Tsubaki 60Q20 Sprocket 60 Chain 20 Teeth

SKU CH-W7SE-7EQE0

Steel 60-chain sprocket with 20 hardened teeth, 4.794 in pitch diameter and 0.459 in tooth width for Q1 split-taper bushings

  • Hardened teeth extend service life
  • 20-tooth design matches 60 chain pitch
  • 1045 steel withstands heavy loads
  • Black oxide finish resists corrosion
  • Split-taper Q1 bushing simplifies installation

TSUBAKI 60Q20 Sprocket for Single-Strand Chain

This hardened-steel sprocket has 20 teeth and fits ANSI 60 roller chain with a 3/4 inch pitch. It is designed for Q1 split-taper bushings and suits power-transmission drives in industrial machinery. The 1045-grade steel body includes a black-oxide finish for corrosion resistance. Buyers needing multi-strand chain engagement cannot use this single-strand hub.

Q1 Split-Taper Bushing Interface Limits

The hub accepts only Q1 split-taper bushings, so the bore size is fixed by that bushing series rather than the sprocket itself. Length through bore measures 1 3/4 inches and hub projection is 1.291 inches, setting the minimum axial space required on the shaft. Installers must verify shaft diameter against Q1 bushing availability before ordering. Drives requiring a different bushing series or a finished bore are incompatible.

Hardened Teeth on 1045 Steel Determine Wear Life

Tooth surfaces are induction hardened while the core remains 1045 carbon steel, giving a hard wear face with a tough ductile centre. Tooth width is .459 inch and pitch diameter is 4.794 inches, defining the chain-wrap geometry for 60 chain. If the application demands a different tooth count, pitch or material grade, this sprocket will not meet the design requirement.

Questions about this item

Should I choose the 20-tooth sprocket or a different tooth count for my 60 chain?

The 20-tooth version gives a 4.794 in pitch diameter and 5.185 in outside diameter; select a different tooth count only if your speed ratio or centre distance requires it.

What does the 4.794 in pitch diameter mean once the sprocket is mounted on a shaft?

It sets the effective radius where the 60 chain engages, so chain speed equals shaft rpm multiplied by 4.794 in divided by 2.

How does the Q1 split-taper bushing interface limit the bore size I can use?

The Q1 bushing accepts shafts up to its maximum bore; the sprocket hub is 3 7/8 in diameter with 1.291 in projection, so the usable bore cannot exceed the Q1 bushing range.
