Ordering the 100-20mm otis wheel
To order the 100-20mm otis wheel, send us a photograph of the existing unit and its nameplate at [email protected]. Please quote the complete code including any revision suffix so that our team can confirm the correct variant, current stock and lead time before you commit.
About the 100-20mm otis wheel
Elevator and escalator installations are built around a relatively small number of serviceable assemblies, but they fail at very different rates. The 100-20mm otis wheel sits in the chains / belts / drives group, and it is replaced on a different service interval from the assemblies around it. In practice the failures we see on 100-20mm otis wheel come down to pitch elongation beyond the wear limit, seized rollers, and sprockets whose tooth profile has hooked after running with a stretched chain.
Every 100-20mm otis wheel we supply is inspected before dispatch. Each unit is checked for physical damage, correct marking and the specific wear or degradation patterns that matter for this class of component, then packed to survive international transit. Where a superseded revision is the only one available, we say so plainly and explain the substitution, so the installing engineer can make an informed decision rather than discovering the difference on site.
Buying guidance and compatibility notes
Before ordering the 100-20mm otis wheel, confirm three things. First, the chain pitch, link count and the number of strands, since a duplex chain will not substitute for a simplex one. Second, chain numbers are frequently local to a manufacturer, so we match on pitch and link count rather than on the printed number alone. Third, whether the installation is a traction lift or an escalator, since duty cycle and loading differ between the two.
On fitting, one point is worth repeating: always measure elongation across at least twenty pitches — a chain that looks acceptable over five links is often past its limit overall. Almost every repeat failure we see on 100-20mm otis wheel traces back to a related component that was left in place, or to an adjustment that was assumed rather than measured.
Joint and connecting links are the weakest point in any run. A chain that has been shortened in the field, or reassembled with a reused connecting link, will almost always fail at that joint rather than in the body of the chain, so the link should be replaced with the chain as a matter of routine.
The underlying cause is usually a hooked sprocket profile that eats a new chain in a fraction of the normal life, which is why the sprocket or pulley part number is often needed alongside the chain, because the pair is what determines service life.
Tensioners and idler wheels are frequently overlooked because they do not carry load in the same way the chain does. A seized tensioner roller turns a simple wear item into a source of vibration, and the resulting noise is often misdiagnosed as a gearbox problem.
Any chain drive is a system, and treating its parts individually is what shortens their life; the chain pitch, link count and number of strands identify the correct part, since a duplex chain will not substitute for a simplex one.
Storage of spare chains matters more than it appears. A chain left coiled in a humid store will corrode at the joints even before it is fitted, and the corrosion is invisible once the chain is installed and lubricated in service.
If you are unsure which variant of the 100-20mm otis wheel you need, send a photograph of the nameplate and the existing component alongside a description of the fault. That is usually enough for our team to identify the correct replacement without a site visit, and it avoids the cost and delay of returning an incompatible part. We are also happy to advise on the other serviceable items in the same chains / belts / drives group, so a planned shutdown can cover several wear items at once.
