NexSafe™ Functional Safety Certified Brakes for Pneumatic Cylinders or Round Shafts and Rails

Rod Locks Designed and Built Specifically for Almost All Pneumatic Cylinders or Round Shafts and Rails. Precision holding with guide rod systems and NFPA or ISO Pneumatic Cylinders.
A New Standard in Performance
Nexen’s Spring Engaged, Air Released Rod Locks are safety certified to comply with international safety standard ISO 13849-1. Category Level up to 4 and Performance Level up to e, able to be achieved using NexSafe™ products in recommended configuration.

Pneumatic Cylinder or Round Shaft and Rail Versions
With superior performance, these spring-engaged, air-released units supplement air cylinders and guide rods for holding in power-off/e-stop situations. High clamping forces ensure positive holding with minimal air required for release. Choose from our standard products, or we will work with you to meet your unique application specifications.
INDUSTRY 4.0 SOLUTION Nexen’s Rod Lock Operating Mode Sensors for either Engagement or Disengagement are Industry 4.0 compatible and can provide information to maximize machine efficiency. Having this information available aides with:
- Accurate Linear Positioning
- Predictive Maintenance
- Operational Feedback
