How to find the right Industrial Linear Brakes AI guide
Written by an AI model from its trained knowledge.
What the AI looks for in Industrial Linear Brakes
- Holding vs dynamic braking
- Confirm whether the unit is rated only for static holding or also for emergency dynamic stops. A holding-only clamp used to stop a moving load wears fast and may not stop it.
- Fail-safe engagement
- Use spring-engaged units that release with air or power for vertical axes and safety holding. Power-engaged units are for positioning only. Only a spring-engaged unit holds the load when air or power is lost.
- Holding force margin
- Size holding force above the worst-case load, including gravity on vertical axes and acceleration forces, with the safety factor your machine standard requires. Rated force is a nominal value and drops with oil, wear or low supply pressure.
- Rod or rail fit
- Rod locks must match the rod diameter and surface finish. Rail clamps must match both the rail size and the rail manufacturer's profile. Profiled rails of the same nominal size differ between makers, and a poor fit cuts holding force sharply.
- Actuation supply and response
- Check the release pressure or voltage against what the machine provides, and check that engagement time suits the stopping distance. Low release pressure leaves the brake dragging, and slow engagement lengthens drop distance.
Brands that matter
- Nexen: Pneumatic rod locks and linear rail brakes, including spring-engaged versions.
- Zimmer Group: Clamping and braking elements for profiled linear guides and rods.
- Mayr: ROBA linear brake and rail-guide brake families for safety applications.
- SMC: Pneumatic cylinders with integrated end or rod locks.
- Festo: Clamping units and cylinders with locking for its own actuator ranges.
What to avoid
- Using a cylinder's integrated end lock as a mid-stroke safety brake.
- Rail clamps chosen by nominal size without checking the rail maker's profile.
- Running clamps on oily or chrome-damaged rods when the rating assumes a clean, specified finish.
Questions
Is a rod lock the same as a safety brake for a vertical axis?
Only if it is spring-engaged and rated for that use, and many are holding-only. Check the safety rating and dynamic stop rating before relying on it to protect people.
