| By request we can delivery precision shafts in class "S" or class "L" tolerance (or metric - ISO f7 tolerance). | |
Roundness: maximum ½ IT measured as radial deviation
Standard lengths:
- 10.50 ± 1 ft for dia ≤ 0.375 in
- 19.68 ± 1 ft for dia > 0.375 in
Special lengths: by request
The "unchromed length" of each bar (the distance at each end over which the chrome-layer properties and tolerances can not be guaranteed) is at most 5.9 inches/end, maximum 11.8 inches in total / shaft. Fixed or cut lengths can be supplied on request.
Surface roughness: maxRa(CLA) = 8 µin; max RMS = 14 µin
Chrome layer thickness: min. 0.0006 in
Chrome micro hardness: min.950 HV0.1
Straightness
- dia ≤ Ø 0.625 in = max 0.024 in/ft
- dia > Ø 0.625 in = max 0.036 in/ft

Packaging
NIMAX CBXZ bars can be supplied with three packaging options:
- For diameter between 5/8"-4" individually cardboard tubes with caracteristic red and white spiral stripes
- For diameter between 5/8"-3" bundles with max 2205 pounds weight and for diameter ≥ 3" bundles with maximum 3307 pounds weight
- For diameter < 5/8" plastic spacer rings in wooden boxes with maximum 1985 pounds gross weight
Each bundle with weight ≤ 2645 pounds being equipped with two thongs (four for more than 2645 pounds).
On wooden euro-palets from smallest cut lenghts.
Marking
For each bar the cardboard tube will be marked with black colour: "NIMAX CBXZ / diameter/ Tolerance / Steel grade/ heat no. / date".
On each bundle (or wooden boxe / palet) they will be applied minim one label for identification.
