Elevator Guide Shoe for KONE & Otis 12/18 mm – Silent, Safe Travel Starts Here | Nanjing Zhuye Elevator Parts
Every smooth ride begins where steel meets polymer. The guide shoe is the small but critical interface that keeps the car and counter-weight running true inside the rail line, absorbing vibration, eliminating metal-to-metal noise and giving passengers that unmistakable “KONE/Otis” feel of quality. Our after-market guide shoe is dimensionally identical to KONE part 854016A and Otis AA39703AB, fits both 12 mm and 18 mm tongues without modification, and is stocked in Nanjing ready for next-day despatch to any continent.

Installation method (car side, top guide shoe)
-
Place car on inspection mode; raise until floor door header is 300 mm above landing sill to allow hand access.
-
Lock mechanical safety gear and switch off main power; tag the feeder breaker.
-
Remove cotter pin and clevis bolt holding the old shoe; slide shoe out of guide bracket.
-
Clean bracket bore with brake-cleaner; inspect for cracks or rust bloom.
-
Insert new shoe so that the 12 mm or 18 mm slot matches the rail tongue; arrow on casting must point toward rail travel direction.
-
Torque clevis bolt to 45 Nm (M10) or 70 Nm (M12) using a calibrated wrench; fit new stainless cotter pin and spread legs 120 °.
-
Apply a 5 mm bead of KONE K96 or Otis 2133C rail lubricant along the top 200 mm of rail for run-in.
-
Restore power; run car on inspection up and down twice while listening for clicking or squealing—absence of noise confirms correct seating.
-
Return to normal mode; log replacement date and initial shoe clearance in the maintenance book.
Counter-weight guide shoes (side-mounted)
Follow the same steps, but always replace both shoes on the same frame end to maintain equal side-play. Tighten bracket eccentric studs until the shoe just kisses the rail, then back off ¼ turn—clearance should be 0.3–0.5 mm. Over-tightening is the single biggest cause of premature insert cracking.
Wear limits & replacement cycle
Under EN 81-20 the residual wall thickness must never fall below 1 mm. Our insert starts at 6 mm; therefore discard when 5 mm has worn away. Field data collected by Nanjing Zhuye Elevator Parts across 42 cities show:
-
Light duty (≤ 300 starts/day, clean shaft): 5–6 years
-
Medium duty (office, 600 starts/day): 3–4 years
-
Heavy duty (hospital, metro, 1 200 starts/day): 18–24 months
-
High temperature (> 45 °C) or paper-dust environments: halve above intervals
Inspect visually every three months; measure with a 0–25 mm micrometer at the thinnest point (mid-height of insert). Replace immediately if:
-
Insert is cracked, chipped or delaminated
-
Aluminium casting shows hairline cracks around pivot bore
-
Car or counter-weight begins to “hunt” at speed > 1 m/s
-
Noise level rises > 55 dB(A) in free-field test
Maintenance tips from Nanjing Zhuye Elevator Parts
-
Never mix old and new inserts on the same frame—differential wear creates rail edge loading.
-
Do not oil the polymer face excessively; dust turns into grinding paste. Wipe once monthly with a dry lint-free cloth.
-
After door-motor replacement or rope re-cutting, re-check guide clearance; rail position often shifts.
-
Store spare shoes horizontally away from UV tubes; nylon swells 0.3 % when exposed to strong sunlight for six months.
-
Keep a set of shoes plus cotter pins in every service van—our data show 70 % of callback noise complaints are solved within 30 minutes by on-the-spot shoe swap.
