks and holds the shaft in position without any displacement or reversing of the load. It is flange or shaft mounted and has a keyless compression bushing shaft connection for easy installation and IP67 rated when flange mounted.

Ball Screw brakes provide reliable holding in a compact package. During a power loss the motor has no holding torque allowing the ball screw to back drive and the load to drop. Ball screw brakes connect to the machined end of the ball screw to prevent back driving, load drops and equipment damage during a power loss. Holding force up to 125 Nm (1100 in-lbs.)

PROFILE RAIL BRAKE FEATURESBENEFITS: • Large friction facing contact area for consistent performance and low rail wear • Field serviceable friction facing replacement • Ideal for power-off, e-stop and holding applications • Low backlash for accurate position holding • Brake geometry is similar to linear bearing cassettes for easy installation • Provides stiffness and eliminates vibration in linear drives • Large clearance between brake and rail compensates for installation misalignment • No lubrication or periodic maintenance required • Models available to fit most common profile guide rails • Highest spring engaged air released holding force on the
