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.

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
