About This Part
Encoder mounts are journal stacks, and this seat runs them on one axis: Ø6.5 g6 shaft at +0.005/+0.013, Ø10 h7 at minus 0.02, Ø5 h7 at minus 0.01, over a 71.5 plus or minus 0.2 mm length with controlled steps at 58.75 plus or minus 0.05 and 12.2 plus or minus 0.02. End face runout is held at 0.01 A.
Radial features carry the encoder hardware: 2X Ø2 H7 bores 3 mm deep and 2X M2 threads 6 mm deep. The finish is 180 grit bead blast plus black anodize, with the journal classes protected or finished after treatment.
Inspection is micrometer and caliper, CMM on runout and coaxiality, thread gauges, and appearance.

Why Machine It at KGL
Five-Axis Fleet
100+ CNC machines including 11 five-axis centers run complex geometry in single setups, so tolerances do not stack up across refixturing.
Verified Accuracy
±0.005 mm standard on metals, plastics, and carbon fiber composite, verified on Hexagon and Zeiss CMMs (0.0015 mm accuracy).
Fast Prototypes
Engineering feedback with every quotation; prototype parts typically machined in 15 to 25 days.
One Supplier, End to End
Material sourcing, machining, heat treatment coordination, finishing, CMM inspection and export packaging under one roof.

Common Questions
Why so many journal classes on one shaft?
Each mating part gets the class it needs: the encoder, the bearing, the coupling. One axis, three classes, all verified on the CMM together.
Does the anodize move the g6 journal?
It would if ignored. Journal diameters are masked or finished after treatment so the class ships as drawn.
