About the selcom wheel
Elevator and escalator installations are built around a relatively small number of serviceable assemblies, but they fail at very different rates. The selcom 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 selcom 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 selcom 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 Where a superseded revision is the only one available, we say so plainly and explain the substitution, so the installing engineer can make an informed decision rather than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 selcom 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 selcom wheel traces back to a related component that was left in place, or to an adjustment that was assumed rather than measured.
Tension matters as much as wear. A chain that is too slack will whip and hammer its rollers; one that is too tight will load the bearings at both ends of the drive. The correct figure is in the manual, and it is worth setting it with a gauge rather than by feel.
A unit showing a chain that rides visibly high on the sprocket teeth is usually telling you that the drive alignment is checked at the same time, since misalignment wears a new chain faster than an old one.
Belt drives fail differently from chains. A belt does not elongate gradually so much as lose its friction surface, so the first symptom is usually slip under load rather than a change in pitch.
The drive train is where an escalator or lift converts motor torque into motion, and where most of that torque is lost to wear, and the symptom that most often brings an engineer to it is a whine or hammer from the drive that changes with load.
If you are unsure which variant of the selcom 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.
