OTIS Elevator Newel Chain 60556202 – Installation, Tensioning & Replacement Guide

The newel chain 60 × 55 × 6202 is the zinc-plated, oil-impregnated roller chain that turns every Otis newel (hall-position indicator) into a silent, self-lubricating billboard. Measuring 60 mm between side plates, 55 mm pitch and fitted with 6202 deep-groove rollers, this 1,500 mm loop keeps the mechanical floor-display drum in perfect sync with the car, even during inspection runs. A single seized pin or 1 % elongation will throw the indicator half a floor out of phase and trigger passenger complaints within hours. Nanjing Zhuye Elevator Parts keeps kilometres of genuine Otis newel chain on reels in Rotterdam and Nanjing so you can restore perfect indication the same day. Below is an 800-word field manual that explains correct usage, on-site tensioning and the replacement cycle that keeps your landings accurate and code-compliant.
1. What the newel chain does
-
8 mm zinc-plated side plates, 2.5 kN breaking load, factory pre-stretched
-
Oil-impregnated bushings give 25,000 h of maintenance-free operation
-
6202-2RS rollers rotate on stationary pins – eliminates sliding wear
-
Pitch tolerance ±0.05 mm keeps cumulative error <1 mm over 3 m travel
-
UL/CE recognised to EN 81-20 and CSA B44.1 for 10-year design life
2. Tools to carry
-
Newel chain 60556202 (Nanjing Zhuye part #OT-CHAIN-60-55-6202) in 1.5 m kit with master link
-
2 mm & 3 mm flat screwdrivers, 10 mm open-end wrench
-
Chain breaker and rivet spinner
-
Feeler gauges 0.05–0.2 mm
-
Spring scale (0–50 N)
-
Otis hand-held service tool (optional for display sync check)
-
Lock-out / tag-out kit
3. Installation – 15 minutes if you mark the sprocket
Safety: place the car on inspection, open the main disconnect and mechanically lock the indicator drum.
-
Mark the old chain position on the 20-tooth sprocket with Sharpie – saves sync time.
-
Remove cotter pin and master link; pull the worn chain out of the newel housing.
-
Clean the sprocket teeth with IPA; check for hooked profiles >0.5 mm.
-
Count 55 pitches (1,505 mm) from the kit; break the new chain at the correct length.
-
Press in the supplied master link; rivet the end pins until head diameter = 1.3 × shank.
-
Feed the loop around drum and sprocket; ensure 6202 rollers seat fully.
-
Adjust tension to 20 N ±2 N at mid-span (10 mm deflection).
-
Cycle the indicator 10 times by hand; verify floor numbers align with car position.
-
Restore power, run 5 full-speed cycles and log the serial number in CMMS.
4. Functional test – prove it to the inspector
a) Chain elongation: <1 % over 1,000 mm (55 pitches).
b) Tension: 20 N ±2 N measured with spring scale.
c) Sprocket alignment: <0.5 mm lateral float.
d) Noise: <45 dB(A) at 1 m during indicator movement.
e) Display sync: floor number must change within 100 mm of car level.
b) Tension: 20 N ±2 N measured with spring scale.
c) Sprocket alignment: <0.5 mm lateral float.
d) Noise: <45 dB(A) at 1 m during indicator movement.
e) Display sync: floor number must change within 100 mm of car level.
5. Preventive maintenance schedule
-
Monthly – visual sweep for rusty links or seized rollers.
-
Quarterly – measure tension; re-grease sprocket with 0.5 g Kluber synth 44-402.
-
Annually – check elongation with 1 m steel rule; replace if >1 %.
-
Every two years – replace the nylon guide shoe – prevents lateral whip.
6. Replacement cycle – traffic and climate decide
Otis specification: 10 years. Nanjing Zhuye analytics refine this:
-
Light duty (<150 starts/day, clean office): 12 years
-
Standard duty (150–400 starts, residential): 10 years
-
Heavy duty (>400 starts, hospital, mall): 8 years
-
Coastal or outdoor (salt, UV): 6 years – zinc plating white-rusts.
Replace immediately if:
-
Elongation >2 % – indicator drifts half a floor
-
Roller seized – flat spot >1 mm diameter
-
Master link cotter missing – risk of separation
-
Tensioner spring bottomed out – chain has stretched beyond take-up
