Steel Guide Rails
Robust steel guide rails for guiding slide cores smoothly.
Cross-Section & Material Variants
Steel guide rails dictate the trajectory precision of the slide core. Variations in geometry and material drastically affect lifespan and load capacity.
| Type | L-Shaped (Standard) | T-Shaped (Heavy Duty) | Square (Compact) |
|---|---|---|---|
| Load Capacity | Medium | High | Low |
| Machining Complexity | Low (simple pocket) | High (T-slot required) | Low |
| Retention Strength | Good | Excellent (captures slide) | Requires separate top plates |
| Typical Material | S45C / SKD11 | SKD11 / SCM440 | S45C |
| Hardness | HRC 45-50 | HRC 55-60 | HRC 45-50 |
Application Scenarios
Heavy Slide Core Actuation
For slide cores over 15kg where gravitational and actuation forces cause L-rails to deflect.
Recommended:T-Shaped SKD11 Guide Rails
Standard Cost-Effective Molds
Standard consumer goods molds requiring reliable but economical slide mechanisms.
Recommended:L-Shaped Induction Hardened Rails
Design Rule: Hardness of the guide rail should be 3-5 HRC points different from the slide core to prevent galling.
