Frequently Asked Questions

Q: What materials are these linear rail limiters made from?

A: The main body is crafted from high-grade aluminum alloy for a strong yet lightweight build, while the rolling housing uses bearing steel for smooth, durable contact with the rail surface.

Q: What rail sizes or systems are these slide block stoppers compatible with?

A: These fixing blocks are designed as standard parts suitable for common linear rail systems including those used in CNC routers, 3D printers, and automation equipment. Please check your rail width and block dimensions against the listed 5mm thickness and variant specifications before ordering to confirm fitment.

Q: Can these be used for both soft-stop and hard-stop applications?

A: Yes — the locking and fixing block design makes them suitable for both defining firm travel limits (hard stops) and securing block positions along a rail, giving you versatile control over your linear motion system.
