63 Machined Flexible Chain Sprocket
The 63 machined drive-sprocket range includes six tooth counts. Select the wheel around the actual chain engagement, sprocket bore and available space at the conveyor end.
- Tooth Counts
- 8 / 9 / 10 / 11 / 13 / 15
- Bore Ranges
- 20–30 or 20–40 mm
- Materials
- PA / PP
The listed bore range changes with tooth count. Confirm the required shaft size before choosing a wheel diameter.
Match the Wheel to the Shaft and End Layout
The 8-, 9- and 10-tooth options list a 20–30 mm bore range. The 11-, 13- and 15-tooth options extend that range to 20–40 mm. Tooth count and shaft requirement therefore need to be selected together.
Pitch diameter defines the chain's engagement path, while outside diameter determines part of the physical clearance. Compare both with the drive-end housing. The PA and PP options are material choices for the machined wheel, rather than a statement of equal operating capacity.

Idler Wheel Reference
The 2-63-T16 is a separate machined idler reference for the unpowered return end. It has a 15 mm bore; the drive-sprocket bore ranges above do not apply. Match this idler to the actual chain and axle arrangement before ordering.

Dimensions & Fit
Identify the actual chain and its tooth engagement before choosing a table reference. Confirm whether the shaft needs a round or square bore; provide a keyway drawing where applicable.
Check the selected outside diameter against guards and the chain approach to the wear strips. Hub width and axial position should be confirmed from the ordered drawing, not assumed from the example section.
Drive a Narrow Flexible-Chain Lane
The wheel transfers shaft rotation into the moving chain at the conveyor end. The chain must engage its teeth and return to the support path without interference.
Changing tooth count changes the wheel envelope and the chain's approach to adjacent hardware. A repair that retains the same shaft can still require a clearance check around the housing or transfer. Review the selected diameter before ordering the replacement.
