KONE Elevator Door Hanger CN0454 – Installation, Alignment & Replacement Guide

The CN0454 is the silent workhorse behind every KONE MonoSpace® and MiniSpace® landing door. This precision-machined hanger set—two polyamide rollers pressed onto a galvanized steel bracket—carries the door panel along the aluminum track, absorbing 150 kg of radial load and 3 million open/close cycles without field lubrication. A cracked roller or a worn ball-bearing will first create a faint “click” and quickly escalate to a “34” fault or complete door lock failure. Nanjing Zhuye Elevator Parts keeps thousands of genuine CN0454 hangers in Rotterdam and Nanjing so you can restore whisper-quiet door motion the same day. Below is an 800-word field manual that explains correct usage, on-site alignment and the replacement cycle that keeps your elevators smooth, safe and code-compliant.
1. What the CN0454 does
-
Two 62 mm diameter PA66 rollers with 6201-2RS ball-bearings—greased for life
-
Galvanized steel bracket, 3 mm thick, rated 150 kg per set
-
Floating 4 mm shoulder bolt allows ±2 mm axial float to self-align
-
Noise level <45 dB(A) at 1 m when new
-
CE marked to EN 81-20 and CSA B44.1 for 3 million cycles
2. Tools to carry
-
CN0454 hanger set (Nanjing Zhuye part #KN-HGR-CN0454-OEM) in sealed bag
-
4 mm & 5 mm Allen keys, 13 mm open-end wrench
-
Torque wrench (2–20 N·m)
-
Feeler gauges 0.05–1.0 mm
-
Digital caliper (0–150 mm)
-
KONE hand-held service tool (optional for force curve)
-
Lock-out / tag-out kit
3. Installation – 10 minutes per door if you mark first
Safety: place the car on inspection, open the main disconnect and mechanically prop the door open.
-
Mark the old roller position on the track with masking tape—saves alignment time.
-
Support the door panel with a wooden wedge (prevents drop when hanger is removed).
-
Undo the M8 hanger bolts; lower the worn set onto a rag (grease is slippery).
-
Inspect the aluminum track—polish any burrs with 600-grit paper.
-
Fit the new CN0454: insert shoulder bolt, add Nord-Lock washer, start nut finger-tight.
-
Adjust roller-to-track clearance to 0.2 mm ±0.05 mm using feeler gauge.
-
Torque M8 bolts to 15 N·m in diagonal pattern; apply a drop of blue Loctite.
-
Remove door prop; cycle the door five times on inspection; listen for uniform roller noise.
-
Record serial number, date and clearance values in CMMS.
4. Functional test – prove it to the controller
a) Roller drag force: 3 N ±1 N measured with spring scale.
b) Vertical play: <0.5 mm when lifting the door by hand.
c) Horizontal float: ±2 mm without binding.
d) Noise: <50 dB(A) at 1 m during full-speed cycle.
e) Log all values and export PDF for the site file.
b) Vertical play: <0.5 mm when lifting the door by hand.
c) Horizontal float: ±2 mm without binding.
d) Noise: <50 dB(A) at 1 m during full-speed cycle.

5. Preventive maintenance schedule
-
Monthly – visual sweep for roller cracks or shiny flat spots.
-
Quarterly – measure clearance; re-torque bolts to 15 N·m.
-
Annually – replace door track cleaning pads (prevents abrasive dust).
-
Every two years – grease emergency unlock linkage – not the rollers (they are sealed).
6. Replacement cycle – traffic and environment decide
KONE specification: 3 million cycles ≈ 12 years at 300 starts/day. Nanjing Zhuye site data refine this:
-
Light duty (<150 starts/day, clean office): 15 years
-
Standard duty (150–400 starts, residential): 12 years
-
Heavy duty (>400 starts, hospital, mall): 8 years
-
Outdoor or coastal (airborne salts): 6 years – ball-bearing grease washes out.
Replace immediately if:
-
Roller tread diameter <60 mm (new = 62 mm) – flat spot >1 mm
-
Bearing play >0.3 mm radial – produces “click” every rev
-
Cracked bracket or missing shoulder bolt – safety hazard
-
Door current spikes >20 % – drag overloads VFD

Return the old hanger set in the recycling box; Nanjing Zhuye recovers steel and PA66 and issues a €2 recycling credit. Every CN0454 ships with a 24-month replacement warranty, extendable to 60 months when you join our annual roller-replacement program.
