Elevator Guide Shoe Lining 130 mm × 10 mm
Usage, Replacement Cycle & Maintenance Guide
By Nanjing Zhuye Elevatorparts

Introduction
The 130 mm × 10 mm elevator guide-shoe lining is a precision-engineered insert that keeps elevator cars gliding smoothly along the rails while protecting both the shoe and the rail itself. Manufactured by Nanjing Zhuye Elevatorparts, this composite lining meets EN 81-20/50 and ASME A17.1 standards and is designed for passenger, freight, and high-speed elevators. Below is an 800-word English guide covering correct installation, daily operation, and the recommended replacement cycle to maximize safety, ride comfort, and component life.

1. Product Highlights
– Dimensions: 130 mm (L) × 10 mm (T) × 18 mm (W) – drop-in fit for most roller-less guide shoes
– Material: PTFE-reinforced composite with aramid fiber – low friction, high wear resistance
– Hardness: 82 ± 3 Shore D
– Operating Temperature: –40 °C to +120 °C
– Friction Coefficient: 0.08–0.12 dry / 0.05–0.08 lubricated
– Expected Life: 3–5 years or 1.5 million cycles under normal duty

2. Installation Method
Step 1 – Preparation
De-energise the lift; set the car on mechanical safety blocks. Record original lining thickness for comparison.

Step 2 – Removal
Extract split pins and slide the worn lining out of the shoe groove. Clean the groove with 70 % IPA and inspect for burrs or scoring.

Step 3 – Fit New Lining
Slide the 130 mm strip in until flush (±0.3 mm). Re-insert retaining pins; torque M5 screws to 8 N·m. Optional: apply a thin film of Nanjing Zhuye Elevatorparts guide-rail lubricant for break-in.

Step 4 – Commissioning
Run the car at inspection speed (0.3 m/s) for 10 cycles. Check lateral play <0.5 mm, temperature rise <45 °C, and no squeaks.

3. Daily & Preventive Maintenance
Daily (Building Staff)
Visual check for cracks or missing chips; ensure no oil pooling on the lining.

Monthly
Wipe the surface with a lint-free cloth; remove rail dust. Verify tightness of retaining screws.

Quarterly
Measure thickness at three points with a digital caliper; record wear rate. Check rail alignment and lubrication.

Annually
Full dimensional audit and torque re-check. Replace lining if wear exceeds 2 mm or delamination appears.

4. Replacement Cycle & Indicators
| Duty Cycle | Replace Every | Cycles | Warning Signs |
| Residential | 5 years | 1.5 M | Cracks, thickness <8 mm |
| Commercial | 3–4 years | 1 M | Blue heat marks, noise >65 dB |
| Freight / High-speed | 2–3 years | 0.8 M | Surface glazing, vibration |

Replace immediately if:
– Thickness <8 mm (2 mm wear limit)
– Fibre exposure or edge chipping
– Temperature rise >60 °C during normal run

Stock one spare set (4 pieces) per 25 elevators for <4-hour response.
