Component Specifications

Definition
Guide rails and bearings are critical linear motion components that provide smooth, accurate, and low-friction guidance for moving parts in coil ejection systems. They ensure precise positioning and controlled movement of ejection mechanisms during material handling operations.
Working Principle
Guide rails provide a hardened, precision-ground track for linear movement, while bearings (typically linear ball bearings or roller bearings) reduce friction by rolling along the rail surface. This combination converts rotational motion from drive systems into precise linear motion with minimal energy loss.
Materials
Guide rails: Hardened steel (AISI 52100, 440C), stainless steel (AISI 304, 316). Bearings: Chrome steel balls/rollers, stainless steel cages, polymer seals. Coatings: Black oxide, zinc plating, or specialized coatings for corrosion resistance.
Technical Parameters
  • Rail Length Standard: 500-4000 mm, Custom: up to 6000 mm
  • Load Capacity Dynamic: 500-5000 N, Static: 800-8000 N
  • Accuracy Grade Normal (N), Precision (P), Super Precision (SP)
  • Precision Tolerance ±0.01 mm/m
  • Lubrication Interval 1000-5000 operating hours
  • Operating Temperature -20°C to +80°C
Standards
ISO 10285, ISO 3408, DIN 645, DIN 636
