This heavy-duty mechanical end stop is designed specifically for profiled linear guide rails to establish a secure physical boundary along the axis of travel.
1
Overtravel & Derailment Protection
The stop block mounts rigidly to the rail, creating a robust physical barrier that halts the carriage in the event of motor runaway, software glitches, or control errors. By providing reliable overtravel protection, it prevents the bearing block from sliding off the rail end. This safeguard helps avoid the loss of internal recirculating steel balls and protects the carriage assembly from damage.

Compatibility
Engineered for seamless compatibility with industry-standard HG series and EG series profiles, including HG15, HG20, HG25 and EG15, EG20 rail systems."

Product Features & Engineering Advantages
Derailment Prevention
Engineered to prevent the linear carriage from sliding off the rail ends, minimizing the risk of internal ball bearing loss and protecting the carriage assembly from damage.
01
Physical Overtravel Limit
Functions as a robust mechanical limit stop, halting carriage travel during control anomalies, software faults, or motor malfunctions.
02
Profile-Matched Clamping
Precision-machined to match standard linear rail profiles. It clamps securely onto the non-bearing V-grooves without obstructing the travel path of the recirculating rolling elements.
03
Energy-Absorbing Bumper
Equipped with an integrated elastomer (rubber or polyurethane) buffer pad to absorb impact energy, reduce acoustic noise, and mitigate shock transmission to the machine frame.
04
Anodized Aluminum Housing
Fabricated from high-strength machined and anodized aluminum alloy to resist deformation under high-impact forces.
05
Key Functions of Guideway Stopper Blocks
Derailment Prevention
A primary function of a guideway stop block is to prevent carriage derailment.
The Hazard: Recirculating ball-type carriages (such as the HG or EG series) [1] rely on the rail profile to retain their internal rolling elements. If a carriage is driven past the end of the guide rail, the internal steel balls can easily escape and scatter, leading to immediate bearing failure.
The Solution: The stop block acts as a physical barrier at the rail’s limit. By preventing the carriage from sliding off the guide rail, it eliminates the risk of ball loss and protects the bearing block from becoming unusable.
Mechanical Limit (Fail-Safe Hard Stop)
While electronic limit switches detect positioning errors, they cannot physically stop a moving load during a hardware failure.
The Hazard: In the event of a motor malfunction, encoder glitch, or power surge, an axis may continue to drive, overriding software-defined limits.
The Solution: The stop block functions as a rugged mechanical hard stop. It mitigates damage during anomalous system operations by physically halting the carriage in the event of a motor failure or control overrun. This physical barrier absorbs impact forces, protecting surrounding tooling, sensors, and the machine frame from severe damage.
