Checking List for Spline Shaft End Shape

If desiring a ball spline type with its end specially machined, check the following items when placing an order.

The diagram below shows a basic configuration of the Ball Spline.

Check Items

  • Type of the spline nut to be fit
  • Number of spline nuts
  • Clearance in the rotation direction
  • Accuracy
  • With/without a seal (for a single seal, check its orientation)
  • Overall length (including all dimensions? Total value correct?)
  • Effective spline length
  • Hardened area (mark the location with symbol ☆ and indicate the purpose of hardening)
  • Orientation of the flange (for flanged type)
  • Spline shaft end shape (thicker than the minimum spline diameter?) (black, mill scale)
  • Positional relationship between the spline nut and the spline shaft end shape (keyway of the spline nut, flange mounting hole)
  • Indication of chamfering for each part
  • Shape of chamfer on the spline shaft end (see Chamfering of the Spline Shaft Ends )
  • Intended purpose of the though hole in the spline shaft if any
  • o’. Snap ring groove
  • Maximum length
  • Precedented or not
