Linear Guideway Stopper Block

Product Profile: Linear Guide Stopper Block for HG and EG Series Rails

A linear guide stopper block is an essential mechanical end-stop accessory engineered for profiled linear guideway systems. Installed securely at the travel limits of a linear guide rail, it establishes a positive physical stop to prevent the bearing carriage from overtraveling beyond the supported rail section.

YONGRUN linear guide stopper blocks are precision-manufactured for industrial linear motion assemblies, including CNC machine tools, automation equipment, and multi-axis positioning systems. Sized to match standard rail profiles and mounting dimensions, these blocks provide dependable mechanical protection to enhance overall system reliability.

Contact our technical team with your rail series, size, and application requirements to confirm dimensional compatibility and request a quotation.

Key Features & Engineering Advantages
Mechanical Overtravel Protection: Serves as a rigid physical barrier at the rail ends to prevent carriage runoff during unexpected overtravel events, mitigating the risk of bearing block detachment and internal ball loss.

Profile-Matched Compatibility: Engineered specifically for standard HG and EG series profile guide rails (e.g., sizes 15 through 30). Verify rail profile and mounting hole pitch prior to ordering.

Integrated Impact Damping: Available with an elastomeric (rubber or polyurethane) buffer pad to absorb kinetic shock and dampen contact noise when the carriage reaches the physical travel limit.

Hardware-Level Fail-Safe: Provides a dependable physical boundary that does not rely on electrical sensors or software limits, serving as a mechanical backup alongside electronic limit switches.

Broad Industrial Suitability: Suitable for CNC milling routers, pick-and-place automation, inspection stages, and general linear actuators requiring positive travel limits.

Product Selection & Engineering Compatibility

Choosing the right linear guide stopper block helps limit carriage travel and protect mechanical assemblies from unintended overtravel. To verify compatibility, please provide the following details:

Guide Rail Series: HG, EG, or other linear guide series.

Rail Size: Model number or nominal rail width, such as 15, 20, 25, or 30 mm.

Mounting Dimensions: Hole spacing, thread size, mounting position, and available installation space.

Operating Conditions: Moving mass, travel speed, and expected stopping or impact conditions.
