company news about What Matters Most in Custom Sprockets? Tooth Count, Bore, Keyway & Tolerance

Custom sprockets must control fit tolerance and mounting interfaces:

• Tooth count / OD: sets ratio and chain speed; affects wrap angle and load distribution.

• Bore size: match shaft diameter with defined tolerances (e.g., H7/h6). Oversize bore causes slipping; undersize complicates assembly.

• Keyway / spline: defines torque capacity. Heavy-load systems often need wider keyways or splines.

• Tooth profile accuracy: higher precision = smoother engagement, lower noise, longer life.
  Specify in drawings: chain standard, tooth count, bore, keyway norm, locating method, and tolerance class.
