Introduction to Elevator Three-In-One Guide Shoe Lining 230 × 10 mm
Produced and distributed worldwide by NANJING ZHUYE ELEVATOR PARTS

Overview
The Three-In-One Guide Shoe Lining 230 × 10 mm is an advanced, multi-purpose insert that combines car-side, counter-weight-side and emergency-landing guide functions into a single, ultra-durable strip. Manufactured by NANJING ZHUYE ELEVATOR PARTS, it is engineered for traction and hydraulic elevators up to 4 m/s and 2 500 kg rated load, and complies with EN 81-20/50, ASME A17.1 and GB/T 24478.

1. Dimensional & Tolerance Data
• Nominal size: 230 mm (L) × 10 mm (W) × 4 mm (T)
• Length tolerance: ±0.2 mm; width & thickness: ±0.05 mm
• Radius options: 350 mm, 450 mm, 600 mm to match rail profiles
• Weight: 38 g per strip; supplied in 50-piece anti-static bags

2. Material Composition & Properties
• Substrate: oil-impregnated aramid-fiber composite for high strength and vibration damping
• Friction layer: PTFE/graphite blend, reducing coefficient of friction to ≤ 0.15 (dry) and ≤ 0.08 (lubricated)
• Backing: stainless-steel mesh vulcanised into the composite for tear resistance up to 180 N/mm²
• Operating temperature: –40 °C to +120 °C, suitable for extreme climates
• Fire rating: UL94 V-0 self-extinguishing, non-toxic smoke emission

3. Key Performance Features
• Noise Reduction
– Micro-cellular surface absorbs vibration, lowering sound levels by 8–10 dB(A) versus traditional nylon linings.
• Wear Resistance
– Laboratory accelerated tests show < 0.02 mm wear after 2 million cycles under 2 500 N side load.
• Lubrication-Free Option
– Graphite-PTFE matrix eliminates need for oil grooves, saving maintenance hours and environmental contamination.
• Universal Compatibility
– Fits T45/A, T50/A and T70/A guide rails; 3-point dovetail slot allows easy retrofit without rail modification.
• Emergency Landing Function
– Integrated sacrificial layer engages during unintended overspeed or buffer impact, preventing rail damage.

4. Installation Advantages
• Pre-scored break lines at 5 mm intervals enable on-site length adjustment with ordinary scissors.
• Self-adhesive peel-off backing guarantees bubble-free placement in under 30 seconds.
• Colour-coded edges (blue = car side, red = counter-weight side, yellow = emergency) reduce installation errors.

5. Sustainability Credentials
NANJING ZHUYE ELEVATOR PARTS operates ISO 14001-certified plants; the lining is RoHS 2.0 and REACH compliant. Scrap generated during CNC cutting is recycled into secondary composite products.

6. Typical Applications
• High-speed passenger elevators (2.5–4 m/s) in commercial towers
• Freight elevators exposed to heavy side loads
• Machine-room-less (MRL) systems with restricted lubrication access
• Modernisation projects where rail replacement is cost-prohibitive

7. After-Sales Support
Every batch is laser-marked with a unique QR code linking to digital certificates (material traceability, test reports). NANJING ZHUYE ELEVATOR PARTS provides 24-hour technical hotline, on-site training, and global next-day spare-part logistics. Custom colours, logos, or special dimensions (e.g., 250 × 12 mm) are available with a 7-day lead time.

Conclusion
By integrating the Three-In-One Guide Shoe Lining 230 × 10 mm from NANJING ZHUYE ELEVATOR PARTS, specifiers achieve quieter rides, longer service intervals, and reduced life-cycle costs—while meeting the strictest international safety and environmental standards.
