Introduction to Elevator Guide Shoe Lining
Manufactured by NANJING ZHUYE ELEVATOR PARTS

The guide shoe lining is the thin but critical interface between elevator car or counterweight frames and the guide rails. NANJING ZHUYE ELEVATOR PARTS has developed a complete range of linings that combine friction control, noise suppression, vibration damping and long wear life into one compact strip. Every batch is produced in our ISO 9001 & ISO 14001 certified plant and is CE, UL and RoHS compliant.

1. Product Family & Dimensions
• Standard thicknesses: 3 mm, 4 mm, 5 mm
• Widths: 8 mm, 10 mm, 12 mm, 15 mm (custom up to 25 mm)
• Lengths: 200 mm – 400 mm in 10 mm increments; pre-scored for on-site cutting
• Radii: 350 mm, 450 mm, 600 mm to match T45/T50/T70 rails
• Weight: 28–45 g per strip depending on size

2. Three-Layer Composite Construction
a. Friction Layer
– PTFE / graphite blend, coefficient of friction ≤ 0.12 (dry) and ≤ 0.06 (lubricated)
– Reduces stick-slip noise by 6–8 dB(A) versus nylon linings
b. Reinforcement Layer
– Aramid-fiber mesh encapsulated in oil-impregnated phenolic resin
– Tensile strength ≥ 180 MPa, elongation at break ≥ 3 %
c. Backing Layer
– Stainless-steel micro-mesh vulcanised into the composite
– Prevents tear propagation and ensures firm seating in dovetail slots

3. Key Performance Features
• Wear Life: < 0.02 mm loss after 2 million cycles at 2 500 N side load (TÜV test)
• Temperature Range: –40 °C to +120 °C without embrittlement or softening
• Fire Rating: UL94 V-0, smoke density < 200 Dm (ASTM E662)
• Chemical Resistance: Resists hydraulic fluid, cleaning solvents and salt spray (1 000 h ASTM B117)
• Lubrication Options: Dry-running, light-oil, or graphite-impregnated versions

4. Installation Advantages
• Pre-applied 3 M VHB adhesive strip for one-hand positioning
• Colour-coded edges (blue = car, red = counterweight, yellow = emergency) eliminate mix-ups
• Snap-fit dovetail profile allows replacement in < 60 seconds without removing shoes

5. Sustainability & Compliance
NANJING ZHUYE ELEVATOR PARTS uses solvent-free lamination and recycles 92 % of production scrap. All materials are REACH & RoHS 2.0 compliant, and halogen-free on request.

6. Applications
• Passenger elevators up to 4 m/s and 2 500 kg load
• Freight elevators with high side forces
• Machine-room-less (MRL) units where space is restricted
• Modernisation projects where rail replacement is cost-prohibitive

7. After-Sales Support
Each liner carries a laser-etched QR code linking to digital certificates (material traceability, test reports). NANJING ZHUYE ELEVATOR PARTS provides 24-hour technical support, on-site training, and global next-day spare-part delivery. Custom colours, company logos, or special dimensions can be supplied within seven working days.

Conclusion
Specifying the guide shoe lining from NANJING ZHUYE ELEVATOR PARTS delivers quieter rides, extended maintenance intervals, and lower total cost of ownership while meeting the strictest international safety standards.
